## Notes

- All amounts are in smallest currency unit (cents for USD: 1000 = $10.00)
- Most write operations require an `idempotency_key`
- Cursor-based pagination: use `cursor` parameter with value from response
- Timestamps are ISO 8601 format
- Some endpoints require specific OAuth scopes (CUSTOMERS_READ, ORDERS_READ, ITEMS_READ, INVOICES_READ, etc.)
