SCIM Overview

System for Cross-domain Identity Management (SCIM) offers a standard schema for users and groups (plus other custom entities which can be defined), and a protocol by which these entities can be created, updated, linked and whatnot. The SCIM specification is defined in:

• RFC7643 — Core Schema, defining the format of the information sent to, and received from, the API
• RFC7644 — Protocol, defining the behavior to expect from the API, and how to interact with it
• RFC7642 — Definitions, Overview, Concepts, and Requirements

It allows a Trello user who is an admin of a Trello Enterprise to provision and deprovision users automatically across all the services they use (hosted and cloud-based). As soon as they create a user in their central identity system, a Trello user is created to match.
