The two webhook payloads for app canvas interactions and initializations will have their type key within the message attribute changed from:

1. v2-alpha.canvas.interaction to v0-beta.canvas.userInteracted
2. v2-alpha.canvas.initialize to v0-beta.canvas.initialized

These changes are effective March 3rd 2023.

What’s changing?

The webhook OpenAPI spec correctly described the type in message, however the server was sending the payloads with an erroneous v2- prefix and wrong suffix in the response.

Other webhook types are unaffected.

When is this happening?

The new canvas interacted webhook payoad will start returning updated types starting March 3rd 2023.
