ACP API Endpoints
ACP exposes endpoints for synchronous, async, and batch order submission.
Endpoints
Authentication
Use either header for API key authentication:
Example: Basic Order Submission
Which one to use
All three run the same fan-out, so all three can partially succeed — NetSuite accepts while
fulfillment rejects. Whatever endpoint you use, read the per-target results rather than a top-level
success flag.
Example
Use your source order ID as the Idempotency-Key — a retried submission then replays the original
result instead of creating a duplicate downstream.
