Create (overwrite) variants for a feature in an environment

PUT /api/admin/projects/:projectId/features/:featureName/environments/:environment/variants

This overwrites the current variants for the feature flag in the :featureName parameter for the :environment parameter.

The backend will validate the input for the following invariants:

  • If there are variants, there needs to be at least one variant with weightType: variable
  • The sum of the weights of variants with weightType: fix must be strictly less than 1000 (< 1000)

The backend will also distribute remaining weight up to 1000 after adding the variants with weightType: fix together amongst the variants of weightType: variable

Request

Path Parameters

  • projectId string required
  • featureName string required
  • environment string required

Body

arrayrequired

variantsSchema

  • Array [
  • name string required

    The variants name. Is unique for this feature flag

  • weight number required

    Possible values: <= 1000

    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

    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

  • stickiness string

    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

  • 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
