How to use the IoT Central REST API to manage users and roles

The IoT Central REST API lets you develop client applications that integrate with IoT Central applications. You can use the REST API to manage users and roles in your IoT Central application.

Every IoT Central REST API call requires an authorization header. To learn more, see How to authenticate and authorize IoT Central REST API calls.

Note

Operations on users and roles are recorded in the IoT Central audit log.

For the reference documentation for the IoT Central REST API, see Azure IoT Central REST API reference.

Tip

You can use Postman to try out the REST API calls described in this article. Download the IoT Central Postman collection and import it into Postman. In the collection, you'll need to set variables such as your app subdomain and admin token.

To learn how to manage users and roles by using the IoT Central UI, see Manage users and roles in your IoT Central application.

Manage roles

The REST API lets you list the roles defined in your IoT Central application. Use the following request to retrieve a list of role IDs from your application:

GET https://{your app subdomain}.azureiotcentral.com/api/roles?api-version=2022-07-31

The response to this request looks like the following example that includes the three built-in roles and a custom role:

{
  "value": [
    {
      "id": "ca310b8d-2f4a-44e0-a36e-957c202cd8d4",
      "displayName": "Administrator"
    },
    {
      "id": "ae2c9854-393b-4f97-8c42-479d70ce626e",
      "displayName": "Operator"
    },
    {
      "id": "344138e9-8de4-4497-8c54-5237e96d6aaf",
      "displayName": "Builder"
    },
    {
      "id": "16f8533f-6b82-478f-8ba8-7e676b541b1b",
      "displayName": "Example custom role"
    }
  ]
}

Manage users

The REST API lets you:

  • List the users in an application
  • Retrieve the details of an individual user
  • Create a user
  • Modify a user
  • Delete a user

List users

Use the following request to retrieve a list of users from your application:

GET https://{your app subdomain}.azureiotcentral.com/api/users?api-version=2022-07-31

The response to this request looks like the following example. The role values identify the role ID the user is associated with:

{
  "value": [
    {
      "id": "91907508-04fe-4349-91b5-b872f3055a95",
      "type": "email",
      "roles": [
        {
          "role": "ca310b8d-2f4a-44e0-a36e-957c202cd8d4"
        }
      ],
      "email": "user1@contoso.com"
    },
    {
      "id": "dc1c916b-a652-49ea-b128-7c465a54c759",

        }
      ],
      "email": "user2@contoso.com"
    },
    {
      "id": "3ab9375e-d2d9-42da-b419-6ae86a938321",

        }
      ],
      "email": "user3@contoso.com"
    },
    {
      "id": "fc5a250b-83fb-433d-892c-e0a144f68c2b",

        }
      ],
      "email": "user4@contoso.com"
    }
  ]
}

Get a user

Use the following request to retrieve details of an individual user from your application:

GET https://{your app subdomain}.azureiotcentral.com/api/users/dc1c916b-a652-49ea-b128-7c465a54c759?api-version=2022-07-31

The response to this request looks like the following example. The role value identifies the role ID the user is associated with:

{
  "id": "dc1c916b-a652-49ea-b128-7c465a54c759",
  "type": "email",
  "roles": [
    {
      "role": "ae2c9854-393b-4f97-8c42-479d70ce626e"
    }
  ],
  "email": "user2@contoso.com"
}

Create a user

Use the following request to create a user in your application. The ID and email must be unique in the application:

PUT https://{your app subdomain}.azureiotcentral.com/api/users/user-001?api-version=2022-07-31

In the following request body, the role value is for the operator role you retrieved previously:

{
  "id": "user-001",
  "type": "email",
  "roles": [
    {
      "role": "ae2c9854-393b-4f97-8c42-479d70ce626e"
    }
  ],
  "email": "user5@contoso.com"
}

The response to this request looks like the following example. The role value identifies which role the user is associated with:

{
  "id": "user-001",
  "type": "email",
  "roles": [
    {
      "role": "ae2c9854-393b-4f97-8c42-479d70ce626e"
    }
  ],
  "email": "user5@contoso.com"
}

You can also add a service principal user which is useful if you need to use service principal authentication for REST API calls. To learn more, see Add or update a service principal user.

Change the role of a user

Use the following request to change the role assigned to user. This example uses the ID of the builder role you retrieved previously:

PATCH https://{your app subdomain}.azureiotcentral.com/api/users/user-001?api-version=2022-07-31

Request body. The value is for the builder role you retrieved previously:
