Hello @ian-ridian! Welcome to the Developer’s Forum and thank you for taking interest in using Coinbase APIs. OAuth2 only supports Sign in with Coinbase API and as of now does not support Exchange/Pro API.
While we can’t offer any specific timeline for the addition of new features. We would like to recommend that you post this in the Feedback Section of the Forum as most new features and improvements to Coinbase come directly from feedback like yours, so it’s very valuable to us. Thank you
