  • Facebook will ask you for a verification token. The verification token is the same as the FB messenger token that you configured earlier.
  • Once this is done, click on the Add Subscription button and subscribe tomessages, message\_postbacks, and message\_options.
  • Add all the necessary approvals, and submit the app for review. Facebook will verify this app after a verification process. Ensure not to make the bot public while creating and testing the bot because Facebook needs to approve the page, and that will take some time. Include the right details about the bot behavior so that the verification process is smooth. Once the app is verified, it will be available on the public page.
  • Once you've filled up all the fields, you can click the Save button to launch the bot. You can test it by opening Facebook Messenger and sending a message to the page. You can also visit your Facebook page > Edit Send Message \> Test Button to have a preview of how your customers would see your page.
