Documented steps
To associate an event with a group, include a $groups property: POST <ingestion host>/i/v0/e/ with properties {"$groups": {"<group_type>": "<group_key>"}} (e.g. {"company": "acme_inc"}).
To set properties on the group itself, send event "$groupidentify" with properties {"$group_type": "company", "$group_key": "acme_inc", "$group_set": {"name": "Acme Inc", "plan": "enterprise"}}.
Ingestion hosts: https://us.i.posthog.com (US) or https://eu.i.posthog.com (EU); auth is the project API key in the body.

Known gotchas
Group analytics requires a paid PostHog plan add-on; group types must exist/are created per project (limited number of group types per project).
$groupidentify with missing $group_type/$group_key silently does nothing useful — include both.
Group properties set via $group_set overwrite previous values for those keys.
For feature flags targeting groups, the same group mapping must be passed in the flags evaluation request body under "groups".
