ApiController.groovy
A Controller class written in Grails framework that authorizes API callers and fulfill API requests enabled by 3Scale. It is this class written in Groovy that serves all the API request outlined on the left. You may find the code snippet in Groovy useful when integrating with API Proxy - 3Scale. ApiController.groovy:

/**
