11 Popular Marketplace APIs

Buyers and sellers of the world rejoice! Online marketplaces are the new normal, rapidly replacing fading shopping malls. Multiple sellers can now offer their goods in one sleek, centrally located place, and buyers can search and find desired products from multiple vendors and purchase them with one click, tap, or swipe--from their home, or from anywhere else.

Online marketplaces have digitally transformed the way consumers find coupons, compare prices, discover goods, purchase goods, read or leave reviews, and choose payment, shipping or delivery methods. And sellers can reduce costs, attract new customers, eliminate eCommerce overhead (securing domains, hosting, inventory systems, fulfillment systems, etc.), and leave the heavy lifting to pre-built marketplace software. It's a win-win for everybody (except brick and mortar stores).

Developers wanting to create and enhance applications with marketplace services will need the proper APIs to get the job done.
