To enhance MEXC's API user experience, MEXC has upgraded its WebSocket access service. The new access method utilizes Protocol Buffers (Protobuf) serialization, reducing message data size and improving communication efficiency. For details, visit: https://mexcdevelop.github.io/apidocs/spot_v3_en/#websocket-market-streams.
Key Timeline:
On Aug 4, 2025, 06:00 (UTC), MEXC will discontinue V3 WebSocket daily URL service (wss://wbs.mexc.com/ws) for Open API users.
If you are currently using the daily URL, please migrate to the new WebSocket service in advance to avoid any disruption to your trading activities. We apologize for any inconvenience this may cause.
If you encounter any issues during migration or have any API-related requests, feel free to reach out to the MEXC API Telegram group, where our professional technical support team is available 24/7.
MEXC remains committed to providing you with superior products and services.
