OAuth is an authorization framework that enables third-party applications to use web services. It comes in two forms: OAuth 1.0 and OAuth 2.0, the latter of which replacing and making the former obsolete. OAuth's main use comes in the form of authentication and authorization, hence the "Auth" in its name. These come in the form of credentials that verify a user and application's identity.
In other words, it handles the security part of applications- be they web, desktop or otherwise- interacting with each other and other web services. This is obviously relevant to Google Apps System Access and Authentication, and we'll cover how those two interact now.
OAuth in Google Apps is used to give internal and third-party applicatiosn access to Google APIs. This means applications used by you and your business can take advantage of Google APIs, such as Cloud Monitoring, Google Drive, CustomSearch, and other Google services. Of course, Google Apps already use these services- but enabling OAuth domain key will allow you to enable these features in other applications and clients in your domain.
To enable OAuth, you'll need to head to your Admin Console. From there, go to Security, then Advanced Settings, then Authentication, then Manage OAuth domain key. Now, you'll need to click "Manage client API access" and "Authorize a new API client".
Finally, you can continue to entering your client's name and the API you want it to use. Your vendors should be able to provide the names for the client sites/apps as well as the scope/API it will have to use. If they can't, they'll need to consult Google's guide on the matter.
