WebSocket Authentication
Endpoint:
wss://ws-feed-pro.btcturk.com- The WebSocket feed provides real-time market data updates for orders and trades.
- The WebSocket feed uses a bi-directional protocol, which encodes all messages as JSON objects. All messages have a type attribute that can be used to handle the message appropriately.
- Please note that new message types can be added at any point in time. Clients are expected to ignore messages they do not support.
- In the form select WebSocket, enter your IP address and submit.
- This action will create public key and a private key to achieve WebSocket login.
