Event and session callbacks

You can register a delegate callback to notify you of the status of event and session tracking. The Adjust SDK uses the optional AdjustDelegate protocol used for the attribution callback.

Add the following delegate callback function for successfully tracked events:

Objective-C

Swift

Javascript

- (void)adjustEventTrackingSucceeded:(ADJEventSuccess *)eventSuccessResponseData {
}

Add the following delegate callback function for failed tracked events:

Objective-C

Swift

Javascript

- (void)adjustEventTrackingFailed:(ADJEventFailure *)eventFailureResponseData {
}

Add the following delegate callback function for successfully tracked sessions:

Objective-C

Swift

Javascript

- (void)adjustSessionTrackingSucceeded:(ADJSessionSuccess *)sessionSuccessResponseData {
}

Add the following delegate callback function for failed tracked sessions:

Objective-C

Swift

Javascript

- (void)adjustSessionTrackingFailed:(ADJSessionFailure *)sessionFailureResponseData {
}

The SDK will call the delegate functions after it tries to send a package to the Adjust backend. You have access to a response data object within the delegate callback. This object contains information about the status of the callback. Here is a summary of the returned properties:

Event properties

Property	Data type	Description
`message`	NSString	The message from the server or the error logged by the SDK.
`timeStamp`	NSString	The timestamp from the Adjust backend.
`adid`	NSString	A unique device identifier provided by Adjust.
`jsonResponse`	NSDictionary	The JSON object with the response from the server.
`eventToken`	NSString	The event token.
`callbackId`	NSString	The custom defined callback ID set on event object.
`willRetry`	BOOL	Returned if the event object failed. Indicates whether there will be an attempt to resend the package at a later time.

Session properties

Property	Data type	Description
`message`	NSString	The message from the server or the error logged by the SDK.
`timeStamp`	NSString	The timestamp from the Adjust backend.
`adid`	NSString	A unique device identifier provided by Adjust.
`jsonResponse`	NSDictionary	The JSON object with the response from the server.
`willRetry`	BOOL	Returned if the session object failed. Indicates whether there will be an attempt to resend the package at a later time.

Note:

If any value is unavailable, it will default to nil.
