How ca we test Adobe Acrobat Sign Webhook?

Our webhook has worked fine for years. Last modified in March 2023 (2+ years ago). We just now realized it stopped hitting our server five days ago (April 9, 2026). It’s still “Active” and the URL hasn’t changed and the URL is still valid. I just browsed to it myself and see the attempt in our logs. How can we check it from Adobe’s side? I have a suspicion that they restructured their servers and the request may be coming from a country we block. Are there webhook logs I’m not seeing within Adobe Sign that an admin can view?
