SCIM, or System for Cross-domain Identity Management, is an IETF standard that defines an extensible schema mechanism and REST API for managing users and other identity data. SCIM is used by a variety of vendors — including GitHub, Salesforce, Microsoft, Cisco, Sailpoint, and Ping Identity — for a variety of purposes, including user provisioning, directory services, attribute exchange, and more.
The UnboundID SCIM 2 SDK for Java provides a powerful and flexible set of APIs for interacting with SCIM service providers and resources. Use it to build applications and servers that interoperate with SCIM servers such as the PingDirectory Server.
The SCIM 2 SDK consists of the following components:
| Component name | What it is | Who needs it |
|---|---|---|
scim2-sdk-client |
The SCIM 2 client API. | SCIM client developers. |
scim2-ubid-extensions |
Model classes representing UnboundID extensions to the SCIM standard. This component is subject to API changes and should be considered experimental. | SCIM client developers using features specific to UnboundID servers. |
scim2-sdk-server |
Classes for use by SCIM 2 service providers. | SCIM service provider implementers. |
scim2-sdk-common |
Shared model, exception, and utility classes. | Included as a transitive dependency of all of the above. |
The SCIM 2 SDK is available from Maven Central and can be included in your product like any other Maven dependency. Check Maven Central for the latest available version of SCIM 2 SDK dependencies.
For general-purpose clients:
<dependency>
<groupId>com.unboundid.product.scim2</groupId>
<artifactId>scim2-sdk-client</artifactId>
<version>VERSION</version>
</dependency>For clients using UnboundID-specific features:
<dependency>
<groupId>com.unboundid.product.scim2</groupId>
<artifactId>scim2-ubid-extensions</artifactId>
<version>VERSION</version>
</dependency>You may also download SCIM 2 SDK builds from the Releases page.
The UnboundID SCIM 2 SDK requires Java 11 or greater.
The primary point of entry for a client is the ScimService class, which represents a SCIM service provider, such as the PingDirectory Server. This class acts as a wrapper for a JAX-RS client instance, providing methods for building and making requests.
Other classes provide facilities for selecting attributes by path, building query filters, and working with JSON documents. SCIM resources returned from a service provider can either be represented as POJOs or using an API based on the Jackson tree model.

As of version 3.1.0, the SCIM 2 SDK provides the com.unboundid.scim2.common.annotations.Nullable
and com.unboundid.scim2.common.annotations.NotNull annotations for all input parameters, member
variables, and method return values. This is designed to provide insight when invoking SCIM SDK
library methods, help interface with languages like Kotlin (which has built-in null types for
variables), and to help applications become less prone to nullability problems. These annotations
can be leveraged by IDE tools to help validate objects that are given to and received from the SCIM
SDK library. To configure/integrate this into your environment, view the documentation of your IDE
of choice. Some popular choices are linked below:
