# Advance Funnel Stage

`POST /v1/notifications/funnel/advance`

## Request

- Base URL: `https://api.mixpeek.com`
- URL: `https://api.mixpeek.com/v1/notifications/funnel/advance`
- Auth: HTTP bearer

Advance the funnel stage from the client side.

Studio calls this when key milestones happen in-browser that the server
cannot observe directly (e.g. first_search executed in the test tab).
Accepts both resource-creation stages and activation funnel stages.

``source`` is optional provenance for the stage being advanced, recorded on
the analytics event so a stage reached two different ways can be counted
separately. It distinguishes a click on sample data from a real upload, and
a search of a sample retriever from a search of the caller's own data, which
the stage name alone cannot. Ignored for resource-creation stages.
