/api/admin/projects/:projectId

info

In order to access the admin API endpoints you need to identify yourself. Unless you're using the none authentication method, you'll need to create an admin token and add an Authorization header using the token.

Fetching Feature Flags​

Available since Unleash v4.3

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

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

This document lists HTTP request data and cURL and HTTPie command examples for all endpoints. Further examples use HTTPie.

Get Project Overview​

Get a project overview
GET <unleash-url>/api/admin/projects/:project-id
Authorization: <API-token>
content-type: application/json

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 flags and high level environment details per feature flag.

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,
  "members": 2,
  "name": "Default",
  "version": 1
}

From the results we can see that we have received two feature flags, demo, demo.test, and other useful metadata about the project.

Feature Variants​

Put variants for Feature Flag​

caution

From 4.21 variants are tied to an environment. Check our Open API docs for the up-to-date docs: https://docs.getunleash.io/reference/api/unleash/features

This endpoint affects all environments at once. If you only want to update a single environment, use #update-variants-per-environment instead.

Create (overwrite) variants for a feature flag in all environments (example data)
PUT <unleash-url>/api/admin/projects/:projectId/features/:featureName/variants
Authorization: <API-token>
content-type: application/json

[
  {
    "name": "variant1",
    "weightType": "fix",
    "weight": 650,
    "payload": {
      "type": "json",
      "value": "{\"key1\": \"value\", \"key2\": 123}"
    },
    "stickiness": "userId",
    "overrides": [
      {
        "contextName": "userId",
        "values": [
          "1",
          "23"
        ]
      }
    ]
  },
  {
    "name": "variant2",
    "weightType": "variable",
    "weight": 123
  }
]

This overwrites the current variants for the feature flag 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,
        "payload": {
          "type": "json",
          "value": "{\"key1\": \"value\", \"key2\": 123}"
        },
        "stickiness": "userId",
        "overrides": [{
          "contextName": "userId",

PATCH variants for a feature flag​

caution

This API documentation is no longer maintained. You should use the OpenAPI docs for this endpoint instead.

This endpoint affects all environments at once. If you only want to update a single environment, use the operation for updating variants per environment instead.

Patch variants for a feature flag in all environments (example data)
PATCH <unleash-url>/api/admin/projects/:projectId/features/:featureName/variants
Authorization: <API-token>
content-type: application/json

[
  {
    "op": "add",
    "path": "/1",
    "value": {
      "name": "new-variant",
      "weightType": "fix",
      "weight": 200
    }
  }
]

Example Query

echo '[{"op": "add", "path": "/1", "value": {
  "name": "new-variant",
  "weightType": "fix",
  "weight": 200
}}]' | \
http PATCH \
http://localhost:4242/api/admin/projects/default/features/demo/variants \
Authorization:$KEY

** Example Response **

{
  "version": "1",
  "variants": [
    {
      "name": "variant2",
      "weightType": "variable",
      "weight": 150
    },
    {
      "name": "new-variant",
      "weightType": "fix",
      "weight": 200
    },
    {
      "name": "variant1",
      "weightType": "fix",
      "weight": 650
    }
  ]
}

Manage project users and roles​

You can add and remove users to a project using the /api/admin/projects/:projectId/users/:userId/roles/:roleId endpoint. When adding or removing users, you must also provide the ID for the role to give them (when adding) or the ID of the role they currently have (when removing).

Add a user to a project​

Add a user to a project (example data)
POST <unleash-url>/api/admin/projects/:projectId/users/:userId/roles/:roleId
Authorization: <API-token>
content-type: application/json

{
  "userId": 25,
  "projectId": "myProject",
  "roleId": "1"
}

This will add a user to a project and give the user a specified role within that project.

URL parameters​

ParameterTypeDescriptionExample value
userIdintegerThe ID of the user you want to add to the project.1
projectIdstringThe id of the project to add the user to."MyCoolProject"
roleIdintegerThe id of the role you want to assign to the new user in the project.7

Responses​

Responses data
200 OK​

The user was added to the project with the specified role. This response has no body.

400 Bad Request​

The user already exists in the project and cannot be added again:

[
  {
    "msg": "User already has access to project=<projectId>"
  }
]

Example query​

The following query would add the user with ID 42 to the MyCoolProject project and give them the role with ID 13.

http POST \
http://localhost:4242/api/admin/projects/MyCoolProject/users/42/roles/13 \
Authorization:$KEY

Change a user's role in a project​

Update a user's role in a project
PUT <unleash-url>/api/admin/projects/:projectId/users/:userId/roles/:roleId
Authorization: <API-token>
content-type: application/json

{
  "userId": 25,
  "projectId": "myProject",
  "roleId": "3"
}

This will change the user's project role to the role specified by :roleId. If the user has not been added to the project, nothing happens.

URL parameters​

ParameterTypeDescriptionExample value
