I've been using release definition API on update 3 of TFS 2015 using API version 3.0-preview1 on a prem instance. But since I've started testing on VSTS, I'm getting 404 not found error saying:
Page not found And a long block of HTML.
I'm using powershell to call API which I created using Personal Access Token and alternate credential method: https://fabfiber.vsrm.visualstudio.com/DefaultCollection/ff213d65-d61d-447c-b39d-d16f21b18364/_apis/release/definitions?api-version=3.0-preview.1
Can someone let me know if I am missing something.
Am I doing something wrong here? Any help please.
