}Meta's URL verification (hub.challenge) on the public webhook URL
ING-10 (#193). Reaches ingest only when the query carries hub.challenge; any other GET is the console. For an endpoint whose handshake is meta: with hub.mode=subscribe and a hub.verify_token equal to the endpoint’s verify token (handshake_secret), answers 200 text/plain with hub.challenge. A different token is 403 ‘handshake_failed’. Checked after the endpoint’s disabled state, IP allowlists, suspension and burst limit. Nothing is stored or counted.

}Headers
Optional. If a submission already exists for this tenant with the same key, the request short-circuits with 200 before the monthly quota is charged, so retries are free.
Path Parameters
Workspace (tenant) slug. Must not be one of the reserved roots reserved for app internals (api, admin, stripe, v1, assets, settings, favicon.ico, robots.txt, sitemap.xml, index.html, app.js, styles.css, export.js, portal, brand, trial-info, .well-known, mcp) — those never reach the ingest handler.
Project slug within the workspace.
Webhook slug. This high-entropy slug IS the credential — no key, token or cookie is sent. A disabled webhook answers 503 rather than 404.
Query Parameters
"subscribe"2048Response
The challenge, verbatim.
The response is of type string.
