WeChat applet preset events and attributes

WeChat Mini Program Preset Events and Attributes

Based on common usage scenarios and to help developers quickly integrate the SDK, the Jiguang Analytics SDK predefines some basic events and attributes. Developers do not need to manually add tracking points; the SDK automatically collects and reports them.
Preset events and preset attributes start with jg_, making them easy to distinguish from custom events and attributes.

Preset Events

All preset events include basic preset attributes. For details, see Preset Event Attributes.

"-" means that the event has only basic preset attributes.
