You know that all of the REST API Errors are listed on the documentation site, right? One of the questions I get a lot is around the REST API's 603 Error, and its often in the context of NEW APIs that are released.

When a new REST API is released, you can't simply change the role and add the new API.. you need to..

  1. Create a new role which includes all of the access you'll need including the new APIs
  2. (Optional) Create a new API Only User - Only if the old API user is in use
  3. Create a new Launchpoint Service
  4. Use the new Client ID and Client Secret

Basically, you're repeating the original steps when you first setup your Launchpoint Service. Note all of your existing REST clients will continue to work fine with existing launchpoint services,  This is only when you want to leverage NEW APIs.
