BloomIdea: Shipping with MRW from Drupal Commerce: no more copy-pasting into the carrier portal

Several of the e-commerce stores we build and run ship with MRW, one of the main carriers in Spain and Portugal. Until recently, shipping an order meant leaving the store: open MRW’s customer portal, retype the customer’s address, print the label, then copy the shipment number back into Drupal so the customer gets a tracking link. Multiply by every order, every day, and add returns, which meant doing the same dance with the addresses swapped.
