Coexistence Onboarding

This section provides details on how to onboard businesses that are already using the WhatsApp Business App and want to expand to the WhatsApp Cloud API.

Requirements

Before onboarding a number to WhatsApp Coexistence Mode, make sure:

  • The phone number has been actively using the WhatsApp Business App for at least 7 days.

  • The latest version of the WhatsApp Business App is installed on a smartphone with a camera (QR code required).

  • The number is not from a restricted region.

You can create a new Meta Business Account or connect to an existing one during the Embedded Signup process.

Please choose your Business Manager carefully, since it can't be changed after the number is registered. It is mandatory that the Business Manager is owned by the Business who is sending messages. Adding users who do not belong to this company can cause your Business Manager to be blocked.

You must add your information in the Business Info section of Business Manager Settings. You need to include a legal name, an address, a website, and the business phone number you intend to use for messaging.

Step-by-Step Procedure

  • Go to Settings > WhatsApp Accounts.
