CoinEx

Start with the account and login method

On the CoinEx website, Sign Up accepts an email address and password, followed by email-code confirmation. Google and Apple login are also offered.

An account created through Google or Apple has no separate login password by default. To add one, go to Security Settings → Login Password. If you use Apple's Hide My Email, keep the forwarding address working so that account messages reach you.

Registration is only the login step. Check the account's eligibility, identity requirements and available products before depositing for a particular market.

Match the API module to the task

Spot and futures modules expose prices, trades and order management. Account and asset modules instead cover balances, fee information, transfers and funding history. Subaccount management and transfers have their own functions.

For example, reconciling a deposit and a later trade needs both the funding records and the trading records. A live price stream alone cannot supply that account history. Spot and futures also use distinct WebSocket connection addresses.

What an integration needs to check

Create an API key in the Developer Console, then select the relevant module and endpoint from the reference. Account requests need authentication, including the required headers and a millisecond timestamp.

CoinEx's HTTP guide treats an HTTP 200 response as only part of the success check: the response's own code must also be zero. A program that checks only the HTTP status could miss a rejected operation. The default timestamp window is five seconds, with a configurable alternative.

WebSocket messages are compressed and need decompression before interpretation. After subscribing, inspect the response code before treating later messages as an active feed. These checks matter when connecting an order or balance report that must distinguish live updates from an unsuccessful request.

For transaction costs, consult the account's fee information before placing orders. The API's fee-related functions are useful for account reporting, but they do not make trading or funding free.
