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 Client.

Ready-made or custom UI

  • Ready-made UI: choose WhaleAppSDK. iOS and Android provide native UI; WebTrade can be deployed on a standalone domain for direct user access or embedded in a Broker’s website via iframe.
  • Implement the complete securities UI: use WhaleCore + TradingAPI. WhaleCore supplies market subscriptions, WebSocket connectivity, request signing, token renewal, and other client foundations; TradingAPI supplies account, asset, trading, and related HTTP capabilities.

Authorization boundaries

  • Broker-scoped authorization: Server-to-Server integrations and self-built administration systems use BrokerAPI; requests originate from a Broker-controlled server.
  • Client-scoped authorization: WhaleAppSDK, including WebTrade, WhaleCore, TradingAPI, and OpenAPI access private data as one Client.
  • Broker Developers vs. Developers: a Broker Developer builds the Broker product on the Broker’s behalf; a Developer is a Broker Client building on OpenAPI. The two never share credentials or authorization scope.
Note

WhaleCore has no graphical UI and does not replace TradingAPI. A Broker App implementing the complete securities UI normally combines WhaleCore connection and session foundations with TradingAPI HTTP business endpoints.
