Get a single feature flag

GET 
/api/client/features/:featureName

Gets all the client data for a single flag. Contains the exact same information about a flag as the /api/client/features endpoint does, but only contains data about the specified flag. All SDKs should use /api/client/features

Schema

Schema

name stringrequired
The unique name of a feature flag. Is validated to be URL safe on creation
Example: new.payment.flow.stripe
type string
What kind of feature flag is this. Refer to the documentation on feature flag types for more information
Example: release
description stringnullable
A description of the flag
Example: No variants here
enabled booleanrequired
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
Example: true
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
Example: false
impressionData booleannullable
Set to true if SDKs should trigger impression events when this flag is evaluated
Example: false
project string
Which project this feature flag belongs to
Example: new.payment.flow

strategies

object[]

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

Array [

id string

A uuid for the feature strategy

Example: 6b5157cb-343a-41e7-bfa3-7b4ec3044840

name stringrequired

The name or type of strategy

Example: flexibleRollout

title stringnullable

A descriptive title for the strategy

Example: Gradual Rollout 25-Prod

disabled booleannullable

A toggle to disable the strategy. defaults to false. Disabled strategies are not evaluated or returned to the SDKs

Example: false

featureName string

The name or feature the strategy is attached to

Example: myAwesomeFeature

sortOrder number

The order of the strategy in the list

Example: 9999

segments number[]

A list of segment ids attached to the strategy

Example: [1,2]

constraints

object[]

A list of the constraints attached to the strategy. See https://docs.getunleash.io/reference/strategy-constraints

Array [

contextName stringrequired

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

Example: appName

operator stringrequired

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

Possible values: [NOT_IN, IN, STR_ENDS_WITH, STR_STARTS_WITH, STR_CONTAINS, NUM_EQ, NUM_GT, NUM_GTE, NUM_LT, NUM_LTE, DATE_AFTER, DATE_BEFORE, SEMVER_EQ, SEMVER_GT, SEMVER_LT]

Example: IN

caseInsensitive boolean

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

Default value: false

inverted boolean

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

Default value: false

values string[]

The context values that should be used for constraint evaluation. Use this property instead of value for properties that accept multiple values.

Example: ["my-app","my-other-app"]

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.

Example: my-app

]

variants

object[]

Strategy level variants

Array [

name stringrequired

The variant name. Must be unique for this feature flag

Example: blue_group

weight integerrequired

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

Possible values: <= 1000

weightType stringrequired

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.

Possible values: [variable, fix]

Example: fix

stickiness stringrequired

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

Example: custom.context.field

payload

object

Extra data configured for this variant

type stringrequired

The type of the value. Commonly used types are string, number, json and csv.

Possible values: [json, csv, string, number]

value stringrequired

The actual value of payload

]

parameters

object

A list of parameters for a strategy

property name* string

]

variants

object[]

nullable

Variants configured for this flag

Array [

name stringrequired

The variants name. Is unique for this feature flag

Example: blue_group

weight numberrequired

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

Possible values: <= 1000

weightType string

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

Possible values: [variable, fix]

Example: variable

stickiness string

Stickiness is how Unleash guarantees that the same user gets the same variant every time

Example: custom.context.field

payload

object

Extra data configured for this variant

type stringrequired

The type of the value. Commonly used types are string, number, json and csv.

Possible values: [json, csv, string, number]

value stringrequired

The actual value of payload

overrides

object[]

Overrides assigning specific variants to specific users. The weighting system automatically assigns users to specific groups for you, but any overrides in this list will take precedence.

Array [

contextName stringrequired

The name of the context field used to determine overrides

Example: userId

values string[]required

Which values that should be overriden

Example: ["red","blue"]

]

]

dependencies

object[]

Feature dependencies for this flag

Array [

feature stringrequired

The name of the feature we depend on.

Example: parent_feature

enabled boolean

Whether the parent feature should be enabled. When false variants are ignored. true by default.

Example: false

variants string[]

The list of variants the parent feature should resolve to. Leave empty when you only want to check the enabled status.

Example: ["variantA","variantB"]
