Deep Dive: Integration Architecture & Data Flow

Our iPaaS provides the core orchestration layer for the First Data and Walmart Marketplace integration. It acts as a central nervous system, managing secure API connectivity, data transformation, workflow automation, and error handling across both platforms and your internal systems.

Data Flow Steps

Secure Connection: Establish authenticated connections to First Data (OAuth 2.0/API Keys with HMAC) and Walmart Marketplace (OAuth 2.0) using iPaaS's secure credential management.

Event Listener/Polling: iPaaS configures listeners for First Data webhooks (e.g., transaction status, chargebacks) and polls Walmart Marketplace APIs (e.g., new orders, returns) at optimized intervals or leverages webhooks if available.

Data Ingestion & Transformation: Raw data from each system is ingested. The iPaaS's visual mapping engine transforms entities like Walmart 'Order' into a canonical 'Sales Order' format, and First Data 'Transaction' into 'Payment Record', ensuring consistency across systems.

Business Logic & Validation: Workflows apply business rules (e.g., fraud checks, inventory allocation logic, tax calculations) and validate data against predefined schemas before proceeding.

Orchestration & Routing: The iPaaS orchestrates the multi-step workflows, routing data to the appropriate endpoints in the target system (e.g., ERP for sales orders, First Data for refunds, Walmart for inventory updates).

Error Handling & Retries: Automated retry mechanisms with exponential backoff handle transient API errors. Persistent errors are logged, generate alerts, and routed to dead-letter queues for investigation.

Status Updates & Reconciliation: Integration flows ensure that status updates (e.g., payment captured, order shipped) are propagated back to the originating system (Walmart) and to the system of record (ERP). Daily settlement reports from First Data are processed for financial reconciliation.

Data Touchpoints

Walmart Marketplace: Orders, Items, Inventory, Price, Shipments, Returns, Seller Account.
First Data: Transactions (Auth, Capture, Refund, Void), Payment Methods, Customers (Vault), Settlement Reports, Chargebacks, Merchant Accounts.
Intermediary (iPaaS): Canonical Order, Payment, Product, Inventory, Refund, Settlement entities.

Data Mapping

Key Entities & Cross-System Data Mapping

Understanding how core business entities map between Walmart Marketplace and First Data (and potentially your ERP) is crucial for a successful integration. Our iPaaS provides a visual canvas and AI assistance to simplify these complex transformations.

Order

The customer's purchase on Walmart Marketplace, which needs to trigger payment processing in First Data and be recorded in the ERP.

First Data Fields

purchaseOrderId (Walmart's unique ID) customerOrderId orderDate orderStatus shippingInfo (name, address, method) orderLines (sku, quantity, price) totalAmount paymentMethod (implied, often tokenized)

Walmart Marketplace Fields

transactionId (First Data's unique payment ID) orderId (often mapped from Walmart's purchaseOrderId) amount currency transactionType (Authorization, Capture, Refund) status (Approved, Declined, Settled) paymentMethodToken processorResponse

Mapping Notes

Walmart's `purchaseOrderId` is critical for cross-referencing payments in First Data and sales orders in the ERP. `orderLines` need to map to ERP product SKUs. `shippingInfo` maps to customer and shipping address in ERP. The payment initiation in First Data is tied to the `totalAmount` of the Walmart order.

Real-time Order Processing & Payment Capture

When a customer places an order on Walmart Marketplace, the iPaaS immediately pulls the order, sends the payment details (tokenized) to First Data for authorization, and upon success, creates a sales order in the ERP. Once shipped, the iPaaS triggers payment capture via First Data and updates Walmart with fulfillment details.

Integration Steps:

  1. 0 Walmart Marketplace: Customer places order.
  2. 1 iPaaS: Polls/Receives new order via Walmart Orders API.
  3. 2 iPaaS: Extracts payment details, initiates authorization via First Data /v1/payments/authorization endpoint.
  4. 3 First Data: Processes authorization, returns status.
  5. 4 iPaaS: If authorized, creates Sales Order in ERP, updates Walmart Order status to 'Acknowledged'.
  6. 5 ERP/WMS: Processes fulfillment, generates shipment details.
  7. 6 iPaaS: Triggers payment capture via First Data /v1/payments/capture endpoint.
  8. 7 iPaaS: Updates Walmart Order with shipment tracking via /v3/orders PUT.

Business Outcome

Instant order processing, accurate payment status, streamlined fulfillment, real-time inventory updates.

Technical Documentation

API Endpoints & Data Logic

Technical details for developers and architects.

Method Endpoint Purpose
POST /v1/payments/token Tokenize card data for secure, PCI-compliant storage and subsequent transactions.
POST /v1/payments/authorization Authorize a payment amount against a tokenized card, holding funds without immediate capture.
POST /v1/payments/capture Capture previously authorized funds for a transaction, moving them from pending to settled.
POST /v1/payments/refund Process a full or partial refund for a captured transaction, requiring the original transaction ID.
POST /v1/payments/void Cancel an authorized but not yet captured transaction, releasing held funds.
GET /v1/settlements/daily Retrieve daily settlement reports for financial reconciliation and GL posting.
GET /v1/payments/status/{transactionId} Query the current status of a specific transaction by its ID.
GET /v1/chargebacks Retrieve active chargeback notifications for dispute management.

⚡ Transformation Logic

  • Schema Harmonization: Convert Walmart's specific order structure (e.g., `purchaseOrderId`, `orderLines`) into a canonical 'Order' schema for internal use and then map to ERP and First Data requirements.
  • Payment Tokenization: Ensure all sensitive card data is tokenized by First Data and only tokens are handled by the iPaaS or stored in the ERP.
  • Address Standardization: Cleanse and standardize customer shipping and billing addresses from Walmart for accurate ERP records and shipping labels.
  • SKU Mapping: Map Walmart Marketplace SKUs to internal ERP product SKUs for inventory and order line item consistency.
  • Status Mapping: Translate status codes from Walmart (e.g., 'Shipped') and First Data (e.g., 'Captured') into corresponding ERP statuses.
  • Financial Derivations: Calculate net deposit from First Data settlement reports, separating sales, refunds, and fees for accurate GL posting.
  • Error Code Translation: Map specific API error codes from First Data and Walmart into actionable internal error messages.

🛡️ Error Handling

  • Payment Authorization Failure: First Data declines a transaction (e.g., insufficient funds). iPaaS updates Walmart order status accordingly and notifies customer service.
  • Inventory Oversell: ERP/WMS reports zero stock, but Walmart still shows availability. iPaaS detects this, updates Walmart, and flags affected orders.
  • API Rate Limit Exceeded: Walmart or First Data API temporarily blocks requests. iPaaS throttles outgoing calls and retries with exponential backoff.
  • Data Validation Error: Walmart product update fails due to missing required attributes. iPaaS logs error, alerts PIM manager, and quarantines invalid data.
