GitHub released the Enterprise Installation API in public preview, giving GitHub Apps a direct endpoint to determine if they are installed on an enterprise and to fetch the corresponding installation ID. Previously, developers had to paginate through every installation to locate an enterprise-level one, which was both slow and fragile for apps deployed at scale. The change originated from requests in the GitHub Actions community and simplifies a common pattern for enterprise-grade GitHub App integrations. Teams building internal tooling, CI orchestration, or compliance apps that must identify their enterprise installation context will benefit immediately from the reduced API surface and improved reliability.
