Adaptive Cards Error: “The remote endpoint returned an error HTTP 401."
Hi All,
When trying to send an adaptive card with Action.Http through Power Automate, the first flow works perfectly, sends the email, I type in the information I need to send back, but when I go to hit submit, it returns the error: “The remote endpoint returned an error HTTP 401.". However, I checked the 2nd flow which receives the Http request on Postman and everything is working on that end as well. I registered my team alias to send emails and that was approved so I am not sure why this is happening. Any help would be much appreciated.
Thanks!

I too faced this problem. It was resolved after adding an empty Authorization header.
The When a HTTP request is received trigger does not expect any credentials, but Outlook automatically sends out a bearer token when you submit an Actionable Message by default. This will lead to a HTTP Unauthorized error message
To avoid this, you must provide a Header with an empty Authorization token inside:

- I faced the same issue. Thanks for the help and saving of time !
- Yes same issue here. I registered everything properly with the originator and everything. I'll see if I can reach out to microsoft.
