POST /api/v1/session/scoped/revoke

Kill a scoped credential before it expires.

Destroys a scoped credential by id and closes the key-server session beneath it.

A revocation that finds nothing answers 404, not 200: a revocation you believe happened and did not is worse than an error you can see.

The 200 means "the credential no longer exists here", which is the part this Gateway can guarantee. Releasing the key-server token is best effort at the session tier, and its failure is counted rather than thrown.

Authentication​

Send the session id as Authorization: Bearer <session id>, and an RFC 9449 DPoP proof in the DPoP header if your session is bound to a key. The two are required together, not as alternatives — see Authenticating and Proving you hold your key.

This surface sets no cookie

There is no session cookie on any response and none is read on any request. Do not set credentials: "include" on a browser fetch.

400​

BAD_REQUEST -- session is absent or empty.

401​

No live session, a DPoP proof that did not verify, or a certificate session whose certificate the key server now refuses.

SESSION_NOT_FOUND -- the credential names no session this Gateway holds. SESSION_EXPIRED -- it aged out. Both carry reauth: true; obtain a new credential rather than retrying.

PROOF_* -- the sender constraint refused. See the DPoP section of this document for the full table; PROOF_MALFORMED is a 400 and PROOF_REPLAY_CACHE_FULL a 503, and the rest are here.

SCOPED_CREDENTIAL_EXPIRED -- a scoped browser credential passed its fixed lifetime. Use does not extend it: an idle timeout would be refreshed by exactly the traffic a stolen handle produces.

CERTIFICATE_REVOKED -- on a session established by certificate login, the key server re-checks the certificate that session was established with on its operations, and it is now named by revocation evidence. detail is the key server's sentence. The Gateway answers this once and then ENDS everything that service holds or minted here -- its sessions, the delegated sessions and the scoped credentials it minted -- so a later operation on any of them is SESSION_NOT_FOUND. Log in with a different certificate.

SSO_SESSION_EXPIRED -- a single-sign-on session (POST /api/v1/session/oidc) reached its lifetime, or was idle past its binding's idle bound; it has been ended. Sign in again.

SENDER_KEY_RETIRED -- the session's registered sender key was rotated out and its overlap has passed (see "The registered service's credential lifecycle"); the session is closed with this answer. SERVICE_REGISTRATION_ENDED -- the registration a service credential was issued under was removed or narrowed on this Gateway; it has ended. Both are final for that credential.

404​

SCOPED_CREDENTIAL_NOT_FOUND -- no live scoped credential has that id. It may have expired on its own, already been revoked, or never existed.

413​

PAYLOAD_TOO_LARGE (retryable: false) -- the request body is larger than this deployment accepts. It was refused before it was parsed, and the connection is closed. Nothing was sent to the key server.

503​

A capacity ceiling or a missing deployment prerequisite. retryable says which.

A scope of session or process names the ceiling that was hit, and the response carries Retry-After.

BUILD_NOT_ADMITTED (scope: process, retryable: true, Retry-After): the key server does not admit this Gateway's client build. Every key-server connection the Gateway opens attests the signed release it runs (TE_RELEASE_MANIFEST) right after it authenticates; while that attestation is refused -- the release is not registered at the key server's code-signing level, the level was raised under it, or the installed files no longer match the signed manifest -- every route but GET /api/v1/health and GET /api/v1/ready answers this, and detail names the cause. It is never a 401 or a 403: no credential or role of the caller's is at fault. The Gateway re-attempts on a timer and recovers without a restart once the key server admits it; GET /api/v1/ready says when.

CAPACITY_UNAVAILABLE (scope: process, retryable: true, Retry-After): this Gateway is serving its maximum number of requests at once, or cannot track another allowance, or (on a certificate login) is recording its maximum of live certificate sessions -- in which case the session the login created has been closed. Nothing else was sent to the key server. See "Rate and capacity limits" above.

Error handling​

Every failure answers JSON carrying at least code and detail. Match on code — detail is written for a human debugging the call and its wording is not part of the contract. See the error model.
