What this example covers
- Coinbase exchange API JavaScript example.
- Uses the Siebly Coinbase SDK package
coinbase-apiinstead of hand-written HTTP request plumbing. - Source path:
Coinbase/CoinbaseApp/Private/cb-app-private.ts. - Imports SDK symbols including
CBAppClient. - Calls SDK methods such as
depositFunds(),withdrawFunds(),sendMoney(),transferMoney().
How to use this example
- Start here for the specific request or stream pattern, then check the matching SDK guide for install, credentials, and operational notes.
- For private or order-management examples, keep credentials in environment variables or a secret manager. Use read-only keys where possible, and check the execution mode reference before any exchange write path can run.
- Open the repository source when you need the latest committed version: GitHub source file.
