Facebook messager API webhook does not receive postback callbacks

I have a test application with a verified webhook and a connected test user in the Meta developers console. The webhook has two subscriptions: messages and messaging_postbacks. The webhook receives the messages callbacks but doesn't receive postbacks when the test user clicks postback buttons in the chat. Could you please tell what is the problem?

In the same time it receives test messaging_postbacks from the developer console.

Solution

  • It seems that subscription in the meta developers console interface doesn't work.

    enter image description here

    It requires to sent a POST request like this

    curl -i -X POST "https://graph.facebook.com/PAGE-ID/subscribed_apps
    ?subscribed_fields=messaging_postbacks
    &access_token=PAGE-ACCESS-TOKEN"
