With sgcWebSockets 4.1.5 we introduce APIs. There are several implementations based on WebSockets: finance, message publishing, queues... sgcWebSockets implements the most important APIs based on WebSocket protocol. In order to use an API, just attach API component to client and all messages will be handled by API component (only one API component can be attached to a client).

 List of New APIs:

1. Blockchain: Blockchain WebSocket API allows developers to receive Real-Time notifications about new transactions and blocks.

2. Bitfinex: Bitfinex is one of the world's largest and most advanced cryptocurrency trading platform. Users can exchange Bitcoin, Ethereum, Ripple, EOS, Bitcoin Cash, Iota, NEO, Litecoin, Ethereum Classic...

3. Pusher: Pusher is an easy and realiable platform with flexible pub/sub messaging, live user lists, authentication...

APIs can be registered at runtime, just call Method RegisterAPI and pass API component as parameter.
