A modular kit of microservices built on SAP Integration Suite to validate, enrich, and orchestrate payment processing across multiple systems.
What is this Project?
Enterprise Payment Orchestration
This project implements a set of microservices that validate payment data against different external and internal systems before securely forwarding the enriched payload to SAP.
Asynchronous & Event-Driven
The solution follows an asynchronous, event-driven architecture where SAP acts both as a consumer and a producer of events through webhooks.
Integration-Centric Design
Designed as an integration kit, the solution can be reused, extended, and adapted to support new payment validation rules and systems.
Core Capabilities
Payment Validation
- Validate payment payloads against multiple external systems
- Apply business and compliance rules
- Reject or flag invalid payments early in the process
Payload Enrichment
- Enhance incoming payment data with additional attributes
- Merge responses from multiple validation services
- Produce a normalized, SAP-ready payment payload
SAP Integration
- Send validated payments to SAP systems
- Support synchronous and asynchronous communication
- Ensure contract-compliant payloads for SAP interfaces
Webhook Continuation Flow
- SAP triggers a webhook after payment processing
- Webhook invokes a downstream microservice
- Continues post-SAP processing and orchestration
Technical Solution
SAP Integration Suite
The solution is implemented using SAP Integration Suite, leveraging its integration flows, adapters, and monitoring capabilities to manage enterprise-grade message processing.
Microservices Architecture
Each validation and enrichment responsibility is encapsulated in an independent microservice, allowing isolated deployments, scalability, and easier maintenance.
Event-Driven Processing
Payment flows are handled asynchronously, enabling parallel validation against different systems and reducing overall latency.
Secure Communication
All interactions are secured using enterprise authentication and authorization mechanisms, ensuring data integrity and compliance.
End-to-End Flow
Incoming payment requests are received by the integration layer and routed to multiple validation microservices. Each service validates and enriches the payload independently.
Once validation is complete, the enriched payment payload is sent to SAP for further processing. After SAP completes its internal logic, it triggers a webhook to a downstream microservice to continue the workflow.
Why This Architecture?
Scalability
Independent microservices scale based on validation demand without impacting the entire system.
Extensibility
New payment validation systems can be added with minimal changes to existing integrations.
Enterprise Reliability
SAP Integration Suite provides monitoring, retry mechanisms, and error handling required for mission-critical payment flows.
