Subscribing to Webhooks and Microsoft's "Your flow has a new trigger URL"

Hello,

With the announcement of Microsoft's new URL changes and the looming date, 11/30/25, coming closer, has anyone figured out what is the work around to subscribing to the Webhook API? It seems Blackbaud hasn't announce any work around solutions. I have a few notifications that may stop working after deadline.

Hopefully, Blackbaud will announce something soon.

  • I am now able to receive OPTIONS calls in my HTTP flows, and have been able to resubscribe all of my webhooks to my flows using the new flow URLs.

    The new flow URLs are longer than 255 characters, which causes problems as many webhooks have a 255 character limit on the URL, but luckily Blackbaud does not seem to have that restriction.
