Metanga is an online billing and subscription payment service. Metanga offers merchants tools and features to bill for and accept payments for services and goods, either one-time payments or recurring subscription billing.
The Metanga API allows developers to access and integrate the functionality of Metanga with other applications. Some example API methods include managing account information, managing and editing product and price information, and managing billing. Public documentation is not available; interested developers should sign up here for more information: http://www.metanga.com/billing-system-demo-request/.
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.
