SCIM User API Basics

Liferay DXP 2024.Q1+ Beta Feature

Liferay provides a headless API to perform CRUD operations on SCIM users to keep their identity information in sync with your company’s applications. Use the /scim endpoint from the API Explorer to manage SCIM users.

Adding a User

Start a new Liferay DXP instance by running

docker run -it -m 8g -p 8080:8080 liferay/dxp:2024.q1.1

Sign in to Liferay at http://localhost:8080 using the email address [e-mail] and the password test. When prompted, change the password to learn.

Once Liferay is running,

1. Download and unzip SCIM User API Basics.

   curl https://resources.learn.liferay.com/dxp/latest/en/installation-and-upgrades/securing-liferay/developer-guide/liferay-g7y9.zip -O
   

   unzip liferay-g7y9.zip
   

2. Use the cURL script to add a SCIM user in Liferay. On the command line, navigate to the curl folder. Execute the User_POST_ToInstance.sh script.

   ./User_POST_ToInstance.sh
   

   The JSON response shows the addition of a new SCIM user:

   {
      "emails": [
         {
            "type": "default",
            "value": "[e-mail]",
            "primary": true
         }
      ],
      "meta": {
         "created": "2024-03-13T09:53:22Z",
         "location": "http://localhost:8080/o/scim/v1.0/v2/Users/36433",
         "lastModified": "2024-03-13T09:53:23Z",
         "resourceType": "User"
      },
      "schemas": [
         "urn:ietf:params:scim:schemas:core:2.0:User",
         "urn:ietf:params:scim:schemas:extension:liferay:2.0:User"
      ],
      "urn:ietf:params:scim:schemas:extension:liferay:2.0:User": {
         "birthday": "1970-01-01",
         "male": true
      },
      "name": {
         "familyName": "Baker",
         "givenName": "Able"
      },
      "active": true,
      "externalId": "1446cf10-3de9-6e11-dd15-c561de806259",
      "id": "36433",
      "title": "",
      "userName": "able.baker"
   }
   

3. Verify this by opening the Global Menu (), and navigating to Control Panel → Users and Organizations. See that a new user has been added.

   

4. Alternatively, call the REST service using the Java client. Navigate into the java folder and compile the source files:

   javac -classpath .:* *.java
   

5. Run the User_POST_ToInstance class.

   java -classpath .:* User_POST_ToInstance
   

Examine the cURL Command

The User_POST_ToInstance.sh script calls the REST service with a cURL command.

curl \
   "http://localhost:8080/o/scim/v1.0/v2/Users" \
   --data-raw '
      {
         "active": "'true'",
         "emails": [
            {
               "primary": "'true'",
               "type": "default",
               "value": "[e-mail]"
            }
         ],
         "name": {
            "familyName": "Baker",
            "givenName": "Able"
         },
         "userName": "able.baker"
      }' \
   --header "Content-Type: application/scim+json" \
   --request "POST" \
   --user "[e-mail]:learn"

Here are the command’s arguments:

Arguments	Description
"http://localhost:8080/o/scim/v1.0/v2/Users"	The REST service endpoint
--data-raw "{ "active": "'true'", "emails": [ { "primary": "'true'", "type": "default", "value": "[e-mail]" } ], "name": { "familyName": "Baker", "givenName": "Able" }, "userName": "able.baker" }"	The data to post
--header "Content-Type: application/scim+json"	Indicates that the request body format is in JSON and conforms to the SCIM protocol.
--request "POST"	The HTTP method to invoke at the specified endpoint
--user "[e-mail]:learn"	Basic authentication credentials

Note

Basic authentication is used here for demonstration purposes. For production, you should authorize users via OAuth2. See Using OAuth2 to Authorize Users for a sample React application using OAuth2.

Examine the Java Class

The User_POST_ToInstance.java class adds a SCIM user by calling the UserResource service.

public static void main(String[] args) throws Exception {
	UserResource.Builder builder = UserResource.builder();

	UserResource userResource = builder.authentication(
		"[e-mail]", "learn"
	).build();

	userResource.postV2User(
		new User() {
			{
				active = true;
				name = new Name() {
					{
						familyName = "Baker";
						givenName = "Able";
					}
				};
				emails = new MultiValuedAttribute[] {
					new MultiValuedAttribute() {
						{
							primary = true;
							type = "default";
							value = "[e-mail]";
						}
					}
				};
				userName = "able.baker";
			}
		});
}

This class invokes the REST service using only three lines of code:

Line (abbreviated)	Description
UserResource.Builder builder = ...	Get a Builder for generating a UserResource service instance.
UserResource userResource = builder.authentication(...).build();	Use basic authentication and generate a UserResource service instance.
userResource.postV2User(...);	Call the userResource.postV2User method.

Note that the project includes the com.liferay.scim.rest.client.jar file as a dependency. You can find client JAR dependency information for all REST applications in the API explorer in your installation at /o/api (e.g., http://localhost:8080/o/api).

Note

The main method’s comment demonstrates running the class.
