System Integration & APIs
Seamlessly connect your existing systems, automate workflows, and create unified digital ecosystems.
Disconnected systems cost businesses time, money, and accuracy. At Porter Phillips, we specialise in system integration and API development that brings your technology landscape together into a cohesive, efficient ecosystem. From our base in Selby, North Yorkshire, we help businesses across the region eliminate manual data entry, automate repetitive workflows, and ensure information flows seamlessly between platforms. Whether you're connecting modern cloud services or bridging legacy systems, we have the expertise to make it work.
Custom API Development
We design and build robust APIs that serve as the backbone of your digital infrastructure. Our RESTful and GraphQL APIs are built with .NET Core, following industry best practices for security, versioning, and documentation. We create APIs that are easy to consume, well-documented with Swagger/OpenAPI specifications, and designed for reliability at scale. Whether you need internal APIs to connect your own systems or public-facing APIs for partners and customers, we deliver solutions that are secure, performant, and maintainable.
Legacy System Modernisation
Many businesses rely on older systems that still work but don't communicate well with modern tools. We specialise in legacy system modernisation — migrating .NET Framework applications to .NET Core, wrapping legacy databases with modern API layers, and gradually replacing outdated components without disrupting your operations. Our approach is pragmatic: we modernise what needs modernising and preserve what still works, minimising risk and cost while unlocking the benefits of modern architecture.
Workflow Automation
Manual processes that involve copying data between systems, sending notification emails, or generating reports are prime candidates for automation. We build automated workflows using Azure Logic Apps, Azure Functions, and custom .NET services that handle these tasks reliably and consistently. From invoice processing to employee onboarding, order fulfilment to compliance reporting — we identify the repetitive tasks that consume your team's time and automate them, freeing your people to focus on higher-value work.
Third-Party Integrations
We have extensive experience connecting with third-party services and platforms. Payment providers (Stripe, PayPal), CRM systems (Salesforce, HubSpot, Dynamics 365), accounting software (Xero, QuickBooks), communication tools (Teams, Slack, SendGrid), and countless other platforms — we understand their APIs and know how to build reliable, resilient integrations. We handle authentication, rate limiting, error recovery, and data mapping to ensure your integrations work smoothly in production.
Event-Driven Architecture
For complex integration scenarios, we implement event-driven architectures using Azure Service Bus, message queues, and pub/sub patterns. This approach decouples your systems, improves resilience, and enables real-time data flow across your organisation. Events like "order placed", "invoice approved", or "employee started" can trigger automated workflows across multiple systems simultaneously. Event-driven architecture is particularly valuable for businesses with many interconnected systems that need to stay synchronised.
