Technical Integration Details: Epicor P21 and Amazon Fulfillment

The integration leverages a modern, API-first, and event-driven architecture, orchestrated by an iPaaS. This ensures robust, scalable, and secure data exchange between Epicor P21 and Amazon's Selling Partner API (SP-API).

Data Flow Steps

Authentication & Connectivity: Secure OAuth 2.0 (Amazon SP-API) and API Key/OAuth 2.0 (Epicor P21) authentication are configured within the iPaaS, ensuring secure access to both systems.

Event-Driven Triggers: Amazon SP-API Notifications (webhooks) are subscribed for real-time events like new orders or shipment updates. For P21, Change Data Capture (CDC) or scheduled API polling is configured for inventory or financial changes.

Data Retrieval: The iPaaS uses respective APIs (`/orders/v0/orders`, `/api/v1/salesorders`, `/fba/inventory/v1/summaries`, `/api/v1/inventory`, etc.) to fetch relevant data.

Transformation & Mapping: Data is ingested into the iPaaS's visual mapping engine. AI-assisted tools suggest and apply transformations, standardizing data models to a canonical format.

Validation & Business Logic: Pre-defined and AI-inferred business rules, along with data validation checks, are applied to ensure data quality and compliance with target system requirements.

Data Delivery: Transformed and validated data is then sent to the target system via its respective API, respecting rate limits and handling errors gracefully.

Error Handling & Monitoring: Centralized logging, automated retries with exponential backoff, dead-letter queues, and real-time alerts ensure operational resilience and proactive issue resolution.

Data Touchpoints

Epicor P21: Customers, Sales Orders, Inventory Items, Shipments, Invoices (AR), General Ledger Entries, Products.
Amazon Fulfillment: Orders, Products, Inventory Items, Shipments, Returns, Settlement Reports, Financial Events, FBA Inbound Shipments.

"A central iPaaS platform acts as the integration hub. On one side, Epicor P21 (ERP, Accounting, Inventory) connects via its REST APIs. On the other, Amazon Fulfillment (Orders, Inventory, Shipments, Reports) connects via the Amazon Selling Partner API (SP-API) utilizing OAuth 2.0 and webhooks. Data flows bi-directionally for orders, inventory, and product data, while financial data (Settlement Reports) flows from Amazon to P21's GL. Errors are captured and routed via a centralized logging and alerting system within the iPaaS."

eCommerce Order-to-FBA Fulfillment Automation

Automate the entire lifecycle of a new sales order, from its creation on Amazon to fulfillment by FBA and subsequent financial posting in Epicor P21, ensuring real-time data synchronization and minimal manual touchpoints.

Integration Steps:

  1. 0 New order placed on Amazon triggers an event via SP-API Notifications.
  2. 1 iPaaS retrieves full order details from Amazon SP-API `/orders/v0/orders` endpoint.
  3. 2 iPaaS transforms Amazon `Order` data, maps `OrderItems` to Epicor P21 `PartNum`, and creates a new `Sales Order` in P21 via `/api/v1/salesorders`.
  4. 3 P21 acknowledges the `Sales Order` and updates internal inventory allocation.
  5. 4 Amazon FBA fulfills the order. Upon shipment, Amazon sends a `Shipment` notification.
  6. 5 iPaaS retrieves shipment details (`TrackingNumber`, `CarrierCode`) and updates the corresponding `Sales Order` status in P21 via `/api/v1/shipments`.
  7. 6 P21 automatically generates an `AR Invoice` based on the fulfilled `Sales Order`.

Business Outcome

Accelerated order processing, reduced manual entry errors, real-time inventory updates, faster invoicing, and improved customer satisfaction with timely order tracking.

⚡ Transformation Logic

  • Standardization: Normalize data formats (dates, currencies, units of measure).
  • Enrichment: Add data from lookup tables or other systems (e.g., P21 customer details for Amazon buyer info).
  • Aggregation: Combine multiple Amazon `Financial Events` into single P21 `GL Entries`.
  • Splitting: Break down P21 `Sales Order` lines into individual Amazon `OrderItems`.
  • Conditional Formatting: Apply rules like 'if `ItemCondition` is 'Used', then adjust P21 inventory to a specific bin location'.

🛡️ Error Handling

  • Invalid `PartNum`: An Amazon `Order` references a product `SKU` not found in Epicor P21. Solution: Route to dead-letter queue, alert inventory manager, create P21 placeholder item or reject order.
  • Amazon SP-API Rate Limit: Exceeding Amazon's request quotas. Solution: iPaaS automatically throttles and retries with exponential backoff.
  • P21 Database Timeout: Temporary database unavailability. Solution: iPaaS retries the operation after a delay, using circuit breaker logic.
  • Settlement Report Mismatch: Aggregated `GL Entries` from Amazon `Settlement Report` do not balance in P21. Solution: Alert finance, provide granular `Financial Event` logs for investigation.
  • Authentication Token Expiry: Amazon LWA refresh token expires. Solution: iPaaS attempts automatic refresh; if unsuccessful, alerts administrator for manual re-authorization.
