GitHub REST API Now Enables Code-Based Management of Secret Scanning Custom Patterns

GitHub's July 13, 2026 changelog introduced REST API support for managing secret scanning custom patterns, enabling a configuration-as-code workflow. The approach allows teams to store desired pattern configurations in version control and synchronize them with GitHub's remote state through a structured plan-and-apply process. A safe sync workflow should compare local and remote patterns, generate a diff plan for human review, and require explicit approval before applying any deletions. Security-sensitive fields such as regex definitions must be sourced strictly from GitHub's official API documentation rather than inferred or invented. The system is designed to enforce declarative state, non-destructive defaults, separated credentials, and an auditable apply step rather than replace GitHub's native pattern-testing tools.
