Overview of account linking for Apple Business Chat

You can use an interaction to prompt the user to log into a third-party account. The interaction for account linking needs:

  • The Requires account linking option to be set (on its Advanced tab)
  • An Account Link button that initiates the login on the user's device.

Authentication is handled by the client's OAuth server and Apple Business Chat. See Prerequisites for account linking on Apple Business Chat.

Once the user has signed in successfully, Apple Business Chat will send an access token to the bot. See Using the returned authorization code.

The following diagram provides an overview of the account linking process.
