The Challenge

The Challenge: Manual eCommerce Operations & Disconnected Systems

Managing your business on Walmart Marketplace while relying on Epicor E10 as your core ERP often leads to significant operational hurdles. Manual data entry and disconnected processes create inefficiencies, errors, and hinder your ability to scale.

  • Manual order entry from Walmart into Epicor E10 is time-consuming and prone to human error, delaying fulfillment.
  • Lagging inventory updates between Epicor and Walmart lead to overselling, stockouts, and customer dissatisfaction.
  • Product information inconsistencies across systems result in inaccurate listings, missed sales, and brand damage.
  • Complex returns and refund processes require manual reconciliation, impacting financial accuracy and customer experience.
  • Lack of real-time visibility into sales performance and financial data across both platforms makes strategic decision-making difficult.

Epicor E10 & Walmart Marketplace Integration Details

Our iPaaS solution creates a robust, event-driven architecture for seamless data exchange between Epicor E10 and Walmart Marketplace. This section outlines the technical approach to ensure reliable, secure, and efficient integration.

Data Flow Steps

Connect: Securely establish connections to Epicor E10's RESTful APIs and Walmart Marketplace's OAuth 2.0 APIs using dedicated iPaaS connectors.

Configure Triggers: Set up event-driven triggers (webhooks from Walmart for new orders/returns, Epicor BAQ events or custom webhooks for inventory/product changes) or optimized polling intervals.

Design Workflows: Visually design end-to-end integration flows using the iPaaS low-code interface, specifying the sequence of operations (e.g., 'Get Walmart Order' -> 'Map Data' -> 'Create Epicor Sales Order').

Map & Transform Data: Utilize the iPaaS's visual data mapper to define field-level mappings and apply necessary transformations (e.g., currency conversion, unit of measure conversion, custom logic) between Walmart and Epicor entities.

Implement Business Logic: Embed conditional logic, data validation rules, and error handling mechanisms directly within the integration flows.

Deploy & Monitor: Deploy integration flows to production environments and continuously monitor performance, data integrity, and error rates via iPaaS dashboards and alerting systems.

Data Touchpoints

Walmart Marketplace: Order, OrderItem, Item, Inventory, Price, Shipment, Return, Refund, Feed, Customer
Epicor E10: Customer, Sales Order, Part, Invoice, Purchase Order, GL Account, Warehouse

Data Mapping

Key Entities & Intelligent Data Mapping

Seamless data flow between Epicor E10 and Walmart Marketplace relies on accurate mapping of core business entities. Our iPaaS provides robust tools, enhanced by AI, to ensure data consistency and integrity.

Order / Sales Order

Represents a customer's purchase. Walmart's 'Order' is mapped to Epicor's 'Sales Order'.

Epicor E10 Fields

OrderNum (Epicor unique ID) OrderDate CustomerPONum (maps from Walmart purchaseOrderId) ShipToNum (maps from Walmart shippingInfo) OrderQty (per line item) UnitPrice (per line item) PartNum (per line item) OrderHed.CustomerNum (linked to Customer)

Walmart Marketplace Fields

purchaseOrderId (Walmart unique ID) customerOrderId orderDate orderStatus shippingInfo (address, method) orderLines (array of OrderItem) customerEmail customerName

Mapping Notes

Walmart's `purchaseOrderId` is critical for tracking and should map to a unique field in Epicor (e.g., `CustomerPONum` or a custom field). `orderLines` need to be iterated and mapped to Epicor `Sales Order` line items. Customer information may require de-duplication logic.

  4. 3 Epicor E10 `Sales Order` created via `SalesOrderSvc`, triggering inventory allocation.
  5. 4 Fulfillment process (WMS/Epicor) updates `Shipment` details.
  6. 5 iPaaS sends `Shipment` tracking and status back to Walmart API.
  7. 6 Epicor E10 generates `Invoice` and posts to `GL Account` for revenue recognition.

Business Outcome

API Endpoints & Data Logic

Technical details for developers and architects.

Method Endpoint Purpose
POST /api/v1/Ice.BO.SalesOrderSvc/SalesOrders Creates new Sales Orders in Epicor E10 from Walmart orders.
GET, PUT, PATCH /api/v1/Ice.BO.CustomerSvc/Customers Retrieves or updates customer information for synchronization with Walmart order details.
GET, PATCH /api/v1/Ice.BO.PartSvc/Parts Retrieves product master data and updates inventory levels (`OnHandQty`).

Frequently Asked Questions

Common questions about integration implementation, security, and best practices.

General Integration FAQs

▸ What is the best way to integrate Epicor E10 with Walmart Marketplace?
The most robust and scalable approach is to use an iPaaS (Integration Platform as a Service). An iPaaS provides pre-built connectors, visual mapping tools, and orchestration capabilities to seamlessly connect Walmart Marketplace APIs with Epicor E10, automating order-to-cash, inventory sync, and product lifecycle workflows without custom coding.

Inventory Management FAQs

▸ Does this integration support real-time inventory synchronization?
Absolutely. Leveraging Epicor E10's eventing capabilities (e.g., BAQ events or custom webhooks) and Walmart Marketplace's individual item inventory update APIs or bulk feeds, our iPaaS solution enables near real-time inventory synchronization. This prevents overselling and ensures accurate stock levels are always reflected on Walmart.

Performance FAQs

▸ How does the integration handle Walmart Marketplace API rate limits?
Our iPaaS includes built-in features for intelligent API rate limit management. This involves queuing outgoing requests, dynamic throttling with exponential backoff for 429 errors, and prioritizing Walmart's bulk feed APIs for high-volume updates (inventory, price, item creation). This ensures continuous data flow without interruption.

Customization & Development FAQs

▸ Can I use low-code/no-code tools to customize Epicor E10 and Walmart workflows?
Yes, our modern iPaaS platform is designed with low-code/no-code capabilities. This empowers business analysts and operations teams to visually design, deploy, and manage complex integration workflows involving Epicor E10 and Walmart Marketplace, significantly reducing the need for specialized developers and accelerating automation.

AI & Automation FAQs

▸ How does AI enhance this Epicor E10 and Walmart Marketplace integration?
AI augments the integration by providing intelligent mapping suggestions, detecting anomalies in orders or inventory, automating resolution for common data errors, and offering predictive insights for demand forecasting. This reduces manual effort, improves data quality, and enhances proactive decision-making.

Challenges & Solutions FAQs

▸ What are the common challenges addressed by this integration?
This integration addresses challenges such as manual order entry, inventory discrepancies, slow fulfillment, complex product data harmonization, managing API rate limits, and reconciling returns and refunds. The iPaaS centralizes orchestration, data transformation, and error handling to overcome these hurdles.

Security & Compliance FAQs

▸ How do you ensure data security and compliance during integration?
We employ robust security practices: OAuth 2.0/token-based authentication, end-to-end encryption (TLS/SSL) for data in transit and at rest, least-privilege access, secure credential management in a centralized vault, and comprehensive audit trails. We adhere to GDPR, CCPA, and other relevant data privacy regulations.

Returns Management FAQs

▸ Can this integration handle returns and refunds from Walmart Marketplace?
Absolutely. The iPaaS can automate the entire returns workflow, from receiving return notifications from Walmart, creating return authorizations in Epicor E10, to triggering refund processing via your payment gateway, and updating Walmart with the refund status. This streamlines operations and improves customer experience.
