Capture a PostHog Event from a Webhook

Capture a named PostHog event when a webhook is requested.

Setup and use

In Open Flow bind your PostHog project token to the secret Variable POSTHOG_PROJECT_TOKEN in Capture the event. Set the capture URL and the node’s HTTP host allowlist to your PostHog region or self-hosted instance. The example uses the US ingestion host. In n8n configure your PostHog credential and host. Publish or activate one format, then request the webhook URL with an event query parameter.

Behavior

Each GET sends one event with the requested name and the fixed distinct ID n8n. The webhook acknowledges receipt immediately, before the capture result is known. A successful capture HTTP response is an acceptance rather than confirmation that the event was processed. A failed or uncertain request may already have been accepted; check PostHog before retrying. The webhook is unauthenticated, so anyone who can reach it can submit events; protect the URL or add access controls.

Changes to the source

Open Flow uses the PostHog capture HTTP endpoint with the project token supplied as a Variable. The n8n format retains its PostHog node.
