Exness API

Use the Exness API to connect external systems to account data, market data, and trading workflows.

REST + WebSocketSigned API keysOpenAPI source of truth

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.

First milestoneSigned request

GET /v1/configuration/accounts/{account_id}/account
EXN-API-KEY: <EXN_API_KEY>
EXN-IDEMPOTENCY-KEY:
EXN-TIMESTAMP: <unix_ms>
EXN-SIGN-VERSION: 1
EXN-DATA: <base64url_payload>
EXN-SIGN: <base64url_signature>

Get started in 3 steps

1

Prepare Credentials

Gather your Account ID, API Key, and Secret Key. Keep your Secret Key secure locally-never hardcode it or commit it to Git.

2

Resolve Access Point

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.

3

Execute Trades & Streams

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.
