Are there any payment and eCommerce frameworks that can seamlessly integrate with a REST-based application right out of the box? My server is Java-based, but I've found limited options in this area. I'm open to wrapping my interface with another tool if necessary.
In my application, users should be able to easily subscribe to new services with just one click. Most frameworks don't play nicely with AJAX, which is why I'm searching for alternatives. Perhaps there's a straightforward JS or JAVA solution specifically designed for payment gateways.
Thank you!
