+## OAuth usage (for Partners)
+If you are using our OAuth service to make API requests on your customer's behalf, and you already got your Access Token as explained in the [OAuth Integration Guide](https://docs.adyen.com/development-resources/oauth/integration/#page-introduction), you can setup your Client like in the following example:
+
+~~~~ruby
+adyen = Adyen::Client.new
+
+adyen.oauth_token = "oauth_token"
+
+~~~~
+
+The APIs available to use through OAuth in this library depend on the [OAuth Scopes](https://docs.adyen.com/development-resources/oauth/scopes/) defined when [Registering your OAuth client](https://docs.adyen.com/development-resources/oauth/integration/#step-1-register-your-client).
