@dosubot[bot] commented on GitHub (May 23, 2025):

The 404 error occurs because the endpoint you tried (/v1/messages/{message_id}) does not exist in Dify's API. Based on the codebase, the correct API endpoint for deleting a message is:

DELETE /installed-apps/<uuid:installed_app_id>/saved-messages/<uuid:message_id>

This endpoint is implemented in the SavedMessageApi class and will delete the specified message if the request is valid. Make sure to replace <uuid:installed_app_id> with your installed app's UUID and <uuid:message_id> with the UUID of the message you want to delete. The request should include your Bearer token for authorization.

Example request:

DELETE {{baseUrl}}/installed-apps/{installed_app_id}/saved-messages/{message_id}
Authorization: Bearer {api_key}

A few things to check if you encounter issues:

  • Ensure you are using the correct installed_app_id and message_id.
  • The app must be in "completion" mode for deletion to be allowed.
  • Your user must have the necessary permissions.

There is no comprehensive public API documentation for this, so these details are based on the code implementation. You can see the relevant code and endpoint definition here.

If you continue to have trouble, double-check the UUIDs and your permissions.
