Set up callbacks

Set up callbacks to trigger functions when the SDK sends information to Adjust. You can set up callbacks for sessions and events.

Important:

You must register your callbacks before initializing the SDK.

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 the Adjust backend. 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.

Session data object

Property	Data type	Description
`Message`	String	The message from the server or the error logged by the SDK.
`Timestamp`	String	The timestamp from the Adjust backend.
`Adid`	String	A unique device identifier provided by Adjust.
`jsonResponse`	Dictionary <string, object>	The JSON object with the response from the server.
`WillRetry`	Boolean	Returned if the session object failed. Indicates whether there will be an attempt to resend the package at a later time.

Success callbacks

Set up success callbacks to trigger functions when the SDK measures a session.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setSessionTrackingSucceededCallbackListener(function(sessionSuccess) {
    // Printing all session success properties.
    console.log("Session tracking succeeded!");
    console.log(sessionSuccess.message);
    console.log(sessionSuccess.timestamp);
    console.log(sessionSuccess.adid);
    console.log(sessionSuccess.jsonResponse);
});
//...
Adjust.create(adjustConfig);

Example

In this example, we set up a callback function sessionSuccess and register it as a success callback. The function logs the timestamp at which the SDK measured the session.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setSessionTrackingSucceededCallbackListener(function(sessionSuccess) {
    console.log(sessionSuccess.timestamp);
});
//...
Adjust.create(adjustConfig);

Failure callbacks

Set up failure callbacks to trigger functions when the SDK fails to measure a session.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setSessionTrackingFailedCallbackListener(function(sessionFailure) {
    // Printing all session failure properties.
    console.log("Session tracking failed!");
    console.log(sessionFailure.message);
    console.log(sessionFailure.timestamp);
    console.log(sessionFailure.adid);
    console.log(sessionFailure.willRetry);
    console.log(sessionFailure.jsonResponse);
});
//...
Adjust.create(adjustConfig);

Example

In this example, we set up a callback function sessionFailure and register it as a failure callback. The function logs the session failure message.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setSessionTrackingFailedCallbackListener(function(sessionFailure) {
    console.log(sessionFailure.message);
});
//...
Adjust.create(adjustConfig);

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 the Adjust backend. 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.

Event data object

Property	Data type	Description
`Message`	String	The message from the server or the error logged by the SDK.
`Timestamp`	String	The timestamp from the Adjust backend.
`Adid`	String	A unique device identifier provided by Adjust.
`JsonResponse`	Dictionary <string, object>	The JSON object with the response from the server.
`EventToken`	String	The event token.
`CallbackId`	String	The custom defined callback ID set on event object.
`WillRetry`	Boolean	Returned if the event object failed. Indicates whether there will be an attempt to resend the package at a later time.

Success callbacks

Set up success callbacks to trigger functions when the SDK measures an event.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setEventTrackingSucceededCallbackListener(function(eventSuccess) {
    // Printing all event success properties.
    console.log("Event tracking succeeded!");
    console.log(eventSuccess.message);
    console.log(eventSuccess.timestamp);
    console.log(eventSuccess.eventToken);
    console.log(eventSuccess.callbackId);
    console.log(eventSuccess.adid);
    console.log(eventSuccess.jsonResponse);
});
//...
Adjust.create(adjustConfig);

Example

In this example, we set up a callback function eventSuccess and register it as a success callback. The function logs the timestamp at which the SDK measured the event.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setEventTrackingSucceededCallbackListener(function(eventSuccess) {
    console.log(eventSuccess.timestamp);
});
//...
Adjust.create(adjustConfig);

Failure callbacks

Set up failure callbacks to trigger functions when the SDK fails to measure an event.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setEventTrackingFailedCallbackListener(function(eventFailure) {
    // Printing all event failure properties.
    console.log("Event tracking failed!");
    console.log(eventFailure.message);
    console.log(eventFailure.timestamp);
    console.log(eventFailure.eventToken);
    console.log(eventFailure.callbackId);
    console.log(eventFailure.adid);
    console.log(eventFailure.willRetry);
    console.log(eventFailure.jsonResponse);
});
/...
Adjust.create(adjustConfig);

Example

In this example, we set up a callback function eventFailure and register it as a failure callback. The function logs the event failure message.

Javascript

const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
//...
adjustConfig.setEventTrackingFailedCallbackListener(function(eventFailure) {
    console.log(eventFailure.message);
});
/...
Adjust.create(adjustConfig);
