A customer is integrating Revenue Cloud with their ecommerce website.

ThePlace Order APIis the appropriate Revenue Management API for creating an order transaction from an external commerce channel at the scale described. The ecommerce site is not merely creating a draft sales record; it is submitting a customer order containing potentially very large numbers of product lines into Revenue Management.

The Place Order operation is designed around the order transaction lifecycle and provides the integration contract required to transfer the customer order into Salesforce. This makes it appropriate for headless or external-channel implementations where order capture occurs outside the standard Salesforce user interface.

Option A, “Create Order,” does not represent the specific API identified by the Revenue Management integration pattern in the supplied source. Option B, Place Sales Transaction, is not the required endpoint for this order-specific scenario.

The scale detail—up to 1,000 products—is important because external commerce integrations often need APIs specifically designed for bulk transaction payloads rather than attempting to create individual Salesforce records through generic object operations.
