API Data via Download Tool

[Mario36]

I am trying to fetch data via a Download Tool.

A sample of the URL is below, which works fine on Postman but fails on Alteryx. I am making a GET call and the Authorization token is all good. The Download Tool is erroring out "No Data Received, check the header for details"

I checked the header and everything seems correct.

Sample of the URL : https://api.com/v2/datadownload?AlphaID=ABCDEFG-123456&includeCustomFields=true

The Download Tool fetches data when excluding the custom fields parameters with this code : https://api.com/v2/datadownload?AlphaID=ABCDEFG-12345

But when I add the '&includeCustomFields=true' to the code, it errors out, but works fine on Postman.
