QFEX provides a unified interface for trading and market data via two protocols:

  • gRPC: High performance, strongly typed, HTTP/2 binary protocol.
  • WebSocket: Wider compatibility with legacy systems as well as web support.

Choose the protocol that best fits your integration needs.

Authentication & API Keys

All API calls must be authenticated with an API Key. You can create and manage your keys from your QFEX dashboard:

  2. Navigate to AccountAPI Keys.
  3. Click Create New API Key, provide a descriptive name, and confirm.
  4. Copy the generated key and store it securely — it will only be shown once.
