The Continental Clothing API handles HTTP and SOAP calls returning XML or JSON, according to its documentation. It allows its retailers to import the catalog line onto their sites. Continental designs and manufactures eco friendly largely organic clothes, including blank hoodies, Tees, and other garments. These are then sold to retailers who add their own silk screen designs. Among its most interesting customers is HeavyEco, that uses prison labor (and pays for it) to put tattoo impressions on shirts in Eastern Europe, and who donates 50% of profits to NGOs helping orphanages and homeless children. Other customers include the music touring business, and fashion companies looking to create a global presence.
