v17: webhook in multi-db environment

[kmagusiak]

Impacted versions: v17 and onwards

Steps to reproduce:
While trying the new version, I have noticed that webhooks don't work for multi-db environments. I would like to be able to trigger the action using curl or or python requests. Can you provide an example of how to do it.

Current behavior:
Have multiple databases.
Create a webhook automation rule, for example mine is http://localhost:8069/web/hook/c289257e-b598-4276-80d8-9205a1ad7cd6
Since the database is not set, calling the URL in a new session, I get a 404 NOT FOUND error.

Expected behavior:
I should be able to call the webhook in a multi-db environment.

A possibility would be to provide the database name as an http header. A nice addition would be to be able to set a database in settings to which the calls would be routed by default.
