CoinPayments is a checkout system for cryptocurrencies such as Bitcoin and Litecoin. Customers click on a link or button on the user's website and get directed to the CoinPayments checkout page to make the payment. Once the transaction is complete, CoinPayments sends the payment to the user, minus transaction fees. Users are notified of every step of the process via Instant Payment Notification (IPN) or polling. The CoinPayments API is designed to allow users to easily integrate the checkout system into their own websites.
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.
