Re: 403 Forbidden error when creating Dataset using REST API

 Honestly, I am also a bit confused here. Let me try to provide you further details that might help you identify the problem.

I have a corporate Azure account (ending with "...onmicrosoft.com") that I use for PowerBI as well as the Azure Portal. The portal shows me two directories when I login, AD1 and AD2.

All work is done in the company's globally managed Azure AD1 and this is where the web-app also exists. Following the steps, I then added this web-app to the Azure AD by going to https://dev.powerbi.com/apps, logging in with my onmicrosoft.com account, filling the details in and clicking on the "Register App" button.

However, this registers the web-app in AD2. My concerns here:

1. Is it because AD1 is managed by global admins and I don't have permissions to add apps to it?
2. I can see it listed in the list of applications under AD2. How did it choose AD2 and not AD1 when I clicked the Register App button?

Moving on, I attempted to create the dataset using the snippet provided here with the token received and failed by getting the 403 Forbidden error response.

If I Create a dataset using Apiary, it is created without any problems which is again confusing to me. Do I need to authenticate the web-app first and then use the following?

AuthenticationResult AR = AC.AcquireTokenByAuthorizationCode(code, new Uri(redirectUri), cc);

I'd really appreciate any help you could provide.
