Ability to publish custom patterns via the REST API [GA] #1348

Value Prop

You can now create, manage, and publish secret scanning custom patterns entirely through the REST API, without ever touching the UI. This lets you integrate custom pattern management into your existing automation workflows, CI/CD pipelines, and infrastructure-as-code tooling. Teams that manage patterns at scale across multiple organizations can now do so programmatically with full API coverage.

Expected Outcome

Completing REST API support for custom pattern publishing removes the last manual step that required UI access, giving security and platform teams a fully scriptable path to managing secret scanning. This enables consistent, repeatable deployments of custom patterns and reduces the toil of managing security policies across large organizations.
