I apologize for mentioning everyone here, but FOSSBilling would benefit from from insight that only the community can provide (specifically regarding payment gateways).
We have 3 known working integrations available and a handful of options that are to the best of our knowledge untested and likely non-functional.
Has anyone tested any of the following payment Gateways inside of FOSSBilling? If so, did it work for you?
AliPay
Interkassa
Onebip
TwoCheckout
WebMoney
If any of these are untested or known to not be working correctly, we will likely remove them from our repository.
None of these integrations have been updated in many years and we can't test or maintain them so removing them will help us get rid of some clutter.
