SCIM Protocol Explained

The SCIM (System for Cross-domain Identity Management) protocol is an open and standardized method for exchanging and managing user identities across various systems and applications. It uses RESTful APIs and JSON to communicate and represent data, allowing automatic provisioning and deprovisioning of users from identity providers to SaaS apps without manual management. Key components include resource types (User and Group), attributes, schemas, endpoints, and operations based on the CRUD model. Implementing SCIM involves choosing a version, developing API endpoints, securing them, handling advanced features, and testing thoroughly.
