GitHub Cloud API endpoints

Overview

Glean uses GitHub's standard REST API to crawl your GitHub Cloud organization, plus the git protocol to clone repository contents. Every permission Glean uses is read-only.

GitHub App permissions

The Glean GitHub App requests the following read-only permissions, grouped by the level they apply to. Organization admins cannot scope them down or expand them.

Metadata	Read-only	Basic repository information (always required)
Pull requests	Read-only	Pull requests, reviews, comments, and diffs
Pages	Read-only	GitHub Pages content for legacy gh-pages sites

Organization

Permission	Access	What it covers
