Manual Session Tracking in RudderStack SDKs
4 minute read
This guide explains the manual session tracking feature available in the supported RudderStack SDKs (JavaScript, Android (Java), iOS (Obj-C), React Native, and Flutter).
Overview
You can use the manual session tracking feature to define the start and end of a user session.
Manual session tracking overrides the automatic session tracking.
RudderStack supports the following manual session tracking methods:
| Method | Parameters | Description |
|---|---|---|
startSession() | - | RudderStack creates a new session and passes the current timestamp as the sessionId if you don't pass any parameter. |
sessionIdLong integer with minimum length of 10 characters. | RudderStack triggers a new user session if you pass a custom sessionId parameter.RudderStack does not recommend using a decimal number as the sessionId. | |
endSession() | - | RudderStack clears the sessionId and ends the session. |
Persistence scope
The following sections list the persistence scope of manual session tracking in the JavaScript and mobile SDKs.
JavaScript
The persistence scope of manual session tracking in the JavaScript SDK does not depend on whether automatic session tracking is enabled.
If you call startSession(), the manual session continues even if you refresh or reopen the web page. To end the session, you must call endSession().
If you identify a user with a newuserIdin an existing session, RudderStack triggers areset()call. This ends the existing session and generates a new one, irrespective of whetherendSession()is called or not.
Mobile SDKs
The persistence scope of manual session tracking in the mobile SDKs (Android (Java), iOS (Obj-C), React Native, and Flutter) depends on whether automatic session tracking is enabled:
- If automatic session tracking is enabled and you call
startSession(), then RudderStack disables automatic session tracking until the app is closed completely. Once you restart the app, the SDKs resume automatic session tracking. - If automatic session tracking is disabled and you call
startSession(), the manual session is active until you end it by callingendSession().
Sample snippets
The following snippets highlight the use of the manual session tracking methods:
rudderanalytics.startSession() // Starts a new user session and automatically assigns a session ID.
rudderanalytics.startSession(sessionId) // Passes a custom session ID while creating a new session.
rudderanalytics.endSession() // Ends the user session and clears the session ID.
The manual session tracking methods in the Android (Java) SDK are available in the following languages:
- Java
- Kotlin
The following snippets highlight the use of the manual session tracking methods:
rudderClient.startSession(); // Starts a new user session and automatically assigns a session ID.
rudderClient.startSession(sessionId); // Passes a custom session ID while creating a new session.
rudderClient.endSession(); // Ends the user session and clears the session ID.
The corresponding Kotlin code is as follows:
// Starts a new user session and automatically assigns a session ID.
rudderClient.startSession()
// Passes a custom session ID while creating a new session.
rudderClient.startSession(sessionId)
// Ends the user session and clears the session ID.
rudderClient.endSession()The manual session tracking methods in the iOS (Obj-C) SDK are available in the following languages:
- Swift
- Objective-C
The following snippets highlight the use of the manual session tracking methods:
RSClient.sharedInstance()?.startSession() // Starts a new user session and automatically assigns a session ID.
RSClient.sharedInstance()?.startSession(sessionId) // Passes a custom session ID while creating a new session.
RSClient.sharedInstance()?.endSession() // Ends the user session and clears the session ID.The corresponding Objective-C code is as follows:
[[RSClient sharedInstance] startSession]; // Starts a new user session and automatically assigns a session ID.
[[RSClient sharedInstance] startSession:sessionId]; // Passes a custom session ID while creating a new session.
[[RSClient sharedInstance] endSession]; // Ends the user session and clears the session ID.// Starts a new user session and automatically assigns a session ID.
rudderClient.startSession();
// Passes a custom session ID while creating a new session.
rudderClient.startSession(sessionId);
// Ends the user session and clears the session ID.
rudderClient.endSession();// Starts a new user session and automatically assigns a session ID.
rudderClient.startSession();
// Passes a custom session ID while creating a new session.
rudderClient.startSession(sessionId);
// Ends the user session and clears the session ID.
