L-Vin Post API

L-Vin Post is a German service for sending letters to individuals or entire mailing lists. Users submit their letters online, and L-Vin Post then prints, stamps, and mails those letters. L-Vin Post offers a SOAP-based programmatic interface so that users can connect other software to their service. Currently, L-Vin Post only ships letters within Germany, and their website is provided solely in German.
