Upsert OAuth Client

← HTTP API reference
View source specification ↗
POST /oauth-clients

Creates a server-identified OAuth client or fully replaces the client named by id. If-Match is required for replacement. Omitted writable metadata is cleared or defaulted; omitted clientSecret preserves the existing value. Idempotent responses are retained for 24 hours.

Required scope

Any authenticated access token

Header parameters

Idempotency-KeystringRequired

Client-chosen key that makes a non-idempotent request retry-safe, following draft-ietf-httpapi-idempotency-key-header. A committed response is stored for 24 hours and replayed for the same principal, operation, key and payload. Missing key returns 400 IDEMPOTENCY_KEY_REQUIRED, a key longer than 255 characters returns 400 IDEMPOTENCY_KEY_INVALID, the same key with a different payload returns 422, and the same key while the first request is still in flight returns 409. Requests rolled back before external provider attempts do not consume the key. Group mutations retain terminal failed responses after provider attempts together with received provider truth; their operation contract defines these replayable outcomes.

minLength: 1

maxLength: 255

If-Matchstring

Required for a full replacement when the request identifies an existing resource. Send that resource's quoted strong etag from its last GET. A missing condition on a replacement returns 428 PRECONDITION_REQUIRED; a stale condition returns 412 PRECONDITION_FAILED. Omit this header when creating a new resource without an id. Wildcards are accepted only where the operation explicitly permits them.

Request body

Returns

200

Stored OAuth client with its current strong etag. Plaintext is present only on creation or explicit secret replacement, including exact request replay.

Response headers

ETagstring

Opaque strong entity tag of the returned resource version. Send it back in `If-Match` on the next mutation of the same resource.

Errors

400 BAD_REQUEST

Invalid request payload

Check the request fields and any validation details, then correct the payload.

401 UNAUTHORIZED

Unauthorized - invalid or missing authentication token

Obtain a valid access token, then retry.

403 FORBIDDEN

Current OAuth client management permission denied.

Check the linked account and its permissions for the device or resource.

404 NOT_FOUND

Client ID does not exist.

Verify the target identifier and that its endpoint or plugin route still exists.

409 IDEMPOTENCY_KEY_IN_FLIGHT

The key is in flight.

Check the device’s current mode or state. Retry only after the conflict is resolved.

412 PRECONDITION_FAILED

The client version is stale.

Inspect the returned code and family and follow the error handling guide.

422 IDEMPOTENCY_KEY_REUSED

The key was reused with a different payload.

Correct the rejected value using the constraints in the error details or request schema.

428 PRECONDITION_REQUIRED

If-Match is required for replacement.

Inspect the returned code and family and follow the error handling guide.

500 INTERNAL

Internal server error

Retry with backoff only when the operation is safe to repeat. Include the error code when reporting persistent failures.
