Websocket API on EXMO consists of public and authenticated methods. Public methods allow access to data in relation to trades, tickers and order book changes without authorisation. Authenticated methods require authorisation and allow user access to trades, wallet changes and order changes.

Note:
Public APIs for REST APIs and WebSocket API do not require authorisation, other APIs require authorisation. In addition to authorisation, some Authenticated API methods and EX-CODE API require a request from EXMO Support.
