CallbackInput not called

Hey everyone, I’ve used the rasa rest api to communicate with my bot. POST requests via http://rasa:5005/webhooks/rest/webhook work fine. And in the response I’m also getting my bot’s reply. But I wanted to not rely on the reponse of /webhooks/rest/webhook and instead using the CallbackInput described here Your Own Website But for some reason the CallbackInput is not called. I double checked that my endpoint is reachable from rasa. But no success. I wonder if I misunderstood the concept of the CallbackInput?

I found the Issue. Its a subtle thing in the docs. To get the async callback request via the CallbackInput you have to use in general a different url http://<host>:<port>/webhooks/callback/webhook instead of http://<host>:<port>/webhooks/rest/webhook. Described here Your Own Website
