    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 object[]required

    A list of feature flags with their configuration

  • Array [
  • name string required

    The unique name of a feature flag. Is validated to be URL safe on creation

    What kind of feature flag is this. Refer to the documentation on 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

  • impressionData boolean nullable

    Set to true if SDKs should trigger impression events when this flag is evaluated

    Which project this feature flag belongs to

    Evaluation strategies for this flag. Each entry in this list will be evaluated and ORed together

    A uuid for the feature strategy

  • name string required

    The name or type of strategy

  • contextName string required

    The name of the context field that this constraint should apply to.

    The operator to use when evaluating this constraint. For more information about the various operators, refer to the strategy constraint operator documentation.

  • caseInsensitive boolean

    Default value: false

    Whether the operator should be case sensitive or not. Defaults to false (being case sensitive).

  • inverted boolean

    Default value: false

    Whether the result should be negated or not. If true, will turn a true result into a false result and vice versa.

  • 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.

  • variants object[]

    Strategy level variants

  • Array [
  • name string required

    The variant name. Must be unique for this feature flag

    Possible values: <= 1000

    The weight is the likelihood of any one user getting this variant. It is an integer between 0 and 1000. See the section on variant weights for more information

  • weightType string required

    Possible values: [variable, fix]

    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. Refer to the variant weight documentation.

    The stickiness to use for distribution of this variant. Stickiness is how Unleash guarantees that the same user gets the same variant every time

  • ]
  • query object

    A summary of filters and parameters sent to the endpoint. Used by the server to build the features and segments response

  • tag array[]

    Features tagged with one of these tags are included
