The service provides payment functionality based on an escrow system in which funds are held for distribution when terms of sale are completed, as when a product is delivered. It provides tools for stating and revising offer terms until both parties agree, then it accepts and holds payment until the party paying agrees to release the funds. The neutral third party helps to ensure agreement on terms and fulfillment of both delivery and payment, which encourages trust between parties unfamiliar to one another.
API methods support creating a "Transpact" agreement between contracting parties and confirming fulfillment to allow dispersal of funds or voiding an agreement previously created. Methods also support listing of a party's current and past agreements to allow risk assessment.
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.
