Scalable & Secure Integration Architecture

The recommended integration architecture centers around a modern, cloud-native iPaaS, acting as the intelligent middleware between SAP S/4HANA and Sage Pay (Opayo). This design ensures scalability, resilience, and security, while leveraging event-driven patterns for real-time responsiveness.

Data Flow Steps

API-First, Event-Driven: Utilize S/4HANA OData APIs and Opayo webhooks for real-time data exchange.

Canonical Data Model: Normalize data into a consistent format within the iPaaS before transformation.

Asynchronous Processing: For high-volume or non-real-time tasks (e.g., settlement reconciliation) to prevent system overload.

Circuit Breaker: Protect S/4HANA and Opayo from cascading failures during outages.

Idempotent Operations: Design integration steps to ensure that repeating an operation has the same effect as performing it once, preventing duplicates.

Data Touchpoints

iPaaS Platform: Central hub for orchestration, mapping, and monitoring.
SAP S/4HANA Connectors: Pre-built connectors for OData services.
Sage Pay (Opayo) Connectors: REST API connectors for payment processing and webhooks.
AI/ML Engine: Embedded within iPaaS for auto-mapping, anomaly detection, predictive analytics.
Low-Code/No-Code Designer: Visual interface for workflow creation and customization.
Message Queues: For asynchronous processing and handling high transaction volumes.
Secrets Management: Secure storage for API keys and credentials.
Logging & Monitoring: Centralized system for auditability and performance insights.

"Conceptual Diagram: 'eCommerce/CRM' -> 'iPaaS' (with AI/Low-Code) -> 'SAP S/4HANA' (via OData APIs) AND 'Sage Pay (Opayo)' (via REST APIs & Webhooks). iPaaS contains 'Connectors', 'Data Mappers', 'Business Logic Engine', 'Error Handler', 'Monitoring Dashboard', 'AI Co-pilot'.

Payment Transaction (Opayo) / Payment & Invoice (S/4HANA)

The core financial event representing a payment, authorization, capture, or refund in Opayo, mapped to a Payment and/or Invoice document in SAP S/4HANA.

SAP S/4HANA Fields

[field, BillingDocument],[description, Customer Invoice document number] [field, SupplierInvoice],[description, Supplier Invoice document number] [field, ClearingDocument],[description, Payment clearing document number] [field, Amount],[description, Payment amount] [field, Currency],[description, Currency code] [field, PostingDate],[description, Date of posting] [field, PaymentMethod],[description, Method of payment] [field, BankReference],[description, Bank reference for payment] [field, CompanyCode],[description, SAP Company Code] [field, ReferenceDocument],[description, Reference to original sales order or purchase order]

Sage Pay Fields

[field, transactionId],[description, Unique Opayo transaction identifier] [field, vendorTxCode],[description, Your internal order/invoice reference] [field, amount],[description, Transaction amount] [field, currency],[description, Currency code] [field, status],[description, Transaction status (e.g., OK, DECLINED, PENDING)] [field, transactionType],[description, Type of transaction (e.g., Payment, Refund, Authorise)] [field, customerEmail],[description, Email of the customer] [field, paymentMethod],[description, Payment method used (e.g., Card, PayPal)] [field, cardType],[description, Type of card (e.g., Visa, Mastercard)] [field, createdDate],[description, Date and time of transaction creation]

Mapping Notes

The Opayo `vendorTxCode` is crucial for linking back to SAP S/4HANA's `SalesOrder` or `PurchaseOrderByCustomer` on the Sales Order/Invoice or `ReferenceDocument` on the Payment. Opayo `transactionId` should be stored in S/4HANA for auditability and refund processing. Opayo `status` needs careful mapping to S/4HANA's payment status or clearing indicators. AI can assist in suggesting optimal mappings for transaction types and statuses.

Integration Use Cases

Explore how the integration behaves in real business scenarios, with clearly defined steps, outcomes, and execution patterns.

eCommerce Order-to-Cash with Opayo & S/4HANA

Seamlessly automate the entire order lifecycle from an external eCommerce platform, through Sage Pay (Opayo) for payment, directly into SAP S/4HANA for order fulfillment and financial posting. This ensures real-time inventory updates, accurate sales order creation, and instant payment reconciliation.

Integration Steps:

  1. 0 Customer places order on eCommerce site, selecting Opayo for payment.
  2. 1 Opayo processes payment, returns transaction ID and status via webhook to iPaaS.
  3. 2 iPaaS maps eCommerce Order and Opayo Payment Transaction data.
  4. 3 Sales Order created in SAP S/4HANA via `/sap/opu/odata/sap/APISALESORDER_SRV` with payment reference.
  5. 4 Customer Business Partner (if new) or existing Business Partner updated in S/4HANA via `/sap/opu/odata/sap/APIBUSINESSPARTNER`.
  6. 5 Payment status updated in S/4HANA, triggering order fulfillment.

Business Outcome

Accelerated order processing, real-time inventory and financial visibility, reduced manual data entry, improved customer satisfaction.
