Arowpay-java-api

Java API implementation and IPNs validation for the cryptocoin payment provider "arowpay.com"

This is a simple API for the arowpay.com platform which is an integrated payment gateway for cryptocurrencies such as Bitcoin , USDT and ethereum. The actual API documentation can be looked up at https://docs.arowpay.com

this is a simple Java wrapper to make it useable from within your Java projects. We have tried to keep it as simple an clean as possible, but however there are some dependencies like slf4j, commons-codec and gson which must be resolved.
