Context
GitHub recently released a new REST API endpoint in public preview (May 13, 2026) that allows a GitHub App to directly check if it is installed on a specific GitHub Enterprise account and retrieve its matching installation_id.
Previously, checking for enterprise-level installations required apps to perform tedious pagination across the global /app/installations list to find the correct target. This new capability matches existing patterns available for organizations (GET /orgs/{org}/installation), repositories, and users.
Proposed Changes
API Integration: Integrate the new Enterprise installation endpoint (GET /enterprises/{enterprise}/installation or equivalent REST path mapped under the current GitHub API specification version).
Release note: https://github.blog/changelog/2026-05-13-new-enterprise-installation-api-now-in-public-preview/
API Doc: https://docs.github.com/en/enterprise-cloud@latest/rest/apps/apps?apiVersion=2026-03-10#get-an-enterprise-installation-for-the-authenticated-app
