List colorado home-rule cities on a registration

List Colorado home-rule cities from sales on this registration's filings. The registration is looked up across every organization your credential owns, so no selector is needed for a known id. Returns 404 if the registration does not exist or is not visible to your credential, so the API never confirms an id exists. A registration that is not Colorado sales tax, or has no matching sales, returns an empty list. Returns 503 when the lookup is unavailable; retry after the Retry-After delay.

Category: Registrations

Path parameters:
registration_id (string, required) - The unique identifier of the registration.

Response statuses: 200, 400, 401, 403, 404, 409, 422, 503
