The Paynova API supports all aspects of payment processing for online retailers in Europe. Use the API to create and send invoices, accept payments and issue refunds, and process orders. The API exposes services in both REST and SOAP, and accepts requests in XML, JSON, JSV, CSV, or MessagePack. Authentication is done via HTTP Basic Auth. Paynova API accepts many different payment methods and currency types. See the documentation for a full outline of payment methods/currency types and for extensive information on implementing the API.
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.
