/api/admin/projects/:projectId

In order to access the admin API endpoints you need to identify yourself. You'll need to create an ADMIN token and add an Authorization header using the token.

Available sense Unleash v4.3

In this document we will guide you on how you can work with feature toggles and their configuration. Please remember the following details:

  • All feature toggles exists inside a project.
  • A feature toggle exists across all environments.
  • A feature toggle can take different configuration, activation strategies, per environment.

We will in this guide use HTTPie commands to show examples on how to interact with the API.

Get Project Overview

http://localhost:4242/api/admin/projects/:projectId

This endpoint will give you an general overview of a project. It will return essential details about a project, in addition it will return all feature toggles and high level environment details per feature toggle.

Example Query

http GET http://localhost:4242/api/admin/projects/default Authorization:$KEY

Example response:

{
"description": "Default project",
"features": [
{
"createdAt": "2021-08-31T08:00:33.335Z",
"environments": [
{
"displayName": "Development",
"enabled": false,
"name": "development"
},
{
"displayName": "Production",
"enabled": false,
"name": "production"
}
],
"lastSeenAt": null,
"name": "demo",
"stale": false,
"type": "release"
},
{
"createdAt": "2021-08-31T09:43:13.686Z",
"environments": [
{
"displayName": "Development",
"enabled": false,
"name": "development"
},
{
"displayName": "Production",
"enabled": false,
"name": "production"
}
],
"lastSeenAt": null,
"name": "demo.test",
"stale": false,
"type": "release"
}
],
"health": 100,

Feature Variants

Put variants for Feature Toggle

This overwrites the current variants for the feature toggle specified in the :featureName 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 below 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

Example Query

echo '[
{
"name": "variant1",
"weightType": "fix",
"weight": 650
},
{
"name": "variant2",
"weightType": "variable",
"weight": 123
}
]' | \
http PUT http://localhost:4242/api/admin/projects/default/features/demo/variants Authorization:$KEY

Example response:

HTTP/1.1 200 OK

}
]
}

PATCH variants for a feature toggle

Example Query

echo '[{"op": "add", "path": "/1", "value": {
"name": "new-variant",

"weight": 200
}}]' | \
http PATCH http://localhost:4242/api/admin/projects/default/features/demo/variants Authorization:$KEY

Example Response
