HTTP call to generate Access Token for Azure Devops

I am getting an access token in the response on the first HTTP call. But when I pass that access token to the password field in the second HTTP call, I get a 401 response (unauthorised).

i know I am close with this. Maybe I need to send a scope or resource parameter in the Body of the first HTTP call?

I do have an App Registration with a client ID and secret with permissions to Azure DevOps.

Please help.

thank you !

Hello @Jondoesflow ,

I'd try to send the token in the request header with Authentication set to "None". That's the approach when calling Graph API - sending the token in the header to handle authentication.

{ "Content-Type": "application/json", "Authorization": "Bearer @{body('HTTP_-_Authenticate')?['access_token']}" }

Now it seems that the request was authenticated, but the url is trying to redirect the request somewhere else. Here I'm unfortunately out of ideas as I never worked with DevOps and I have no idea what's going in there.
