Powerautomate webhook url update 2025-11-30

[simonhunoldregnology]

I was currently getting emails regarding the update of Power Automate where they state that the previous versions of the webhook URL are no longer supported as of 2025-11-30.
I now tried to use the new url and also conisdered the following instructions: https://github.com/caronc/apprise/wiki/Notify_workflows

However, I am always receiving errors:

2025-09-08 11:41:17,798 - DEBUG - Loaded Power Automate / Workflows (for MSTeams) URL: workflow://%host%:443/b...2/W...0/?image=yes&wrap=yes&format=markdown&overflow=upstream

Could someone please tell me whether the new URLs are already supported or how I could make them work?

Thanks in advance

Using the wrong scheme (workflow://), it must be workflows:// (plural). ?

Your URL still contains a placeholder for the host: %host%. That needs to be the actual Logic Apps host from your Flow’s HTTP trigger URL (e.g., prod-21.westeurope.logic.azure.com).

Yes this is exactly what I did:

The url with "workflow" I can also only see inside the debug logs in the UI

related to this upstream issue i think caronc/apprise#1405

Thanks for finding the related issue. I guess we then just need to wait for it to be merged.
