# Get a pull request's changed files with unified-diff patches

> Reads the pull request's changed files with their unified-diff patches live from GitHub — patch absent where GitHub gives none, truncated at GitHub's 3000-file cap — pinned to expected_head_sha when given, so a head that moved past it is a 409 head_moved rather than another commit's files. Any member of an owning organization of the pull request — one whose task published or reviewed it, or with a project on its repository — may call it, a viewer included; reading a connected repository is an org right, so no GitHub connection is needed. A pull request that does not exist and one no organization of the caller owns answer the same 404, and omitting org_id while more than one of the caller's organizations owns it is a 422 org_id_required.
