txtNation is a Mobile Billing and SMS Messaging provider. The Payforit API allows developers to bill their users' phones without making them leave the WAP site. The API is a one off payment version of the Payforit system accessed using the txtNation Gateway.
Once the user has chosen to pay for a particular product on the WAP site, developer should pass variables describing the product and transaction to initiate the transaction. These variables are sent with either the GET or POST method.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
