Initializing the SDK

  • Requires API key for your Amplitude project.
  • Initialize in application:didFinishLaunchingWithOptions:

Example Code

[Amplitude instance].defaultTracking.sessions = YES;
[Amplitude instance].initializeApiKey("API_KEY");

Amplitude.instance().defaultTracking.sessions = true;
Amplitude.instance().initializeApiKey("API_KEY");

Configuring the SDK

  • Customize settings such as event upload periods, max batch size, and server URL.

  • Events can include properties for more context.

User Properties
