Onboarding business customers as a Tech Provider or Tech Partner

This document describes the steps Tech Providers and Tech Partners must perform to onboard new business customers who have completed the Embedded Signup flow.

If you are a Tech Provider or Tech Partner, any business customer who completes your implementantation of the Embedded Signup flow will not be able to use your app to access their WhatsApp assets or send and receive messages (if you are offering messaging services) until you complete these steps.

What you will need

• the business customer's WABA ID (returned via session logging or API request)
• the business customer's business phone number ID (returned via session logging or API request)
• your app ID (displayed at the top of the App Dashboard)
• your app secret (displayed in the App Dashboard > App settings > Basic panel)

Also, if you wish to test messaging capabilities using the customer's business phone number, you will need a WhatsApp phone number that can already send and receive messages from other WhatsApp numbers.

Step 1: Exchange the token code for a business token

Use the GET /oauth/access_token endpoint to exchange the token code returned by Embedded Signup for a business integration system user access token ("business token").

Request

curl --get 'https://graph.facebook.com/v21.0/oauth/access_token' \
-d 'client_id=<APP_ID>' \
-d 'client_secret=<APP_SECRET>' \
-d 'code=<CODE>'

Request paramaters

Response

Upon success:

<BUSINESS_TOKEN>

Response parameters

Step 2: Subscribe to webhooks on the customer's WABA

Use the POST /<WABA_ID>/subscribed_apps endpoint to subscribe your app to webhooks on the business customer's WABA. Note that you have multiple webhook override options if you want the customer's webhooks to be sent to a different callback URL.

Request

curl -X POST 'https://graph.facebook.com/v21.0/<WABA_ID>/subscribed_apps' \
-H 'Authorization: Bearer <BUSINESS_TOKEN>'

Request paramaters

Response

Upon success:

{
  "success": true
}

Step 3: Register the customer's phone number

Use the POST /<BUSINESS_PHONE_NUMBER_ID>/register endpoint to register the customer's business phone number for use with Cloud API.

Request

curl 'https://graph.facebook.com/v21.0/<BUSINESS_PHONE_NUMBER_ID>/register' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer <BUSINESS_TOKEN>' \
-d '
{
  "messaging_product": "whatsapp",
  "pin": "<DESIRED_PIN>"
}'

Request paramaters

Response

Upon success:

{
  "success": true
}

Step 4: Send a test message

This step is optional.

If you wish to test the messaging capabilities of your business customer's business phone number, send a message to the customer's number from your own WhatsApp number (this will open a customer service window, allowing you to respond with any type of message).

Next, use the POST /<BUSINESS_PHONE_NUMBER_ID>/messages endpoint to send a text message in response.

Request

curl 'https://graph.facebook.com/v21.0/<BUSINESS_PHONE_NUMBER_ID>/messages' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer <BUSINESS_TOKEN>' \
-d '
{
  "messaging_product": "whatsapp",
  "recipient_type": "individual",
  "to": "<WHATSAPP_USER_NUMBER>",
  "type": "text",
  "text": {
    "body": "<BODY_TEXT>"
  }
}'

Request paramaters

Response

Upon success:

{
  "messaging_product": "whatsapp",
  "contacts": [
    {
      "input": "<WHATSAPP_USER_NUMBER>",
      "wa_id": "<WHATSAPP_USER_ID>"
    }
  ],
  "messages": [
    {
      "id": "<WHATSAPP_MESSAGE_ID>"
    }
  ]
}

Response parameters

If you were able to successfully send and receive messages using the customer's business phone number, and if messages webhooks were triggered describing the initial message that you sent, as well as the delivery statuses of the message you sent in response, the customer's business phone number is working properly.

Step 5: Instruct the customer to add a payment method

Instruct your customer to use the WhatsApp Manager to add a payment method. You can provide them with the following Help Center link:

Alternatively, you can instruct them to:

1. Access the WhatsApp Manager > Overview panel at https://business.facebook.com/wa/manage/home/
2. Click the Add payment method button
3. Complete the flow

Once your customer adds a payment method, they are fully onboarded onto the WhatsApp Business Platform and can begin using your app to access their WhatsApp assets and send and receive messages (if you are providing them with that service).
