hi,
i had something very similar when attempting to run requests in readyapi! that failed even though the same request with the same creds worked in postman.
i got my request working by adding in an Authorization header parameter into the GET request despite the fact that i could see the Authorization header in the requests raw details.
so what i did.
1.run the GET request
2. check the raw details on the request and copy the Authorization headers value to clipboard.
3.add in a header parm with the name 'Authorization', paste the value from clipboard into the new header's value field.
4. save project and rerun the GET request.
i dont know if this will fix your problem but its analagous to the problem i had and the above fixed the issue for me.
cheers,
richie
