Hello. Since Prefect 1.0 had the ability to send Automations to a generic Webhook URL, we had an automation set up to a Microsoft Power Automate webhook that we had running. Prefect 2.0 does not have a generic Webhook URL action for Automations that I saw, so I went ahead and created my own by inheriting

AppriseNotificationBlock

. I went ahead and registered the custom block I created with the UI and created a block under my Blocks page with the webhook URL. When I

.load()

the block from local python client and call

.notify()

on it, it works perfectly. I thought it would work just the same if I add it as an Action on the Automations tab, but to my surprise, it fails every time. I see the failed events on the Events tab of the automation I set up. Is there a way to see what is causing the failure?

Hey Carlos, thanks for raising this. I’ll be looking into this with the team tomorrow.

Thank you. Appreciate it.

Hey Carlos - currently for security reasons we dont actually support custom block types in these action, including those that extend a base class we support. That said, we’re going to be adding in a generic webhook action in the next month, so that should solve your issue.

Perfect. Thank you for looking into it Will. Appreciate it. I’ll be looking forward for the generic webhook action. Appreciate the help.

You got it, thanks for raising the friction.
