Reporting an Event

Function

This API is used to report custom events. Events with the same time, project_id, event_source, event_name, event_type, sub_event_type, event_state, event_level, event_user, resource_id, and resource_name fields are considered as the same event.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.
