POST/repositories/{repo_id}/access/grants

Give one role to people, service accounts or teams on a repository.

create_repo_access_grants

access:manage
A token needs the access:manage scope: Give, change and revoke access to groups and repositoriesGranted by write_api.Every operation this scope unlocks
Audited · mutation
x-gitmoap-audit: {"kind":"audited","arg":"mutation"}
Quota · members per scope
x-gitmoap-quota: {"kind":"enforced","arg":"members_per_scope"}
Dry run
Takes dry_run.

Names up to 50 subjects, with an optional expiry (in the future, at most a year away) and reason. Callers who can manage access here may call it (Maintainers and above with the built-in roles), and nobody can give a role carrying a permission or rank they do not hold themselves. A subject that already holds the same role is reported as unchanged; one holding a different role is refused. A service account can be given access only at its own group or repository or beneath it, and never as Owner. With dry_run=true the answer says who would gain what, and nothing changes.

Parameters
