Summary

Updated SCIM API throttle limits description to specify per-API limits and clarify that membership operations in CreateGroup or PatchGroup count toward a separate membership operation throttle limit.

Security assessment

This change clarifies API rate limits, which can impact service availability but does not directly address a security issue or add documentation about security features. It is a routine update to improve accuracy.
