Exness API
Use the Exness API to connect external systems to account data, market data, and trading workflows.
Connect your integration to Exness accounts, trading, and market data.
Start with credentials, resolve the access point for the account, then send signed REST requests or subscribe to WebSocket streams.
Get started in 3 steps
Gather your Account ID, API Key, and Secret Key. Keep your Secret Key secure locally-never hardcode it or commit it to Git.
Send a signed request to GET /v1/trading/access-point?account_id={id} using EXN-* headers and an Ed25519 signature. Use the returned access_point host for all subsequent requests.
Send signed trading requests like POST /v1/trading/accounts/{id}/orders directly to your resolved host using a unique EXN-IDEMPOTENCY-KEY. Connect to WebSockets using the same signed headers to track asynchronous order execution and stream live market data.
Prerequisites
Exness account
You need an Exness platform-based account.
Full KYC

Minimum deposit
You need to meet the minimum deposit requirement for your account type.
Account ID, API Key, and Secret Key
After eligibility is met, create credentials in Key Management and keep the Secret Key secure locally.
Expected result
After the quick start, you should have a signed request working, a confirmed account response, and a clear next path: trading operations or market data subscriptions.
