System for Cross-domain Identity Management. A REST-based protocol for automating user and group provisioning across identity providers and downstream applications.

SCIM is the reason enterprise buyers can turn on a SaaS tool without building a custom sync, and it is a hard requirement in most B2B procurement above a certain size. Implementations vary widely in practice: group handling, soft delete versus hard delete, and filtering support are where integrations break. Support PATCH, honor `active: false` as a deactivation, and paginate correctly.
