Rate an LTL shipment using the SMC3 RateWare XL API

Steps
Obtain a RateWare XL license key from SMC3; the API requires a valid license to access tariff data.
Call the AvailableTariffs method to retrieve the list of small package, LTL, and density-based tariff/rating modules your license key has access to before rating.
Submit a rating request — RateWare XL 2.0 exposes RESTful endpoints (an earlier SOAP interface also exists) — including origin/destination, weight, and NMFC class or density data as required by the selected tariff module.
Parse the returned rate response, which is drawn from SMC3's tariff library covering thousands of carrier tariffs rather than a single generic rate table.
Distinguish RateWare XL (the analytical rating engine) from SMC3's other products such as CarrierConnect XL (carrier-integrated execution/visibility) if your integration also needs live carrier booking or tracking, since these are separate APIs under the same SMC3 platform.
Known gotchas
RateWare XL is a distinct SMC3 product from CzarLite and BillingConnect — confirm which SMC3 product your license actually covers before assuming method or endpoint names carry over between them.
Because rates are density- or class-based depending on the tariff module selected, an incorrect or missing NMFC/density input can return a rate computed on the wrong tariff basis rather than always erroring clearly, so validate the freight classification input before rating.
