Section titled “ Path Parameters ”Request Body
Section titled “ Request Body ”Request body for PUT /api/v1/orgs/{org}/projects/{project}/flags/{flag}/owner. A dedicated
sub-resource for the same reason as expiry: the main flag PUT is a full replace, so an owner field
there would let every client that doesn’t know about owners wipe one. email must belong
to an active member of the organization (case-insensitive).

Headers
Section titled “ Headers ”The maximum number of requests permitted per rate-limit window for this caller.

Bad Request
The frozen public-API error contract. error codes are stable snake_case strings. Wire keys
are frozen snake_case too (error, message, docs_url, fields,
retry_after) — the global camelCase naming policy would otherwise emit
docsUrl/retryAfter, breaking the published spec. !:JsonPropertyName
always wins over the policy, so these are pinned explicitly rather than relying on the
property names already being lowercase for the single-word ones.
did_you_mean, next_actions and connection_id are ADDITIVE optional keys
(null → omitted via the global DefaultIgnoreCondition = WhenWritingNull), so
pre-existing error bodies are byte-for-byte unchanged when they’re absent.
connection_id is present only on the sso_required error: the organization
requires single sign-on, and this credential didn’t come through its identity provider.
connection_id identifies which SSO connection to sign in with.
