`GET /repos/{owner}/{repo}/actions/oidc/customization/sub`

- `repo` string, required

## Response `200`

Status response

- OidcCustomSubRepo — Actions OIDC subject customization for a repository
  - `use_default` boolean, required — Whether to use the default template or not. If `true`, the `include_claim_keys` field is ignored.
  - `include_claim_keys` string[] — Array of unique strings. Each claim key can only contain alphanumeric characters and underscores.
  - `use_immutable_subject` boolean — Whether the repository has opted in to the immutable OIDC subject claim format. When `true`, OIDC tokens will use a stable, repository-ID-based `sub` claim. If not set at the repository level, falls back to the organization-level setting.
