Access OData from Postman RRS feed

  • Question

  • Hello.

    I'm tring to access Project Online OData from Postman (generally, I'll need it in MS Flow HTTP action, but for testing I'm using postman).

    I've tried two ways:

    1. with basic Authentication using user login and password. The result was UnauthorizedAccessException, Access denied. You do not have permission to perform this action or access this resource. User with these credentials have permissions (if i'll login in chrome and use odata URL I'll get information)

    2. I've registered my app /_layouts/15/appregnew.aspx, added permissions /_layouts/15/appinv.aspx, retrieved tenant id, then access token and finally put this token into Authorization header like Bearer <token>. And result was the same - Access denied.

    What is the right way to access OData?

  • Hello,

    The Project Online OData API doesn't support app only auth, it requires a username + password too.

  • I've tried Basic Auth and my username and password.

    As you see - no success. What is the right way?
