HTTP Action - Get Method Authentication

Posted on by Community Power Pla...

Hi Community,

I am trying to use a GET method in a HTTP call to a child flow, but get the following response to the parent flow run:

The request must be authenticated only by Shared Access scheme.

I can get the HTTP request to work if I use the POST method, or if I use the "Run a Child Flow" action with the GET methods specified. So I do have a workaround, but I wanted to see if I can get the parent-child call to work properly with the HTTP action and the GET method.

The limitation on using the GET method with the 'Run a Child Flow" action is that you can't specify query parameters, something I wanted to do in the HTTP call to the child flow to pass a single parameter for the child flow to use.

I suspect it has something to do with the environment set up because I have managed to make this approach work in a different Tenant under my control.

Any suggestions gratefully received.

Cheers, Innes

Hi there,

I went looking around for some answers, and it seems like this fellow had the same issue and the answer was to "copy the URL from the original source".

I guess it somehow retains the old auth information? Unsure, but, seems like it might be helpful? Let us know.

Cheers,

Rhia

Hi Rhia, Thanks for your reply and link. I did try this suggestion, but got the same result. On a completely separate tenant I got the HTTP action to work with a GET, so suspect it's a policy/restriction set on the problem tenant. I've worked around it, but would still like to do it the correct way with a GET as opposed to a POST. Cheers, Innes

I had a similar issue and i changed the HTTP action to the below setup, however you need to make sure to copy the generated link once again as it changed when i updated that option. After that it worked.
