The E-xact API is a web service that allows third-party applications to process transactions through E-xact's system as well as search and report on transaction records. E-xact is a provider of secure online transaction solutions and service to get payment gateways up and running. The API provides functionality for several types of transactions including standard purchases, tagged transactions, debit transactions and special transactions such as pre-authorization. The API uses both RESTful and SOAP protocol and responses can be formatted in either XML, JSON or CSV.
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.
