Webhook authorisation and Power Automate

API and Webhooks
1

Hi

I’m trying to use webhooks and Power Automate to automate some business processes. I’ve managed to validate my app successfully, but only after using a custom header, as suggested in this post on this forum: Issue sending webhooks to Microsoft Power Automate (posted in Feb 2025).

However, normal webhook calls are failing, I’m thinking for the same reason because the Zoom logs show this in the response data:

{
  "error": {
    "code": "DirectApiRequestHasMoreThanOneAuthorization",
    "message": "The request has SAS authentication scheme and an additional authorization scheme or internal token scheme. Only one scheme should be used."
  }
}

Any suggestions as to how to over come this?

Thanks in advance

@Admin_NK_SSE did you find a solution for this problem? I’m having the same issue. Power Automate requires SAS authentication/tokens, and Zoom’s validator doesn’t sign or process SAS tokens. If you found a solution, I’d greatly appreciate any help or guidance you can provide.
