The SCIM (System for Cross-Domain Identity Management) standard defines a schema and API to create, read, update, and delete identity and identity-related information on other systems. This standard creates a common language, by which a client system can communicate with many different servers in the same way. SaaS providers (such as Salesforce) and other software vendors are beginning to adopt this standard, and are exposing their identity management interfaces through SCIM.
