Gets the resolved flag's config in a single resolved environment.
const url = 'https://api.featureflip.io/api/v1/orgs/example/projects/example/flags/example/environments/example';const options = {method: 'GET', headers: {Authorization: '<Authorization>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request GET \ --url https://api.featureflip.io/api/v1/orgs/example/projects/example/flags/example/environments/example \ --header 'Authorization: <Authorization>'There is no single-environment query on the Application side, so this dispatches the same GetFlagEnvironmentConfigurationsQuery as GetAll and finds the resolved environment by id.
Authorizations
Section titled “ Authorizations ”Parameters
Section titled “ Parameters ”Path Parameters
Section titled “ Path Parameters ”Header Parameters
Section titled “ Header Parameters ”Optional. An ETag of this resource. The response is 200 only if it is still the current one; otherwise 412 precondition_failed. * or no header always reads.
Responses
Section titled “ Responses ”OK
Public representation of a flag’s config within a single environment, returned by
GET .../flags/{flag}/environments and GET .../flags/{flag}/environments/{env}.
Drops internal/dashboard-only fields present on FlagEnvironmentConfigurationDto
— Id (an internal row id, not part of the public
contract; EnvironmentId is the addressable key), FeatureFlagId (implicit
in the route), the environment’s name/color/sort-order (dashboard display fields — the public
contract only needs the addressable EnvironmentKey), and Staleness (an
internal analytics signal).
object
Allowed values: SingleVariation, PercentageRollout, TargetedRollout.
A single prerequisite entry on a flag’s per-environment config. Maps 1:1 onto PrerequisiteDto (read side) and PrerequisiteInput (write side).
object
Capability hints: which operations the authenticated caller may perform on this resource, each with allowed + optional reason. Computed from the caller’s role and the resource’s state. Injected at runtime; safe to ignore. Present only on top-level resource responses — nested occurrences (e.g. a rule inside a targeting-config response) do not carry it.
object
One entry in a resource’s _actions block: may the caller perform it, and if not, why.

Section titled “ Headers ”Strong ETag of the resource’s whole body as sent to this caller: it changes whenever anything in the body does. Send it back as If-Match on a PUT.
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.
Authentication is required, or the supplied API token is invalid or expired.
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.
plan_limit is present only on the plan_limit_reached error: which plan cap the
request would have exceeded, so a client can branch on it without parsing message.

The cap behind a plan_limit_reached error. resource is the capped collection

plan is the plan’s wire name, as GET /api/v1/orgs/{org} returns it; max is
the cap. The environment and flag caps are per project.
