`PUT /v1/organizations/{orgId}/projects/{projectId}/flags/{flagId}/environments/{environmentId}`

A whole-config write; the console always sends If-Match with the config's ETag. 400 for an unknown variation or segment, or when a comment is required and missing; 400 snapshot_too_large when the environment's compiled snapshot would exceed 8 MB.

## Authentication

Requires one of the following:

- `apiKey`, http, header `Authorization`
- `oauth`, http, header `Authorization`
- `sessionCookie`, apiKey, in cookie

## Path parameters

- `UpdateFlagConfig.path.orgId` (string, required)
  - format `uuid`
- `UpdateFlagConfig.path.projectId` (string, required)
  - format `uuid`
- `UpdateFlagConfig.path.flagId` (string, required)
  - format `uuid`
- `UpdateFlagConfig.path.environmentId` (string, required)
  - format `uuid`

## Header parameters

- `UpdateFlagConfig.header.If-Match` (string, optional) — The ETag as last read, or *. Without it the write isn't conditional; with a stale one it's 412.

## Request body

_Required._

- `UpdateFlagConfig.defaultServe` (object, required) — Exactly one of variation and rollout.
  - `UpdateFlagConfig.defaultServe.rollout` (object, optional)
    - `UpdateFlagConfig.defaultServe.rollout.weights` (array<object>, required) — Weights sum to exactly 100000 (0.001 % steps).
      - `UpdateFlagConfig.defaultServe.rollout.weights.variation` (string, required) — Lowercase letters, digits, _ and -, starting with a letter or digit; at most 64 characters. Immutable.

      - `UpdateFlagConfig.defaultServe.rollout.weights.weight` (integer, required)
        - min 0; max 100000
    - `UpdateFlagConfig.defaultServe.rollout.bucketBy` (string, optional) — The context attribute to bucket on; targetingKey by default. A context without it gets the first variation.
  - `UpdateFlagConfig.defaultServe.variation` (string, optional) — Lowercase letters, digits, _ and -, starting with a letter or digit; at most 64 characters. Immutable.
    - pattern `^[a-z0-9][a-z0-9_-]{0,63}$`
- `UpdateFlagConfig.enabled` (boolean, required)
- `UpdateFlagConfig.offVariation` (string, required) — Lowercase letters, digits, _ and -, starting with a letter or digit; at most 64 characters. Immutable.
  - pattern `^[a-z0-9][a-z0-9_-]{0,63}$`

  - `UpdateFlagConfig.rules.clauses` (array<object>, required) — ANDed; at most 10.
    - `UpdateFlagConfig.rules.clauses.operator` (unknown, required)
      - one of `"in"`, `"notIn"`, `"contains"`, `"startsWith"`, `"endsWith"`, `"lt"`, `"lte"`, `"gt"`, `"gte"`, `"semverEq"`, `"semverLt"`, `"semverGt"`, `"segmentMatch"`, `"notSegmentMatch"`
    - `UpdateFlagConfig.rules.clauses.values` (array<string | number | boolean>, required) — Strings, numbers or booleans (booleans with in and notIn); segment keys for the segment operators. At most 1,000.
    - `UpdateFlagConfig.rules.clauses.attribute` (string, optional) — A context attribute; dot paths reach nested ones (company.plan). Absent for segmentMatch and notSegmentMatch.
  - `UpdateFlagConfig.rules.id` (string, required)
    - format `uuid`
  - `UpdateFlagConfig.rules.serve` (object, required) — Exactly one of variation and rollout.
    - `UpdateFlagConfig.rules.serve.rollout` (object, optional)

          - min 0; max 100000
      - `UpdateFlagConfig.rules.serve.rollout.bucketBy` (string, optional) — The context attribute to bucket on; targetingKey by default. A context without it gets the first variation.

      - pattern `^[a-z0-9][a-z0-9_-]{0,63}$`
  - `UpdateFlagConfig.rules.description` (string, optional)
    - maxLength 200
- `UpdateFlagConfig.targets` (array<object>, required)
  - `UpdateFlagConfig.targets.values` (array<string>, required)
  - `UpdateFlagConfig.targets.variation` (string, required) — Lowercase letters, digits, _ and -, starting with a letter or digit; at most 64 characters. Immutable.
    - pattern `^[a-z0-9][a-z0-9_-]{0,63}$`
