Set up callbacks to trigger functions when the SDK sends information to Adjust. You can set up callbacks for sessions and events.
Session callbacks
Set up session callbacks to trigger functions when the SDK sends session information. You can create success callbacks and failure callbacks. Success callbacks trigger when the SDK sends information to Adjust’s servers. Failure callbacks trigger when the SDK encounters a problem while sending the information.
Session callbacks have access to a response data object. You can use its properties in your callback function.
Property

A unique device identifier provided by Adjust.
JsonResponse
Dictionary <String, Object>
The JSON object with the response from the server.
WillRetry
Boolean
Indicates whether there will be an attempt to resend a failed package.
Success callbacks
Set up success callbacks to trigger functions when the SDK records a session.
Example
This example shows how to create a callback function sessionSuccess and register it as a success callback. The function logs the timestamp at which the SDK recorded the session.
Failure callbacks
Set up failure callbacks to trigger functions when the SDK fails to record a session.
Example
This example shows how to create a callback function sessionFailure and register it as a failure callback. The function logs the session failure message.
Event callbacks
Set up event callbacks to trigger functions when the SDK sends event information. You can create success callbacks and failure callbacks. Success callbacks trigger when the SDK sends information to Adjust’s servers. Failure callbacks trigger when the SDK encounters a problem while sending the information.
Event callbacks have access to a response data object. You can use its properties in your callback function.
