Creates a new webhook. The provided URL should respond with a 200 HTTP status. After
creation, the URL will receive notifications when events on documents in the
administration occur. It is also possible to subscribe to certain events by adding an array
with events you would like to receive notifications from.
We strongly recommend that you use a secure HTTPS endpoint for receiving payload from Moneybird.
If you use unencrypted HTTP, anyone on the network may be able to listen in on sensitive information like contacts and invoices.
