Use the REST API to Manage User Identities with SCIM 2.0
Where: This feature applies to Lightning Experience and Salesforce Classic in all editions.
How: We added these SCIM endpoints for Salesforce extensions, where salesforce_org_url is the org URL (such as a custom domain) for the user. An asterisk (*) indicates the endpoints that we added with SCIM 2.0.
You can request the capabilities of the Salesforce SCIM implementation using https://salesforce_org_url/services/scim/v2/ServiceProviderConfigs.
Request the properties of a specific user using https://salesforce_org_url/services/scim/v1/Users/userID, where userId is the user’s 18-character org ID.
