Product Events

Events that occur in the Freshcaller product, such as the establishment of a call connection, completion of a call, or transfer of a call, are termed as product events. You can enable product events to trigger apps. To do this, configure event listeners in the server.js file. When a product event occurs, the corresponding event listener invokes a callback method. The app logic in the callback method runs with the help of the event-specific payload passed to the callback method.

Configure Events

To register a product event and the corresponding callback:

  1. From your app’s root directory, navigate to the server.js file.
  2. In the exports block, enter the event, corresponding callback, and callback function definition as follows:
    3. Note: Ensure to enter only one callback method for an event. Multiple events can access the same callback method.
