Hi,

I have two Flows,

One Flow Send an Adaptive Card to Outlook.
Another Flow is When an Http request is received. (Once Button is Clicked from Adaptive Card in the Mail, response should send to this Flow)

In the Flow, I am sending the adaptive card to Outlook Mail and from the mail if i click on the Button in Adaptive Card, response is not sending to the Flow.
Displaying 401 HTTP Error.

Can help me to resolve this issue.

I have Tried the URL with Postman and i received 401 Unauthorized Error.

Thanks.

When a HTTP request is received - Getting 401 Unauthorized Error

Hello @Hema, have you found a solution to trigger the flow from the adaptive card without using the "Anyone" option?

Hello @rzaneti

I have a use case where I send an email with an Adaptive Card and use a Power Automate flow with a “When an HTTP request is received” trigger to listen for responses.

It works as expected when the HTTP trigger is set to “Anyone”, but when I change the setting to “Any user in my tenant”, the action in the Adaptive Card returns a 401 Unauthorized error.

Unfortunately, our company policy does not allow the “Anyone” option.

Do you know if it’s possible to use the HTTP trigger with this more restrictive setting as a callback from an Adaptive Card in Outlook?

Thank you

When a HTTP request is received - Getting 401 Unauthorized Error

Hi,

You are getting this error because your HTTP request requires an authentication token. You can easily remove this requirement by changing the Who can trigger the flow? property to Anyone. This approach, however, will allow anyone with this URL to make requests that will trigger the flow, which is a potential cybersecurity risk depending on your use case.

If you need to keep the HTTP requests limited to Any user in my tenant, you can follow the steps from this video to generate the authentication token.

Let me know if it works for you or if you need any additional help!
