Documented steps
To associate a normal event with a group, add a $groups property to the event payload: properties.$groups = { "company": "company_id_in_your_db" }.
POST it as a normal event to https://us.i.posthog.com/i/v0/e/ (or eu.i.posthog.com) with api_key (project token), event, distinct_id, and properties.$groups.
To create or update a group's own properties, send event "$groupidentify" with properties.$group_type (e.g. "company"), properties.$group_key (unique group id), and properties.$group_set (object of group properties like name, tier).
$groupidentify automatically creates the group type if it doesn't already exist in the project.
Groups are identified via a normal capture-endpoint event ($groupidentify), not a dedicated private-API endpoint — use the project token, not a personal API key.
$group_type and $group_key values are each capped at 400 characters.
Regular events without $groups won't roll up into group-level analytics even if $groupidentify was called separately.
Group analytics is a paid add-on feature — verify it's enabled on your plan if group-based flags/queries come back empty.
