Public API endpoints expose reference data and lookup values used across return-management workflows: country codes, warehouses, service types, status codes, box types, dimension/weight units, fraud reasons, and similar metadata. These responses are stable and tenant-independent — fetch them once during integration setup and cache the results rather than re-fetching on every workflow call. Requests must include x-rr-apikey and x-rr-apitoken headers. See the Authentication section for how to obtain your credentials. Browse the endpoints from the navigation on the left.
