How to make payment system integration with node.js?

Question

Payment systems

I have node + react + redux + express + mongodb spinning. I'm thinking about connecting to a payment aggregator. Are there implementation examples and any documentation to gauge the complexity of this? Is there an open-source module for estimating client's froud points?

Answer 1

It's decided. The integration is quite simple - enough payment systems do not care where I throw POST and GET.
An example API can be found at Yandex-Checkout.
I did not find open-source fraud-detection systems. Most of them are individual. It would be interesting to find a designer of such systems, but 99.9% of them do not exist in the public domain.

Answer 2

there is an inexpensive one for antifraud https://www.maxmind.com/en/solutions/minfraud-services
to make your own antifraud you need data, do you have it?
