Main APIs

GreenPay's "API first" philosophy means that our partners should be able to access all our data and functionality through APIs. These include POS APIs (local network and cloud), eCommerce APIs, and server APIs (transaction data and terminal/merchant management).

Additional APIs

The JSON-RPC Transport is only to be used if you're not going to use the WebSocket solution. We do urge you to use the WebSocket solution and not this option.
