EMS (Electronic Merchant Systems) is an eCommerce payment gateway. It allows merchants to handle transactions online in realtime or individually through a merchant-operated virtual point of sale terminal (VPOS).
EMS offers 2 APIs that connect users to EMS Merchant Services to streamline transaction processes such as payment, authorizations, settlements, transaction status requests and more. The APIs use the RESTful protocol.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
