Section titled “Path Parameters”Request Body
Section titled “Request Body”Request body for POST .../flags/{flag}/environments/{env}/toggle. Named distinctly from
the dashboard’s own ToggleFlagInEnvironmentRequest
(which uses IsEnabled) — the public field is named Enabled per the phase-3c
contract. Enabled is a NULLABLE bool? deliberately: a non-nullable value
type would bind an omitted/empty body to false with no validation error (ASP.NET’s
implicit-required only covers non-nullable reference types, not value types), silently disabling
the flag. The controller rejects a null Enabled with a validation_failed 400
so the intent is never ambiguous (#1806).

Headers
Section titled “Headers”The maximum number of requests permitted per rate-limit window for this caller.
The number of requests remaining in the current rate-limit window.
The UTC time at which the current rate-limit window resets, as a Unix timestamp in seconds.
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 and next_actions 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.
