HTTP GET - Flow returns 301 error - Same attempt via Postman returns 200-OK?

Posted on by cdf_pjr 12

Hi,

 

I am building a flow to automate responses to alerts from Microsoft Cloud App Security. As part of the flow I need to perform a HTTP GET request for an alert. This then generates a response in JSON I can then parse to retrieve the information I require.

 

I have crafted the flow but am receiving an error when using the HTTP GET module in flow.

 

The request essentially sends a HTTP GET request to a dynamic URI and sends a header value that contains the relevant API token.

I have performed the operation in postman with a header key of "Authorization" and value of "token <token value>" and this works

 

I have configured the same in the HTTP module in flow which fails every test - if I review the results of the failure I can see the URI is correct (as if I cut and paste the URI used into postman and use it, it works). I cant see the token being sent as the result is sanitised in the flow output, however the header value in the HTTP module is identical (and also works if cut and pasted into postman).

 

Is there any further debugging I can do to get to the bottom of this?

    If I use a bearer token in Postman it fails?

     

    I have seen token used exactly as I am attempting in this video https://youtu.be/-vZucJr6Vck?t=2498 which is what I am trying to replicate.

    Hi @cdf_pjr ,

     

    Authorization token should be in format : Bearer {0} . have you tried doing that ?

     

    Thanks
