Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Authenticate and call the Transaction API's service discovery endpoint to list available transaction services
Retrieve the schema/definition for the sales-order-creation service to see required and optional fields
Submit a single sales order creation request with customer, ship-to, and line item data matching that schema
For high-volume integrations, batch multiple orders into a bulk create call rather than looping single creates
Inspect the response for per-record success/error status, since bulk calls can partially succeed
Known gotchas
This is unofficial community documentation, not Epicor's own developer docs — field names and required data can differ by P21 version/customization
The Transaction API is stateless and skips some business-rule validation that the Interactive API (which drives the actual P21 UI windows) enforces — some errors only surface when using Interactive API instead
P21 can suffer intermittent session-pool failures under load; documented troubleshooting patterns exist specifically for diagnosing that
