What it's for

By connecting Messenger, the messages people send to your Page arrive in the Chat section, where the AI can respond and operators can step in.

Connect Messenger to SendApp

1. 1

   Open "Applications" and choose "Messenger"

   From the Applications menu, select the Messenger channel and the Account to connect it to.

2. 2

   Authorize with Meta

   The official Meta window opens: sign in and grant permissions on the Page. The screens are managed by Meta — follow the on-screen instructions (and Meta's Help Center if you have any doubts).

Reply window

As on other Meta channels, there are rules about the reply window: for certain out-of-window messages, Messenger requires the use of specific tags. SendApp handles sending according to the platform's rules.

Common errors

Check that you authorized the correct Page and that you have management permissions for it on Meta.
