Looking to streamline your payment integrations?
We design flexible integration solutions tailored to your business logic — helping you connect new and existing PSPs, simplify orchestration, and scale globally with confidence.
Engineering payment flexibility
Part 1: The client
A surging company providing recurring billing and subscription management for media and entertainment platforms, helping mid-size and enterprise brands.
Part 2: The challenge
Expansion into MENA, LATAM, and Southeast Asia exposed the limits of a single-PSP setup. Payment approval rates and revenue fell, and engineering efforts became unsustainable. The team needed a scalable, orchestrated solution, without rebuilding their payment stack.
Part 3: The solution
Oxagile brought in technical strategy and integration expertise, building a flexible orchestration layer on top of Primer, to streamline connections with PSPs like Adyen, Yuno, and regional providers. This enabled faster onboarding, higher payment approval rates, and full control over payments.
The impact in numbers
Projected boost in payment approval rates in key regions
Control over workflows via orchestration setup
Processor integration, cut from months to weeks
Solution delivered: tailored integration enabling smarter payment routing
To speed up PSP onboarding and reduce failures, Oxagile designed a custom integration solution tailored to the client’s specific business needs. We worked closely with their team to understand priorities and constraints. Based on that, we proposed a flexible architecture for diverse integrations and future growth.
Custom orchestration layer
- API-first architecture designed for PSP agility
- Event-driven microservices for distributed payment logic
- Domain-driven design for clean codebase
- Seamless integration with Primer and SRM system
Infrastructure and security foundation
- Infrastructure as code with SST and version control
- Secure credential management with AWS Vault
- Scalable handling of 10K+ requests/sec under load
- Automated testing and CI/CD for safe deployments
Beyond the bottlenecks: a smarter payment flow
Approval gaps in growth regions
Global transactions in MENA, LATAM, and SEA were often declined due to misaligned data formatting and the lack of local PSP coverage.
How Oxagile solved it
Implemented an orchestration layer (Primer) that supports both local payment methods and existing gateways like Yuno and Adyen — enabling alignment with regional issuer protocols and reducing false declines. The solution runs on a cloud-native, event-driven architecture using AWS Lambda, SQS, SNS, and S3.
The backbone: modern serverless stack in action

No more 2 A.M. pager panic
We stepped in to re-architect the client’s system for reliability and observability, ensuring their platform stays up, support costs go down, and SLA targets are actually achievable.
Tailored SLA strategies
- Reliability built for business needs
- 99.99% uptime targets
- Clear maintenance interfaces for payments
Proactive monitoring & observability
- Replaced user-reported issues with real-time monitoring
- Instant alerts to the client’s team
- Issues flagged before users notice disruptions
Cost-efficient reliability
- Automated detection, reporting, and recovery
- Reduced dependence on costly Ops teams
- Enabled scaling without extra IT overhead
From the dev floor
“What made this project stand out was the combination of strict compliance requirements, complex retry logic, and the need for fast, reliable execution. We didn’t just integrate PSPs, we built a system enabling business teams to onboard new providers in weeks. The solution offered full observability into transaction flows and performance. Payments became a strategic tool, not just backend plumbing.”
