Step 4

Add a webhook URL. This is a mandatory setting and is the callback URL where you will receive inbound messages and delivery notifications directly from Facebook.

Step 5

  • If you chose a Telnyx phone number to register with WhatsApp Business, clicking on this button will open a pop-up window showing the phone number you chose. Click on “Start Integration” button to get started.

    Note: Please do not close this pop-up window as you’ll be receiving your Facebook verification code here while you’re in the registration flow.

  • If you’re using your own phone number to register with WhatsApp, then clicking on this button will launch you into the registration flow powered by Facebook.

Step 6

On the WhatsApp registration flow, you'll be prompted to login to your Facebook account.

Note: If you already have a Facebook Business Manager account that you would like to use for WhatsApp registration, please ensure the Facebook account you’re using to log in has admin access to that Facebook Business Manager account.

Step 7

Complete all the 3 steps in the WhatsApp registration process.

  1. Create/select Facebook Business Manager account and create/select WhatsApp Business account

  2. Create WhatsAp display profile

  3. Verify WhatsApp phone number. Here you will enter the number you chose in Step 3

    Note: If you're using a Telnyx phone number, please select “Text Message” as the mode of verification and you'll see the verification code right on the Telnyx portal

Step 8

Once you have completed the WhatsApp registration process, you'll see your new

WhatsApp Business account created in pending status on the portal.

  • At this point, you can start the business verification process with Meta (Facebook).

  • The approval usually takes 1-2 business days and you will be notified via email

    about the change in account status by Meta.

  • The first phone number in your WhatsApp Business account comes in sandbox
