+## sendaction
+While the view, buy and rate calls are tailored towards a typical eCommerce shop application, easyrec allows for the definition of arbitrary new action types as required by the specific use case. You can use the generic *sendaction* API call to send actions of any type to easyrec. Use the *actiontype* parameter to specify the action. **Note:** action types must be created using the Admin GUI prior to being accepted as valid API calls.
