Integration Options

Choose by UI delivery, caller, and authorization subject

First decide whether Whale should supply the graphical UI. Then decide whether the caller represents the Broker institution or one Customer.

Ready-made or custom UI

  • Ready-made UI: choose WhaleApp SDK. iOS and Android provide native UI; WebTrade integrates through a new tab, iframe, or WebView.
  • Implement the complete securities UI: use WhaleCore SDK + Trading API. WhaleCore SDK supplies market subscriptions, WebSocket connectivity, request signing, token renewal, and other client foundations; Trading API supplies account, asset, trading, and related HTTP capabilities.

Authorization boundaries

  • Broker-scoped authorization: Server-to-Server integrations and self-built administration systems use Broker API; requests originate from a Broker-controlled server.
  • Customer-scoped authorization: WhaleApp SDK, including WebTrade, WhaleCore SDK, Trading API, and OpenAPI access private data as one Customer.
  • Broker Developers and Developer Customers: a Broker Developer builds the Broker product; a Developer Customer is a Broker Customer building with OpenAPI. They never share credentials or authorization scope.
