GET /v1/marketplace/ga4/oauth/callback

Authentication

This endpoint is public. It takes no credential and no organisation — it is what our own marketing site and AI answer engines read.

This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.

Try it

Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.

curl -X GET https://api.zinndigital.com/v1/marketplace/ga4/oauth/callback

Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console

Details

⛔ Not called by a client — Google redirects the seller's browser here, so it is unauthenticated by necessity and all of its authority comes from the signed state minted by startMarketplaceListingTrafficConnect. Always a 302 back to the dashboard (/sell?listing=<id>&ga4=connected|cancelled|failed|scope).
