MRW supports rate card rating. Rate cards must be installed for each EasyPost account; otherwise, the API returns one-cent rates. Contact EasyPost Support for help installing your MRW rate card.

MRW bills customers directly on a bill-on-scan basis. Contact MRW with billing or rate questions.

MRW does not provide predefined packages. Use parcel dimensions and weight when creating shipments.

MRW provides carrier-generated labels in PDF and PNG formats. See the Getting Started Guide for help creating a label.

MRW supports label purchases and one-call buys, which combine shipment creation, rating, and purchase in one request.

Manifesting is not supported.

Cash on delivery amounts must be in EUR, in whole euros, and no greater than 999 EUR. Carrier insurance amounts must be in EUR and are summed across containers. The label date defaults to the current date in Spain when omitted.
