required
Carrier this method draws a live rate from.
Boolean
Whether the merchant has this carrier service turned on. A disabled service is configured but not quoted. Defaults to true, and is omitted only on records predating the flag.
Markup applied to this carrier service specifically, on top of any method-level markup. Omitted when no per-service markup is set.
String!
required
Carrier-specific service code, e.g. ‘fedex_ground’ or ‘usps_priority’. The valid set differs per carrier, so this is not a single closed enum.
