BigCommerce & Opayo (Sage Pay) Integration Details

This integration establishes a robust, event-driven data pipeline between BigCommerce and Opayo, orchestrated by a powerful iPaaS. It ensures secure, real-time synchronization of critical eCommerce and payment data, transforming manual processes into automated workflows.

Data Flow Steps

Connect BigCommerce: Configure the iPaaS connector using BigCommerce OAuth 2.0 or API Keys, granting necessary scopes (e.g., orders, customers, webhooks).

Connect Opayo: Set up the iPaaS connector with Opayo API Key authentication, ensuring secure storage in a secrets manager.

Define Webhooks: Register BigCommerce webhooks (e.g., `ordercreated`, `orderupdated`, `returnstatusupdated`) to trigger iPaaS workflows.

Design Core Workflows: Visually build workflows for Order-to-Cash, Refund Processing, and Customer/Payment Token synchronization.

Map Data Schemas: Use the iPaaS's visual mapping canvas to connect BigCommerce `Order` fields to Opayo `Payment Transaction` fields, and vice-versa.

Implement Transformation Logic: Apply necessary data transformations (e.g., currency conversion, status code mapping, calculated fields) within the iPaaS.

Configure Error Handling & Retries: Set up robust error logging, automated retries with exponential backoff, and dead-letter queues.

Deploy & Monitor: Promote workflows through Dev/QA/Prod environments and monitor performance and health from a centralized dashboard.

Data Touchpoints

BigCommerce `Order` -> Opayo `Payment Transaction`
Opayo `Payment Transaction` Status -> BigCommerce `Order` Status
BigCommerce `Return` / `Order` -> Opayo `Refund`
Opayo `Refund` Status -> BigCommerce `Order` / `Payment` Status
BigCommerce `Customer` -> Opayo `Customer` (for tokenization)
Opayo `Payment Token` -> BigCommerce `Customer` / Subscription System
Opayo `Settlement Batch` -> BigCommerce `Payment` / Accounting System
Opayo `Fraud Indicator` -> BigCommerce `Order` Status / iPaaS Alert

"The integration flow typically starts with a BigCommerce event (e.g., Order Created webhook). This triggers the iPaaS, which then processes the event. For payments, the iPaaS interacts with Opayo's API to authorize and capture funds. Opayo responds with transaction details, which the iPaaS uses to update the BigCommerce order status and potentially push data to an ERP or accounting system. For refunds, the flow reverses, initiating a refund in Opayo and updating BigCommerce/ERP. Daily, the iPaaS pulls Opayo settlement reports for reconciliation."

Data Mapping

Key Entities & Field-Level Mappings

A successful integration hinges on accurate and consistent data mapping between BigCommerce and Opayo entities. Our iPaaS provides a visual mapping canvas to define how key fields are transformed and synchronized, often with AI-assisted suggestions.

Order / Payment Transaction

The core of the eCommerce payment integration. BigCommerce `Order` details are transformed into an Opayo `Payment Transaction` request, and Opayo's `Payment Transaction` status updates the BigCommerce `Order`.

Sage Pay Fields

`transactionId` (Opayo unique ID) `vendorTxCode` (Merchant's transaction ID, often BigCommerce `orderId`) `amount` `currency` `status` (e.g., 'OK', 'PENDING', 'FAILED') `transactionType` (e.g., 'PAYMENT', 'AUTHORISE') `customerEmail` `paymentMethod` `cardType` `createdDate` `fraudIndicator` (risk score, rules triggered)

BigCommerce Fields

`id` (BigCommerce order ID) `customer_id` `status_id` (BigCommerce order status) `date_created` `totalinctax` `currency_code` `payment_status` `billing_address` `shipping_address` `customer_message` `products` (line items)

Mapping Notes

BigCommerce `id` is crucial for Opayo's `vendorTxCode` for traceability. Opayo's `status` must be accurately mapped to BigCommerce `status_id` (e.g., Opayo 'OK' to BigCommerce 'Awaiting Fulfillment'). Tax and shipping amounts often need to be aggregated from BigCommerce line items to form Opayo's total `amount`. Customer email and billing address are passed to Opayo for fraud checks.

Integrating BigCommerce with Opayo via an iPaaS centralizes your integration efforts, provides a single dashboard for monitoring, enables low-code/no-code automation, ensures data harmonization across systems (ERP, CRM, BigCommerce, Opayo), and allows for sophisticated workflow orchestration. This reduces manual effort, improves data accuracy, enhances scalability, and ensures PCI compliance.

Workflows FAQs

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

Real-time Sync FAQs

▸ How does this integration handle BigCommerce orders and Opayo payments in real-time?
The integration leverages BigCommerce's robust webhook system. When an `order_created` event occurs, BigCommerce sends a real-time notification to the iPaaS. The iPaaS immediately processes the order, initiates payment authorization/capture via Opayo's API, and updates the BigCommerce order status, ensuring near-instantaneous payment confirmation and order flow to fulfillment.

Security & Compliance FAQs

▸ Is BigCommerce and Opayo integration PCI DSS compliant?
Yes, Opayo is a PCI DSS Level 1 compliant service provider, and BigCommerce provides a PCI compliant platform. When integrating, it's crucial to ensure your iPaaS and integration methods also adhere to PCI DSS. Using Opayo's tokenization services is a key strategy to minimize your own PCI scope by avoiding direct handling of sensitive card data.

AI Benefits FAQs

▸ How can AI enhance my BigCommerce and Opayo integrations?
AI can augment integrations by providing intelligent fraud detection (identifying suspicious transaction patterns across BigCommerce orders and Opayo payments), automated mapping suggestions in your iPaaS, predictive analytics for cash flow, and smart routing of payment exceptions. This leads to higher data quality, reduced manual intervention, and proactive risk management.

Challenges & Solutions FAQs

▸ What are the common challenges when integrating BigCommerce and Opayo, and how are they solved?
Common challenges include ensuring real-time data synchronization, accurate mapping of transaction statuses and financial codes, managing refunds and chargebacks consistently, and handling high transaction volumes without performance bottlenecks. A modern iPaaS addresses these by centralizing integration management, providing robust data mapping, automated error handling, and scalable architecture.

Data Management FAQs

▸ Can I manage BigCommerce customer data and Opayo payment tokens securely?
Yes. The integration allows for secure synchronization of BigCommerce customer profiles with Opayo payment tokens. Opayo generates secure tokens for card details, which can then be associated with BigCommerce customer IDs in your CRM or subscription system. This avoids storing raw card data, enhancing security and PCI compliance for recurring payments.
