EventMessage

Name	Type
`properties`	`Record<string \| number, any>`
`disableGeoip`	`boolean`
`distinctId`	`string`
`event`	`string`
`groups`	`Record<string, string \| number>`
`flags`	`FeatureFlagEvaluations`
Attach feature flag values evaluated via `posthog.evaluateFlags()` to this event. Prefer this over `sendFeatureFlags` — it guarantees the event carries the exact values the code branched on and avoids a hidden `/flags` request on every capture.
`sendFeatureFlags`	`boolean \| SendFeatureFlagsOptions`
Deprecated: Use the `flags` option with a `FeatureFlagEvaluations` object obtained from `posthog.evaluateFlags()` instead. `sendFeatureFlags` fires a separate `/flags` request on capture and may return different values than the ones the code branched on.
`timestamp`	`Date`
`uuid`	`string`
If provided overrides the auto-generated event UUID. Must be a valid UUID.
