Idempotent API Calls: Designing workflows to prevent duplicate processing of messages in case of retries.

Circuit Breaker Pattern: To prevent cascading failures when one system becomes unavailable.

Data Touchpoints

iPaaS Core Engine: Orchestrates workflows, handles data routing and processing.
Epicor E9 Connector: Facilitates secure communication with Epicor E9 Business Object Services, database, or file systems.
Walmart Marketplace Connector: Provides pre-built API integrations for Walmart's `/v3` endpoints.
Data Transformation Engine: Visual low-code/no-code tools for mapping and transforming data schemas.
Message Queues: For asynchronous processing, buffering requests, and ensuring reliable delivery.
API Gateway/Manager: Handles API authentication, rate limiting, and security policies.
Monitoring & Alerting Module: Centralized dashboards for operational visibility and proactive notifications.
AI/ML Module: For anomaly detection, predictive analytics, and intelligent mapping suggestions.

Data Mapping

Data Entity Mapping

Explore how data flows between systems with intelligent field mapping and transformation logic.

Mapping customer purchases from Walmart Marketplace to sales orders within Epicor E9 for fulfillment and financial tracking.

Epicor E9 Fields

[field, OrderNum],[description, Unique sales order number in Epicor E9.] [field, OrderDate],[description, Date the order was created.] [field, CustomerCustID],[description, Customer ID in Epicor E9.] [field, ShipToNum],[description, Shipping address ID.] [field, TermsCode],[description, Payment terms code.] [field, OrderHedStatus],[description, Overall order status.] [field, BuyerID],[description, Buyer's unique identifier (e.g., Walmart customer email/ID).]

Walmart Marketplace Fields

[field, purchaseOrderId],[description, Walmart's unique ID for the purchase.] [field, customerOrderId],[description, Customer's unique order ID.] [field, orderDate],[description, Date of the order.] [field, orderStatus],[description, Current status of the order (e.g., Created, Acknowledged, Shipped).] [field, shippingInfo.firstName],[description, Recipient's first name.] [field, shippingInfo.lastName],[description, Recipient's last name.] [field, shippingInfo.phone],[description, Recipient's phone number.] [field, shippingInfo.primaryEmail],[description, Recipient's email address.] [field, shippingInfo.postalAddress.address1],[description, Shipping street address line 1.]

Mapping Notes

Walmart's `purchaseOrderId` should map to a custom field in Epicor E9 (e.g., `ExternalRefNum_c`) for traceability. Customer records might need to be created on the fly in Epicor E9 if they don't exist, using `shippingInfo` details. Payment details are generally handled by Walmart; Epicor E9 sales orders will typically be set to 'Prepaid' or 'Credit Card' payment terms, with the actual transaction recorded separately.

Support & Information

Frequently Asked Questions

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

General Integration FAQs

▸ What is the best way to integrate Walmart Marketplace with Epicor E9?
The most effective approach is to use a modern 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 E9, automating order-to-cash, inventory sync, and product lifecycle workflows without custom coding.

Product & Inventory FAQs

▸ Can I automate my Walmart Marketplace product listings and inventory updates from Epicor E9?
Absolutely. With an iPaaS, you can automate product data syndication from Epicor E9 (acting as your PIM/ERP) to Walmart Marketplace, including new listings, attribute updates, and image synchronization. Inventory updates can be near real-time, preventing overselling by syncing stock levels from Epicor E9 or your WMS.

Technical FAQs

▸ How does an iPaaS handle Walmart Marketplace API rate limits?
A robust iPaaS includes built-in features for managing API rate limits. This typically involves intelligent queuing, dynamic throttling, and configurable retry mechanisms with exponential backoff. It ensures that your integration requests are sent to Walmart's APIs at an optimal pace, preventing 429 errors and ensuring continuous data flow.

Error Handling FAQs

▸ What kind of Epicor E9 and Walmart Marketplace errors can an iPaaS help me resolve automatically?
An iPaaS can automate resolution for transient errors (e.g., network issues) through retries. For data-related errors (e.g., invalid SKU from Epicor E9, missing required field for Walmart), an iPaaS can flag them, route them to a dead-letter queue for review, and potentially use AI to suggest or apply corrections based on learned patterns.

Development & Deployment FAQs

▸ Is it possible to integrate Epicor E9 and Walmart Marketplace with low-code/no-code tools?
Yes, modern iPaaS platforms are designed with low-code/no-code capabilities. This allows business analysts and operations teams to visually design, deploy, and manage complex Epicor E9 to Walmart Marketplace integration workflows, reducing the need for specialized developers and accelerating time-to-market for new automations.

AI & Innovation FAQs

▸ How can AI enhance my Epicor E9 and Walmart Marketplace integrations?
AI can augment your integrations by providing capabilities like automated anomaly detection for orders (e.g., fraud) from Walmart, intelligent data mapping suggestions between Walmart and Epicor E9 fields, predictive inventory management, and automated exception handling. This reduces manual effort, improves data quality, and offers proactive insights.

Security & Compliance FAQs

▸ How do I ensure data security and compliance for Epicor E9 and Walmart Marketplace integrations?
A best-practice iPaaS platform ensures data security by encrypting data in transit and at rest, securely storing API credentials (including Epicor E9 access and Walmart OAuth tokens), and providing robust access controls. You should also implement data anonymization in non-production environments and adhere to data retention policies to meet compliance requirements like GDPR and CCPA.

Returns & Refunds FAQs

▸ Can an iPaaS help with Walmart Marketplace returns and refund processing in Epicor E9?
Absolutely. An iPaaS can automate the entire returns workflow, from receiving return notifications from Walmart, creating return authorizations (RMAs) in Epicor E9, to triggering refund processing via your payment gateway, and updating Walmart with the refund status. This streamlines operations and improves customer experience.
