Data Mapping

Data Entity Mapping

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

Order

The central record of a customer's purchase, flowing from Walmart Marketplace to payment processing via Opayo and into an ERP for fulfillment.

Sage Pay Fields

[field, vendorTxCode],[description, Internal order reference passed to Opayo.] [field, amount],[description, Total order value.] [field, currency],[description, Currency of the transaction.] [field, customerEmail],[description, Email for payment/receipt.] [field, billingAddress],[description, Customer's billing address.] [field, shippingAddress],[description, Customer's shipping address.]

Walmart Marketplace Fields

[field, purchaseOrderId],[description, Walmart's unique order ID.] [field, customerOrderId],[description, Customer-facing order ID.] [field, orderDate],[description, Date of order placement.] [field, orderStatus],[description, Current status (e.g., Created, Acknowledged, Shipped).] [field, shippingInfo],[description, Shipping address and method.] [field, orderLines],[description, Details of items purchased.] [field, customerEmail],[description, Customer email (potentially anonymized).] [field, totalPrice],[description, Total value of the order.]

Mapping Notes

Walmart's `purchaseOrderId` or a generated internal ID should be mapped to Opayo's `vendorTxCode` for traceability. `totalPrice` from Walmart maps to Opayo's `amount`. Customer shipping/billing addresses from Walmart are critical for Opayo's fraud checks and for ERP fulfillment. Opayo's transaction `status` should update Walmart's `orderStatus` via iPaaS.

Walmart Order-to-Cash with Opayo Payment & ERP Sync

Automate the complete order lifecycle: A customer places an order on Walmart Marketplace, which triggers a payment authorization via Sage Pay (Opayo). Upon successful payment, the order is automatically created in your ERP for fulfillment, and status updates are sent back to Walmart.

Integration Steps:

  1. 0 Customer places order on Walmart Marketplace.
  2. 1 iPaaS pulls new order from Walmart's /v3/orders endpoint.
  3. 2 iPaaS initiates payment authorization/capture with Opayo via /api/v3/transactions.
  4. 3 Opayo processes payment and returns transaction status.
  5. 4 iPaaS updates order status on Walmart (e.g., 'Acknowledged').
  6. 5 iPaaS creates Sales Order in ERP, linking Opayo transaction ID.
  7. 6 ERP/WMS fulfills order, generates shipment details.
  8. 7 iPaaS pushes shipment details (tracking, carrier) to Walmart's /v3/orders endpoint.
  9. 8 iPaaS updates ERP with final fulfillment status.

Business Outcome

Real-time order processing, faster payment capture, reduced manual data entry, accurate inventory allocation, and improved customer experience with timely updates.

Technical Documentation

API Endpoints & Data Logic

Technical details for developers and architects.

Method Endpoint Purpose
POST /api/v3/transactions Initiate new payment transactions (authorization and capture) for Walmart orders.
POST /api/v3/transactions/{transactionId}/refunds Process refunds for Walmart returns.
GET /api/v3/transactions/{transactionId} Retrieve detailed transaction information for status checks and reconciliation.
POST /api/v3/tokens Create payment tokens for recurring payments (if applicable for future Walmart features) or card-on-file scenarios.

⚡ Transformation Logic

  • Data Normalization: Standardize customer addresses, product SKUs, and currency formats across Walmart, Opayo, and ERP.
  • Status Mapping: Map Opayo transaction statuses (e.g., 'OK', 'NotAuthed') to canonical ERP payment statuses and Walmart order statuses (e.g., 'Acknowledged', 'Shipped').
  • ID Correlation: Ensure Walmart `purchaseOrderId` is consistently mapped to Opayo's `vendorTxCode` and ERP's sales order ID for end-to-end traceability.
  • Value Calculation: Adjust order totals for taxes, shipping, and fees as needed to match payment gateway requirements and ERP accounting standards.
  • Security Masking: Mask or tokenize sensitive customer PII and card data, ensuring only necessary, non-sensitive data is stored or transmitted.
  • Error Formatting: Transform API-specific error codes into human-readable messages for clearer reporting and faster resolution.

🛡️ Error Handling

  • Walmart API Rate Limit Exceeded: iPaaS automatically throttles requests, queues messages, and retries with exponential backoff.
  • Opayo Payment Authorization Failure: iPaaS updates Walmart order status to 'Payment Failed', notifies customer, and logs for review.
  • Data Validation Error (e.g., Invalid SKU): iPaaS routes the message to a dead-letter queue, alerts the product team, and prevents incorrect data from reaching Walmart.
  • Network Connectivity Issues: iPaaS implements circuit breakers to prevent cascading failures and retries connections once resolved.
  • Duplicate Order Submission: Idempotent design ensures that re-processing the same message doesn't create duplicate orders or payments.

Frequently Asked Questions

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

General Integration FAQs

▸ Why integrate Sage Pay (Opayo) with Walmart Marketplace using an iPaaS?
Integrating Opayo with Walmart via an iPaaS centralizes your integration efforts, provides a single dashboard for monitoring, enables low-code/no-code automation, ensures real-time data harmonization across systems (ERP, CRM, eCommerce), and allows for sophisticated workflow orchestration. This reduces manual effort, improves data accuracy, and enhances scalability and PCI DSS compliance for your marketplace sales.

Order & Payment Flow FAQs

▸ How does this integration handle Walmart Marketplace order processing and Opayo payments?
The iPaaS automatically pulls new orders from Walmart Marketplace, initiates payment authorization/capture requests via Opayo's APIs, and then updates the order status back on Walmart and creates a sales order in your ERP upon successful payment. This ensures real-time processing, accurate payment capture, and seamless order fulfillment.

Financial Operations FAQs

▸ Can I automate financial reconciliation between Sage Pay (Opayo) settlements and Walmart sales?
Absolutely. An iPaaS can automatically download Opayo's daily settlement reports, parse the data, and match it against Walmart Marketplace sales transactions recorded in your ERP. Discrepancies can be flagged for review or automatically adjusted, significantly speeding up your financial close process and reducing manual errors.

Security & Compliance FAQs

▸ What are the security considerations, especially regarding PCI DSS compliance?
Opayo is PCI DSS Level 1 compliant. The integration leverages Opayo's hosted payment pages or tokenization services to ensure sensitive cardholder data never touches your systems directly, minimizing your PCI scope. The iPaaS enforces HTTPS/TLS for all communication, securely manages API keys, and adheres to best practices for data encryption and access control, ensuring a highly secure environment.

AI & Automation FAQs

▸ How can AI enhance my Sage Pay (Opayo) and Walmart Marketplace integrations?
AI can significantly augment this integration by providing intelligent fraud detection (analyzing Opayo risk scores and Walmart order patterns), automating data mapping suggestions, validating incoming order data for anomalies, and assisting in categorizing return reasons. This leads to higher data quality, reduced manual intervention, and proactive risk management.

Error Management FAQs

▸ How do I handle errors and failed transactions in this integration?
The iPaaS implements a robust error handling strategy. This includes automated retry mechanisms (with exponential backoff) for transient failures, comprehensive logging of all errors, automated alerts for critical issues, and routing unresolvable failed messages to a 'dead-letter queue' for manual investigation and reprocessing. AI can also assist in diagnosing common error patterns.

Returns & Refunds FAQs

▸ Can this integration manage returns and refunds initiated on Walmart Marketplace?
Yes. When a customer initiates a return on Walmart, the iPaaS detects this, creates an RMA in your ERP, and upon approval/receipt, triggers the refund process via Opayo's refund API. The iPaaS then updates the return status on Walmart Marketplace and ensures your financial records are consistently updated.

Customization & Flexibility FAQs

▸ Is it possible to customize the integration workflows for specific business rules?
Absolutely. The iPaaS offers extensive low-code/no-code capabilities, allowing business users and developers to customize workflows, add conditional logic, map custom fields, and implement specific business rules (e.g., routing orders based on value, applying dynamic pricing) without extensive coding. A sandbox environment supports thorough testing of all customizations.
