# Get all flags (SDK)

`GET /api/client/features`

Returns the SDK configuration for all feature flags that are available to the provided API key. Used by SDKs to configure local evaluation

## Response `200`

clientFeaturesSchema

- ClientFeaturesSchema — Configuration data for backend SDKs for evaluating feature flags.
  - `version` number, required — A version number for the format used in the response. Most Unleash instances now return version 2, which includes segments as a separate array
  - `features` ClientFeatureSchema[], required — A list of feature flags with their configuration
    - `name` string, required — The unique name of a feature flag. Is validated to be URL safe on creation
    - `type` string — What kind of feature flag is this. Refer to the documentation on [feature flag types](https://docs.getunleash.io/concepts/feature-flags#feature-flag-types) for more information
    - `description` string, nullable — A description of the flag
    - `enabled` boolean, required — Whether the feature flag is enabled for the current API key or not. This is ANDed with the evaluation results of the strategies list, so if this is false, the evaluation result will always be false
    - `stale` boolean — If this is true Unleash believes this feature flag has been active longer than Unleash expects a flag of this type to be active
    - `impressionData` boolean, nullable — Set to true if SDKs should trigger [impression events](https://docs.getunleash.io/concepts/impression-data) when this flag is evaluated

      - `segments` number[] — A list of segment ids attached to the strategy

For more information about the various operators, refer to [the strategy constraint operator documentation](https://docs.getunleash.io/concepts/activation-strategies#constraint-operators).
        - `caseInsensitive` boolean — Whether the operator should be case sensitive or not. Defaults to `false` (being case sensitive).

        - `values` string[] — The context values that should be used for constraint evaluation. Use this property instead of `value` for properties that accept multiple values.
        - `value` string — The context value that should be used for constraint evaluation. Use this property instead of `values` for properties that only accept single values.

        - `name` string, required — The variant name. Must be unique for this feature flag

        - `weightType` 'variable' | 'fix', required — Set to `fix` if this variant must have exactly the weight allocated to it. If the type is `variable`, the weight will adjust so that the total weight of all variants adds up to 1000.

        - `stickiness` string, required — The [stickiness](https://docs.getunleash.io/concepts/feature-flag-variants#variant-stickiness) to use for distribution of this variant. Stickiness is how Unleash guarantees that the same user gets the same variant every time

      - `parameters` ParametersSchema — A list of parameters for a strategy
    - `variants` VariantSchema[], nullable — [Variants](https://docs.getunleash.io/concepts/feature-flag-variants#what-are-variants) configured for this flag
