The iBilling Client Library is an integration solution (API) for Intrannuity’s iBilling subscription and recurring billing platform. The library enables developers to rapidly add subscription and recurring billing, credit card and ACH payment processing, and account management to their software.  The library provides for minimal developer effort and maximum security. The billing platform utilized by the library provides a free web portal management system (UI built on top of the library) and a set of OLAP based reports that can be integrated into 3rd party software via Web-Services (includes billing breakdown, billing cycle entry/exit, revenue forecasting, etc). All major platforms (Java /.NET /PHP /Ruby /ColdFusion /SOAP) are supported. Code samples with detailed documentation are provided for every supported language and include the most common use cases.
