What is WebSocket API?

WebSocket API is a technology that allows you to open a real-time two-way communication session between a user’s software and the server.

The EXMO Websocket API consists of public and authenticated methods.

Public API

Public API methods allow you to receive the following market data in real-time without authorisation on the exchange:

Trades – data on all states of orders since registration.
Ticker – information on any market changes in the trading pair (order completion, buying/selling price change).
Order book changes – data on the top-25 positions and top-400 changes in the order book.

Authenticated API allows authorised traders to obtain information on transactions, changes in wallets and orders in real-time:

User trades – data on all trades associated with the user.
Wallet changes – data on any changes in the wallet balance (deposits, withdrawals, funds reservation in orders, balance changes resulting after transactions).
Orders changes – data on all user limits and stop orders.

In order to connect easily, we have prepared a ready-made code available in the following languages:

More detailed information about the update can be found in the official documentation on Postman.
