Flow action failing with 401 errorIssue API call to the endpoint is not working from the flow. When the same API call is made from postman or REST message, it gives 200 success response.CauseCheck if the user is creating the headers manually in the Rest step.ResolutionIn this scenario, the user was trying to create headers manually. In the Authorisation header, user is using basic instead of Basic. Please note, this headers are case sensitive. Whereas when we test from Postman or REST message, it auto generates the headers and hence they give success response. Note: Kindly avoid generating the headers manually.
