PSP Integration & Orchestration for Global Payments

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.

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

We design flexible integration solutions tailored to your business logic — helping you connect new and existing PSPs, simplify orchestration, and scale globally with confidence.

Let's talk

Beyond the bottlenecks: a smarter payment flow

Localized PSP integrations
Quick PSP deployment
Smart routing
Analytics dashboard
Auto-failover across PSPs

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.

Costly and lengthy custom integrations

Each new PSP required months of development and QA tests, delaying market entry and eating up internal resources.

How Oxagile solved it

Used an orchestration platform with a visual editor for payment flows to accelerate PSP integration — cutting development efforts and enabling business teams to roll out new connections in weeks instead of months.

Rigid routing, higher declines

Static processor selection and basic retry attempts couldn’t adapt to real-time payment behavior, leading to avoidable drop-offs.

How Oxagile solved it

Developed a flexible, rule-based engine for routing and retries based on transaction metadata, optimizing success rates and minimizing revenue leakage.

Few performance insights

The team lacked granular insights into what was working (or failing) across payment flows.

How Oxagile solved it

Built analytics dashboards to track PSP-level metrics like approval rates, decline reasons, and latency. This enabled faster diagnosis and strategic improvements.

No backup = lost revenue

Dependency on a single PSP meant outages could stop transactions entirely.

How Oxagile solved it

Introduced multi-processor redundancy to automatically reroute transactions, ensuring business continuity even during outages.

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.”
