I am using TechJoomla's Common Payment API for my own component. (https://techjoomla.com/common-payment-api)
It seems that the demo component dosen't work. I have a more or less blank component as shown in the image below.
Is it that the API doesn't work with my Joomla version? I am using Joomla! 3.3.6 Stable [ Ember ]. Does anyone have a solution for this?
It also seems that Common Payment API dosen't have a good documentation to look to. I could be wrong, but if anyone does have the link to the documentation, please let me know.
Also, does anyone know what is the most commonly used open source payment api for joomla?
Thanks
