Agile Payment Engine Implementation Service

Endava’s Agile Payment Engine Implementation Service is a 24-week consulting engagement that modernizes payment routing by deploying an Azure-native, multi-PSP orchestration platform featuring intelligent routing to optimize costs, pre-built adapters for rapid integration with major gateways and legacy systems, and a resilient, event-driven architecture on Microsoft Azure ensuring secure, scalable, and compliant payment processing.

Highlights:
• Intelligent Routing: Route transactions across multiple PSPs to optimize processing costs
• Accelerated Expansion: Leverage pre-built adapters for major gateways and legacy financial hosts
• Resilient Architecture: High-availability, event-driven deployment on Microsoft Azure

Build a Future-Proof Payment Platform on Azure
Endava's Agile Payment Engine Implementation Service is a professional engagement for businesses that need to move beyond the limitations and high fees of a single payment gateway. Our experts will design and build a modern, agile payment platform, using our proprietary Orchestration and Adapter accelerators. This service is for clients who need to own their payment infrastructure to optimize costs, improve resilience, and rapidly adapt to new markets.

Intelligent Multi-PSP Routing & Cost Optimization
At the core of our service is the implementation of a powerful Orchestration Layer deployed on Azure Kubernetes Service (AKS). We work with you to define and configure dynamic routing rules that can direct transactions to the most cost-effective Payment Service Provider (PSP) based on card type, currency, or region. This breaks vendor lock-in and significantly reduces your payment processing fees.

Accelerated Integration & Legacy Migration
We accelerate your time-to-market by leveraging our library of pre-built Payment Adapters for major gateways (like Stripe, Adyen, and Checkout.com) as well as legacy financial protocols like ISO 8583. Because enterprise modernizations are complex, our service specifically includes the custom data engineering required to build ETL pipelines. We safely migrate your legacy merchant configuration rules from your existing systems into a highly scalable Azure Cosmos DB, ensuring zero data loss during the transition.

Secure, Scalable, and Event-Driven
The platform utilizes a fully event-driven architecture to ensure transaction data is never lost. We complete the critical event bus integration as part of the core engineering phase. Additionally, the solution integrates our Secure Tokenization module and leverages Azure Key Vault to de-risk your PCI DSS compliance.

Azure Products Utilized:
• Azure Kubernetes Service (AKS): Highly available container orchestration for core payment services
• Azure Cosmos DB: Globally distributed, scalable NoSQL database for routing rules and transaction state
• Azure Event Hubs Service Bus: Asynchronous messaging backbone for transaction reliability
• Azure API Management (APIM): Secure ingress and API lifecycle management
• Azure Key Vault: FIPS-validated HSMs for cryptographic key management
• Microsoft Entra ID: Secure identity and access management
