I have created a webhook for an Online customer which fires for appointment.created.
From time to time it start firing double, and continues to do so until something is done. Last time this morning. It worked fine yesterday, so something must have happened during the night.
It's easy to fix. You just have to set the state of the webhook to 2 (inactive), and then 1 again (active). But it's annoying that this is something that manually has to be done.
Any suggestions to how this can be debugged?
