Schema

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 object[]required
A list of feature toggles with their configuration
Array [
name string required
The unique name of a feature toggle. Is validated to be URL safe on creation
type string
What kind of feature flag is this. Refer to the documentation on feature toggle types for more information
description string nullable
A description of the toggle
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 toggle has been active longer than Unleash expects a toggle of this type to be active
impressionData boolean nullable
Set to true if SDKs should trigger impression events when this toggle is evaluated
project string
Which project this feature toggle belongs to
strategies object[]
Evaluation strategies for this toggle. Each entry in this list will be evaluated and ORed together
Array [
id string
A uuid for the feature strategy
name string required
The name or type of strategy
title string nullable
A descriptive title for the strategy
disabled boolean nullable
A toggle to disable the strategy. defaults to false. Disabled strategies are not evaluated or returned to the SDKs
featureName string
The name or feature the strategy is attached to
sortOrder number
The order of the strategy in the list
segments number[]
A list of segment ids attached to the strategy
constraints object[]
A list of the constraints attached to the strategy. See https://docs.getunleash.io/reference/strategy-constraints
Array [
contextName string required
The name of the context field that this constraint should apply to.
operator string required
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]
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 toggle
weight integer required
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.
stickiness string required
The stickiness to use for distribution of this variant. Stickiness is how Unleash guarantees that the same user gets the same variant every time
payload object
Extra data configured for this variant
type string required
Possible values: [json, csv, string, number]
The type of the value. Commonly used types are string, number, json and csv.
value string required
The actual value of payload
]

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
weightType string

payload object
Extra data configured for this variant
type string required
Possible values: [json, csv, string, number]
The type of the value. Commonly used types are string, number, json and csv.
value string required
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 string required
The name of the context field used to determine overrides
values string[] required
Which values that should be overriden
]
]
dependencies object[]
Feature dependencies for this toggle
Array [
feature string required
The name of the feature we depend on.
enabled boolean
Whether the parent feature should be enabled. When false variants are ignored. true by default.
variants string[]
The list of variants the parent feature should resolve to. Leave empty when you only want to check the enabled status.
]

segments object[]
A list of Segments configured for this Unleash instance
Array [
id number required
The segment's id.
name string
The name of the segment.
constraints object[]required
List of constraints that determine which users are part of the segment

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
project string[] deprecated
Features that are part of these projects are included in this response. (DEPRECATED) - Handled by API tokens
namePrefix string
