Xpayment is a module that allows you to write customised payment gateways, as well as having modular hooking stratum in the module with a second plugin section for modules and responses to invoices.
Complete with Gateway plugins you can easily customise this module for your payment gateway in a few files. There is many benefits to using xpayment as the standard for intergrating payment into your modules. It has a modular plugin system for gateway invoice responses so your module will know when an items has been paid for.
This is the new standard for gateway and payment solutions with XOOPS.
We have a translation project underway this archive from time to time will be patched to include more languages - currently comes with the 1.31 in other languages. - I ask that all that have translated the module for other languages please make the new constants marked at the base of the language file marked for version 1.33 and email me for the final release to the community (Mariane, Yoryo, Voy..)
After testing is complete on the RC's please wait for the final release, but there should be no reason why you can't use this for production.
