# Set up and integrate the Tech Provider Program Integrating WhatsApp Business with your system requires setting up a Meta app, registering as a Meta Developer, and configuring key components such as business verification and partner solutions. Follow these steps to ensure a smooth setup and seamless integration with the **Infobip platform**. ## Setup Before you begin using WhatsApp Business, you need to configure your business portfolio, register as a Meta Developer, and create a Meta app. These steps help establish your business presence and enable WhatsApp sender registration. ### Create a business portfolio [#create-a-business-portfolio-setup] To get started, you can either [create a new business portfolio](https://business.facebook.com/create) or review and update your existing one to include all the required business details, such as business address, website, and email. Ensure that the account creator or owner can provide accurate information about the business during the business verification process later. Things to keep in mind: - Your business can have up to two business portfolios. - Ensure all the information provided is correct. Otherwise it will be rejected during the business verification stage. ### Register as a Meta Developer [#register-as-meta-developer-setup] If you are not already a registered Meta Developer, you must register first to access Meta's developer tools, APIs, and the App Dashboard. 1. **Start the registration process** - Log into your **Facebook account** and go to [Meta Developer Registration](https://developers.facebook.com/async/registration). - Alternatively, visit the [Social Technologies Dev Center](https://developers.facebook.com/) and select **Get Started**. 2. **Accept the terms and policies** - Select **Next** to agree to Meta's [Platform Terms](https://developers.facebook.com/terms) and [Developer Policies](https://developers.facebook.com/devpolicy). 3. **Verify your account** - Enter a valid phone number and email address. - Meta will send a confirmation code to both for verification. - These contact details will be used for important developer notifications. 4. **Select your occupation** - Choose the occupation that best describes your role. Once registered, you can use the App Dashboard to create and manage your apps. ### Create and set up a Meta app [#create-and-set-up-meta-app-setup] To integrate WhatsApp with your business portfolio, you need to create a new Meta app. Even if you already have a Meta app, it is recommended to start with a new one. Reusing an existing app provides little benefit unless you have already completed the WhatsApp Tech Provider process for another BSP or directly with Meta. 1. Navigate to the [**My Apps**](https://developers.facebook.com/apps/creation/) panel and select **Create app**. NOTE The name of your Meta app, along with your business portfolio name, will be visible to customers during the WhatsApp Sender registration process. Do not include Meta trademarks, such as _WhatsApp_, in the app name. 2. Enter your **app name** and **contact email**, then select **Next**. 3. Under **Use cases**, select **Other**, then select **Next**. 4. For **Type**, select **Business**, then select **Next**. 5. Under **Details**, verify the following and select **Create app**: - **App name**: Enter the name of your application. - **App contact email**: Provide an email address for support. - **Business portfolio**: Select your business portfolio from the dropdown menu. Note If you cannot complete this step, try selecting **No business portfolio** selected on the **Business portfolio** dropdown. 6. Once the app is created, navigate to it in your **App Dashboard** and go to **Settings** > **Basic**. Update the following details: | Field | Description | | --- | --- | | **App ID** | A unique identifier automatically assigned to your app. It must be included in API requests and cannot be changed. | | **App secret** | A confidential key used for authentication and generating access tokens. Keep it secure and do not expose it in your code. | | **Display name** | The name of your app that will be visible to users. Ensure it follows Meta's naming guidelines and does not include trademarks like _WhatsApp_. | | **Namespace** | A unique identifier for your app's Canvas page, used to provide additional information about your app. | | **App domains** | The primary domains and subdomains associated with your app. These are used for app installation and Graph API verification. | | **Contact email** | The email address where developer notifications will be sent. This field is required to switch your app to Live mode. | | **Privacy policy URL** | A link to your app’s privacy policy, which must clearly explain how user data is handled. | | **Terms of service URL** | A link to your app’s terms of service, required when switching to Live mode. | | **User data deletion** | An URL with instructions for users on how to request deletion of their data. This link is used when users remove your app using Facebook settings. | | **App icon** | A visual representation of your app in the App Center. Follow [Meta's guidelines](https://developers.facebook.com/docs/development/create-an-app/app-dashboard/basic-settings#app-icon) to avoid rejection. | | **Category** | The category that best describes your app. This helps users discover your app more easily. | Note **Privacy Policy** and **Terms of Service** URLs will be visible to users onboarding through the [WhatsApp sender registration process](https://www.infobip.com/docs/whatsapp/get-started/embedded-signup). 7. Under **Category**, choose **Messaging**. ### Add the WhatsApp product [#add-whatsapp-product-setup] 1. Navigate to the **Dashboard** within your Meta app. 2. Find **WhatsApp** and select the **Set up** button underneath it. 3. Accept [Facebook Terms for WhatsApp Business](https://www.whatsapp.com/legal/meta-terms-whatsapp-business) and the [Meta Hosting Terms for Cloud API](https://www.facebook.com/legal/Meta-Hosting-Terms-Cloud-API), then select **Continue**. You will be redirected to the **Quickstart** page. You can then either start testing the environment using a full-featured sandbox or immediately scale your business by becoming a Tech Provider. 4. On the **Quickstart** page, go to the **Improve ROI with marketing messages with optimization** and select **Get started**. 5. Select **Request permission** to add any missing app review permissions. 6. Select **Continue** to accept the terms of service. Once you have your integration with WhatsApp set up, you can start testing your setup and scale your business as a Tech Provider. #### Scale your setup as a Tech Provider 1. Navigate to **App Dashboard** > **WhatsApp** > **Quickstart**. - Under **Scale your business** card, select **Start onboarding** to become a Tech Provider. Note If you have already added the product to your app, but have not accepted the terms, go back to the **Quickstart** section to complete this step. 2. Choose **Working with a Solution Partner** and then select **Start onboarding**. 3. Complete [business verification](https://www.facebook.com/business/help/2058515294227817?id=180505742745347) by selecting **Start verification**. - Meta uses this process to confirm that you are associated with a legal entity. - Be sure to upload the required [official documents](https://www.facebook.com/business/help/159334372093366) and follow the guidelines on [domain verification](https://www.facebook.com/business/help/245311299870862). - Business verification usually takes 2–5 business days. - If your request is not approved, Meta will provide feedback to help you resubmit it. Note Your business needs to be verified before using the [WhatsApp sender registration process](https://www.infobip.com/docs/whatsapp/get-started/embedded-signup). ### Submit the Meta app for review [#app-review-setup] NOTE Your business must complete business verification and be verified in order to complete app review. [App review](https://developers.facebook.com/docs/resp-plat-initiatives/individual-processes/app-review) is a required step to allow apps to access specific WhatsApp features. Since your app will manage another business's WhatsApp Business Account and send messages on their behalf, Meta needs to validate how you intend to use the requested permissions to prevent abuse or harm to user data. Meta's operational team will review your submission and either approve, reject, or request additional information. #### Prepare for app review To prepare for the [app review](https://developers.facebook.com/docs/app-review/), follow the steps below: 1. **Build your prototype** - Complete your app development and ensure that it complies with Meta's [Platform Terms](https://developers.facebook.com/terms) and [Developer Policies](https://developers.facebook.com/devpolicy). - Your website can subscribe to webhooks to receive updates on a user's WhatsApp Business Account. 2. **Review app settings** - Go to your Meta app's **Onboarding** page and select **Review your app settings**. - Ensure that the following information is correctly set: - **App icon** (1024 x 1024 px) - **Privacy Policy URL** - **App category** 3. **Record video documentation** - As part of the app review process, you will need to provide a video recording for each permission you request. Refer to [Meta's guidelines on screen recordings](https://developers.facebook.com/docs/app-review/submission-guide/screen-recordings), but keep a few things in mind while recording: - Use English as the app UI language - Provide captions and tooltips if your app is not available in English - Explain the meaning of buttons and other UI elements. NOTE If you have an existing Infobip integration, you can record these actions on our [web interface](https://portal.infobip.com/login). #### Start the app review You can start the app review process in the **App Dashboard**. This step ensures that your app meets Meta and WhatsApp requirements. Follow these steps to initiate the review: 1. **Request permissions** - Permissions are granular, user-granted authorizations. Before your app can use a service to access an app user's data, the user must grant all permissions required by that service. To pass the app review, request only the permissions necessary for your app to function, as asking for unnecessary permissions is a common reason for rejection. - On the **App Review** > **Permissions and Features** page, find the required permissions: - `whatsapp_business_management` - `whatsapp_business_messaging` - Select **Request advanced access**, then **Continue request** to start the review process. 2. **Submit business verification** - If you have completed business verification, this step will be marked as complete. - If you have not completed business verification, you [must do so](https://www.facebook.com/business/help/2058515294227817?id=180505742745347) before proceeding. 3. **Answer data handling questions** - Provide information about your data handling practices, including: - Your data controller and its location - The company name for each data processor - Processes in place for handling public authority requests regarding access to personal data - If your submission is not approved, Meta will provide feedback to help you resubmit it. 4. **Complete app verification** - Submit instructions for each platform where your app will be available (iOS, Android, web). - Explain why and how your app uses each requested permission by submitting a text explanation and a video for each permission, highlighting where the respective permissions are used. Ensure your video submissions showcase your product (website or mock-ups) and not Infobip or Meta products. - `whatsapp_business_management` - **Text explanation** - Explain how your app or API manages a customer’s WhatsApp account, including account details, message templates, and other WhatsApp assets. Highlight how your platform enables customers to control their account settings and assets. - **Video requirements** - Your video or screen recording must demonstrate your app being used to create a message template or show the WhatsApp Manager being used by you to create a message template. - Alternatively, you can capture a screen recording of [WhatsApp Manager](https://business.facebook.com/latest/whatsapp_manager) as you use it to create a template message. - `whatsapp_business_messaging` - **Text explanation** - Describe how your app uses this permission to send messages on behalf of your users. Explain whether messages are sent through an API or an application you have developed, and how it benefits your users. - **Video requirements** - Your video or screen recording must demonstrate a message being sent with your app and appearing in the WhatsApp client. - Alternatively, you can screen record the [API Setup cURL script](https://www.infobip.com/docs/api/channels/whatsapp/whatsapp-outbound-messages/send-whatsapp-template-message) as you use it to send a message to a WhatsApp number designated as a test recipient. 5. **Submit for review** - Once you have completed your app verification, select **Submit for review**. - Meta usually responds in 3-5 business days with either a full or partial pass or fail. - You can use approved permissions right away, and for denied permissions, Meta will provide you its feedback to help you resubmit. ### Access verification [#access-verification-setup] Meta requires **access verification** to ensure that only businesses with a legitimate use case can access another business's data. Access verification confirms that a business is eligible to act as a Tech Provider and handle business data securely. Once your Meta app is approved, you must complete Meta's access verification to confirm that your business operates as a Tech Provider. **Prerequisites:** - To start the process, you must be the **business admin**. - **Business verification** must be completed. - The **business account must not have any [restrictions](https://www.facebook.com/business/help/422289316306981)**. **Verification steps:** 1. Go to your **App Dashboard**. 2. Navigate to **App settings** > **Basic**. 3. On the **Verifications** card, select **Start verification**. 4. Provide the required information, including how your business uses other businesses' data to provide a service. 5. Submit your request. Meta typically reviews and provides a decision within approximately 5 days. Once your verification is **approved** or **denied**, you will receive either a **confirmation email** or a **rejection email**. Once verified, businesses **do not need to verify again**, though [under certain conditions](https://developers.facebook.com/docs/development/release/access-verification/#losing-verified-status), verification may be temporarily revoked. If a rejected business' use case changes, a business admin may reapply for verification. ## Integration During this phase, you can build your end-to-end product experience. Make sure you adhere to the [Meta and WhatsApp terms](https://web.facebook.com/business/help/363303621411154?id=818859032317965&_rdc=1&_rdr) with regard to user data handling when you build your solution. ### Partner solutions with Infobip [#partner-solutions-with-infobip-integration] The core of the Tech Provider model is the partner solution, configured in the **App Dashboard**. This setup defines the WhatsApp assets you and Infobip can access for your end clients. Once approved, the setup allows you to customize the embedded signup process. During this process, your end clients can grant access to these assets for both business entities. #### Create a partner solution [#create-a-partner-solution-integration] A **partner solution** establishes an asset-sharing relationship between two business entities. To configure, initiate, and accept it, open the following panel: - **App Dashboard** > **WhatsApp** > **Partner solutions**. Partner solutions can have the following states: | State | Description | | --- | --- | | **Active** | Infobip has accepted the solution and you can use it to configure sender registration flow for end-client onboarding. | | **Pending** | Infobip has not accepted or rejected the solution. End clients who try to access the sender registration flow configured for a solution in this state will see an error indicating it cannot be used for onboarding. | | **Draft** | The solution has been initiated and saved but has not been sent to Infobip. End clients who try to access the sender registration flow configured for a solution in this state will see an error indicating it cannot be used for onboarding. | | **Inactive** | Infobip declined the solution request. End clients who try to access the sender registration flow configured for a solution in this state will see an error indicating it cannot be used for onboarding. | | **Pending deactivation** | Infobip has requested to deactivate the solution. You can accept or decline this request. | | **Deactivated** | The solution has been deactivated. End clients who try to access the sender registration flow configured for a solution in this state will see an error indicating it cannot be used for onboarding. | You can use each solution to onboard up to 200 end clients in a rolling one-week period. #### Add Infobip app to the partner solution To add the Infobip app to your partner solution, follow these steps: 1. **Collaborate with Infobip to determine a solution name** - Work with Infobip to decide on a solution name that will appear in the **WhatsApp** > **Partner solutions** panel in the **App Dashboard**. This name helps you and Infobip easily identify the solution, among others. 2. **Initiate a partner solution request** - Once you have agreed on the solution name, access the **App Dashboard** > **WhatsApp** > **Partner solutions**. 3. **Create a partner solution** - In the **Partner solutions** panel, select **Create a partner solution**. - Enter the agreed solution name. 4. **Enter Infobip app ID** - Provide the Infobip app ID: `1370401139746733`. 5. **Configure permissions** - Next to **Send messages**, choose **Only my partner**. 6. **Complete the partner solution request** - Follow the prompts to complete the process and initiate the partner solution request. After the partner solution request is complete, Infobip receives an email and notification in **Meta Business Suite** about your request. The solution appears in the **Partner solutions** panel with a `Pending` status until Infobip accepts it. When Infobip accepts the partner solution request, the status changes from `Pending` to `Active`. Once the status is active, copy the **Solution ID** and add it during the embedded signup configuration. ### Sender registration setup [#sender-registration-setup-integration] After confirming your status as a Tech Provider, you can start onboarding business customers. Your users must complete the [sender registration](https://www.infobip.com/docs/whatsapp/get-started/embedded-signup) setup, which Meta refers to as **embedded signup**. To enable this process, first, add a **Login with Facebook** button to your UI. This button will launch the sender registration flow. Once users complete the registration, the required WhatsApp assets are automatically generated, and access to these assets is granted to both you and Infobip. #### Set up your configuration Before setting up the sender registration flow, you must create a **login configuration**. This configuration allows customers to log into their Facebook account and complete the flow. To do so, follow these steps: 1. Log in to [Meta for Developers](https://developers.facebook.com/) and go to your **Tech Provider** app. 2. In your **App Dashboard**, go to **Facebook Login for Business** > **Configurations**. 3. Create or update the login configuration: - To create a new configuration, select **Create configuration** and give it a descriptive name (for example *updated_config_sender_registration*). - To update an existing configuration, find it in the list and select **Edit** next to its name. 4. On the **Login variation** screen, select **WhatsApp Embedded Signup**, then select **Next**. 5. On the **Products** screen, select **WhatsApp Cloud API** and **Marketing Messages API for WhatsApp**, then select **Next**. 6. On the **Access token** screen, under **Choose token expiration**, select **Never**, then select **Next**. 7. On the **Assets** screen, select **WhatsApp accounts** and choose the following permissions: - `MANAGE` - `DEVELOP` - `MANAGE_TEMPLATES` - `VIEW_PHONE_ASSETS` - `VIEW_TEMPLATES` - `MESSAGING` 8. On the **Permissions** screen, verify that the following permissions are included: - `whatsapp_business_management` - `whatsapp_business_messaging` 9. Select **Create** and save the **configuration ID** (`config_id`) provided by Meta. #### Manage allowlist To ensure smooth onboarding and secure authentication, you must configure your **Facebook Login for Business** settings and allowlist the necessary domains. This step is required for the sender registration process to function correctly. To update your login settings, follow these steps: 1. Go to your **App Dashboard** and navigate to **Facebook Login for Business** > **Settings** > **Client OAuth settings**. 2. Enable the following options: - **Client OAuth login** - **Web OAuth login** - **Enforce HTTPS** - **Embedded Browser OAuth Login** - **Use Strict Mode for redirect URIs** - **Login with the JavaScript SDK** 3. Add your domain into Valid OAuth redirect URIs and Allowed domains for the JavaScript SDK. IMPORTANT Ensure all domains use **HTTPS** and are **static** (wildcards or dynamic URLs are not supported). 4. Select **Save changes** to apply the settings. #### Update roles You can add team members to your **Meta app** to grant them access as **admins** or **developers**. Be cautious when assigning admin roles; only grant them to users who require full access. Added team members will be able to test your sender registration integration. To update the roles, follow these steps: 1. Open your **App Dashboard**. 2. Navigate to **App roles** > **Roles** panel. 3. Select **Edit roles** in **Business Manager**. 4. Select **Assign people** and add the necessary admins and developers. This button shows the embedded signup code with several pre-filled values, such as your app ID. Make sure to assign your permission configuration ID to the `config_id` property in the script. #### Configure sender registration flow To enable businesses to complete the sender registration flow, you must integrate **Facebook Login** into your application. This ensures that users authenticate with their Facebook account and provide the necessary permissions to link their **WhatsApp Business Account (WABA)**. The sender registration flow requires the **Facebook JavaScript SDK** to be loaded before initiating the login flow. The SDK handles authentication and allows your application to retrieve the necessary credentials for setting up a WhatsApp Business Account. 1. **Load the Facebook JavaScript SDK** - Before launching the signup flow, initialize the **Facebook JavaScript SDK** by adding the following script to your web page. - `APP_ID` should be replaced with the Meta app ID associated with your business. - This script loads the Facebook SDK asynchronously, ensuring it does not block the page from rendering. 2. **Implement the login flow** - Once the Facebook SDK is loaded, you can launch the **Facebook Login** flow to authenticate users and retrieve their WhatsApp Business Account (WABA) ID. - The following **JavaScript snippet** defines a function that triggers the **Facebook Login** flow. When a user logs in, the script retrieves an access token, which is required to fetch the WABA ID for further setup - **Configuration details**: - `CONFIG_ID`: Replace with your **configuration ID**, described in the **Set up your configuration ID** section. - `SOLUTIONID`: Replace with your **solution ID**, which identifies the WhatsApp Business integration. - The following HTML snippet creates the button that, when clicked, initiates the **Facebook Login flow**. - When a user clicks the **Login with Facebook** button, the script prompts them to log in and authorize access. - If the user grants permission, the script retrieves an **access token**, which is required to fetch the associated **WABA ID** for further setup. #### Billing End clients onboarded through the embedded signup (configured for a partner solution) share Infobip's credit line. Infobip handles billing for any end-client API usage and charges the solution to you. You can bill your clients directly for your value-added solution or service. #### Customer registration After customers complete the sender registration flow on your site, notify Infobip by triggering the designated API endpoint. This step ensures that the WhatsApp Business Account (WABA) ID is shared with Infobip for further processing. - Endpoint: POST ```/whatsapp/1/embedded-signup/registrations/share-waba``` curl -X POST "https://api.infobip.com/whatsapp/1/embedded-signup/registrations/share-waba" \ -H 'Authorization: {authorization}' \ -H 'Content-Type: application/json' \ -d '{ "businessAccountId": "WABA_ID" }' #### Webhook registration event Infobip sends real-time notifications to your webhook when there are changes to a WhatsApp Business Account (WABA) registration status. The possible statuses are: - `IN_PROGRESS`: Registration is ongoing. - `FAILED`: Registration was unsuccessful. - `FINISHED`: Registration is complete. To enable webhook notifications, provide your webhook URL to your Infobip account manager or contact [Support](https://www.infobip.com/contact). The payload also includes the following fields: - `registrationInfo`: Present at both the top level and per sender. Provides the registration outcome or a detailed failure reason, so you can diagnose issues without additional API calls. - `businessPortfolioId`: Maps the registration to the entity ID automatically created during the onboarding flow. This is useful for Tech Providers using the full CPaaS X feature set. { "businessAccountId": 123456789012345, "status": "FINISHED", "createdAt": "2023-06-07T15:17:37.444+0000", "lastModifiedAt": "2023-08-28T17:01:04.904+0000", "senders": [ { "phoneNumberId": "111222333444555", "displayPhoneNumber": "15551002000", "type": "CLOUD", "status": "FINISHED", "registrationInfo": "Successfully registered" }, { "phoneNumberId": "666777888999000", "displayPhoneNumber": "15553004000", "type": "CLOUD", "status": "FAILED", "registrationInfo": "Meta error response received: (#133016) Registration or Deregistration failed because there were too many attempts for this phone number in a short period of time." } ], "businessPortfolioId": 987654321098765, "registrationInfo": "Successfully registered" } #### Automatic resource association The system can automatically associate WhatsApp resources with an application ID and entity ID during the WhatsApp sender registration through the embedded signup flow. This feature links WhatsApp resources to the correct application and entity IDs as they are created, simplifying the management of multiple customer accounts. For example, when a Tech Provider receives a subscription event with a default entity ID, they can quickly assign the appropriate entity and application IDs for a new customer, ensuring smooth onboarding and efficient resource allocation. The system will automatically assign the entity ID to match the end user's Business Manager ID received from the registration event. Users can modify the entity IDs afterward if necessary. ### Implement template and traffic management APIs [#implement-template-and-traffic-management-apis-integration] To manage WhatsApp traffic effectively, you can use APIs that support message sending, template configuration, service orchestration, and reporting. Whether you are using the standalone **WhatsApp API** or integrating through Infobip's unified solutions like **Messages API** and **CPaaS X**, these tools help you scale, automate, and maintain compliant communications with users across the full messaging lifecycle. #### WhatsApp standalone API When you send a WhatsApp message to an end user's device, you are sending an **outbound message**. There are several types of WhatsApp messages: - **Message templates**: Pre-defined and pre-approved templates used to send text, images, videos, locations, documents, carousels, and buttons, with options to configure SMS failover. - **Free-form messages**: Messages you can use when the end user contacts you within a certain timeframe. You can send text, images, audio, video, stickers, locations, or contacts without Meta's pre-approval. They can include **interactive elements** like buttons, lists, or product messages for user engagement. When an end user sends a WhatsApp message from their device to your phone number, it is an **inbound message**. The inbound message is routed through the Infobip platform and delivered to you. Common actions with inbound messages include: - **Marking messages as read** to indicate to the end user that their message has been seen. - **Downloading media and metadata** shared by the end user. Learn more about integrating [outbound and inbound WhatsApp traffic](https://www.infobip.com/docs/api/channels/whatsapp/whatsapp-inbound-messages). #### Service management Effective service management for WhatsApp business solution involves maintaining seamless communication and engagement. Key aspects include: - **Template management**: Design and maintain pre-defined message structures that comply with WhatsApp guidelines to ensure consistent communication with customers. - **Sender management**: Manage registered WhatsApp sender to align with business representation and maintain high communication standards. Implementing robust service management practices ensures compliance, reliability, and optimal performance, leading to better customer interactions on the WhatsApp business solution platform. Learn more about WhatsApp business solution service management. #### Message status reports Message status reports provide insights into the delivery and engagement of messages in WhatsApp business solution management: - Delivery reports: Confirm the successful message transmission from the business to the recipient's device, ensuring message reachability. - Seen reports: Indicate when a recipient has viewed the message, offering deeper insights into user engagement. Effective management of these reports involves capturing, processing, and interpreting data from Infobip APIs, allowing businesses to monitor message effectiveness and refine their communication strategies. #### Messages API WhatsApp outbound and inbound traffic can also be managed through the **Messages API**, which integrates multiple messaging channels into a single interface. Instead of using separate APIs for each channel, you can manage all channels with one API. - **Unified endpoint**: All channels use the same endpoint, enabling consistent message sending, receiving, and other actions across all channels. - **Future-proof solution**: Ideal for businesses using multiple channels or planning to expand, reducing integration efforts and simplifying management. Find more information in the Messages API [product documentation](https://www.infobip.com/docs/messages-api) and API details page. #### CPaaS X **CPaaS X** is our next-generation _Communication Platform as a Service (CPaaS)_ API stack designed to make your messaging experience more scalable, modular, and efficient. With **CPaaS X**, you are already leveraging its capabilities during the automatic resource association process. This feature automatically creates and assigns **entity ID** and **application ID** during WhatsApp sender registration, reducing manual effort and ensuring smooth onboarding. Beyond this, **CPaaS X** provides additional features that you can explore and integrate, including advanced messaging capabilities, analytics, automation, and seamless scaling options. Take advantage of CPaaS X to streamline your messaging setup and explore how its [modular and flexible APIs](https://www.infobip.com/docs/cpaas-x/) can further support your business needs. ### Validate and test your setup [#validate-and-test-your-setup-integration] Once you have set up the sender registration process, ensure it is accessible on your website, where you can test it. To test embedded signup, simulate a customer completing the flow using test business credentials generated from your platform. To validate that your sender registration setup is correct, confirm the following: - **Successfully register a number** using the sender registration flow hosted on your platform. - **Successfully send messages on behalf of your customer** using Infobip traffic APIs, such as WhatsApp or Messages API, based on your preference. If your app is not yet reviewed, you can only onboard test accounts through the sender registration process. The WhatsApp business account (WABA) you create for testing cannot be associated with your Tech Provider's Facebook Business Manager. You must create a new Business Manager account using the sender registration process. To successfully create a test WABA, the person performing the setup must have admin rights on both the newly created Business Manager account (admin rights are automatically assigned upon creation) and the Tech Provider Business Manager account. This limitation does not apply to production environments. ### Launch your setup [#launch-your-setup-integration] You are almost there! 🚀 Once your app has been reviewed and your **sender registration flow** is fully set up and tested, it is time to go live.
