The v1 docs follow nauthera-server's main branch and its 0.x releases on the way to 1.0, so fields and APIs can still change.

v1

RP-Initiated Logout (OpenID Connect)

Docs version v1 (main)Nauthera is pre-1.0, in a design-partner program

GET/end_session
Session cookieRate limited

Logs the end user out at the OP. If a valid, exactly-registered post_logout_redirect_uri is supplied, the OP redirects the user agent there with state appended; otherwise a logged-out page is shown. The OP never redirects to an unregistered URI.

Authorization

None. This endpoint does not take API credentials.

It reads the browser session from the Cookie header.

The request Cookie header; the interactive login / pending-auth session cookie, and the browser marker a sign-in is recognized by, are read from it.

    The front-channel logout page: one <iframe> per participating relying party, plus a redirect to the post-logout target. Served instead of the 302 only when a participating client registered a frontchannel_logout_uri.

    Delivery through this page is BEST EFFORT and unverifiable — the frames are cross-origin, so the OP can read neither their status nor their body, and §4.1 warns that a browser blocking third-party content will keep the RP from seeing its own cookies at all. Back-Channel Logout 1.0 is the mechanism that actually confirms anything.

    Body

    RFC 9457 (formerly RFC 7807) problem details (application/problem+json). code is a stable machine-readable slug for the problem kind (it mirrors the last path segment of type), so consumers can branch on it without parsing prose. type is https://nauthera.io/problems/<code>, which resolves to the code's runbook: why it happened, who is affected and what to do (RFC 9457 §3.1.1). A problem without a code has about:blank. errors is present on validation failures and lists every offending field.

    • detailstring

    • codeenum

      The kind of problem, as a stable machine-readable slug a client branches on and translates rather than parsing title or detail, which are English prose for logs. A problem whose status says everything the server knows carries no code.

      validation_error is the one code whose message is not a sentence about the code itself: the request failed the schema, and the specifics are the errors list — one entry per offending field — which a form renders on those fields. required and malformed are spelled like two of the per-field violation codes (FieldError.code) but mean something else; the two vocabularies are told apart by position, never by spelling.

      Compatibility: this is a CLOSED enum, with the same cost as AuditAction: a client generated against an older version of this document rejects a problem carrying a code added after it was built. Regenerate on upgrade, or decode the field as a plain string. It is enumerated anyway so that what a client must translate is knowable from the contract alone.
