APIs That Connect and Scale Your Business
We design and build robust, well-documented APIs that connect your applications, automate data flows between systems, and provide the foundation for scalable, modern software architecture.
Problems you shouldn't have to live with
Data Silos Everywhere
Your customer data lives in your CRM, order data in your e-commerce platform, financial data in your accounting tool, and none of them talk to each other. Your team wastes hours copying data between systems.
Manual, Error-Prone Processes
Without proper integrations, your team manually exports CSVs, reformats data in spreadsheets, and re-enters it into other systems. Every manual step introduces errors and delays that compound over time.
Monolithic Architecture Limits
Your application is a single, tightly coupled codebase where changing one feature risks breaking another. Scaling specific parts of your system is impossible, and development velocity has ground to a halt.
Undocumented or Fragile APIs
Your existing APIs lack documentation, versioning, and error handling. Third-party developers and internal teams struggle to integrate, and breaking changes cause downstream failures without warning.
How we solve it
- 1
RESTful API Design & Development
We design clean, intuitive REST APIs following OpenAPI standards with consistent naming, proper HTTP methods, pagination, filtering, and comprehensive error handling that developers love to work with.
- 2
GraphQL API Development
For applications with complex data requirements, we build GraphQL APIs that let clients request exactly the data they need in a single query, reducing over-fetching and improving frontend performance.
- 3
Third-Party System Integration
We connect your application with CRMs, payment processors, shipping providers, marketing platforms, and any third-party service with an API, creating automated data flows that eliminate manual work.
- 4
API Documentation & Developer Portal
Interactive API documentation with Swagger or Redoc, code examples in multiple languages, authentication guides, and a developer portal that makes your API easy for anyone to integrate with.
- 5
Authentication & Rate Limiting
OAuth 2.0, API key management, JWT tokens, and intelligent rate limiting protect your API from abuse while ensuring legitimate users have a smooth, uninterrupted experience.
- 6
Monitoring & Performance
Request logging, error tracking, latency monitoring, and usage analytics give you complete visibility into how your API is being used and alert you to issues before they affect your users.

Questions we get asked
REST APIs use multiple endpoints with fixed data structures, which is simple and works well for most applications. GraphQL uses a single endpoint where clients specify exactly what data they want, which is ideal for complex applications with varied data requirements or mobile apps that need to minimise data transfer.
A straightforward REST API for a web or mobile application typically costs £8,000 to £20,000. A comprehensive API platform with authentication, rate limiting, documentation portal, and multiple integrations ranges from £20,000 to £50,000 depending on complexity.
A simple REST API with standard CRUD operations takes 4 to 8 weeks. A more complex API with authentication, third-party integrations, webhooks, and comprehensive documentation takes 8 to 16 weeks. We deliver incrementally so you can start integrating with early endpoints before the full API is complete.
Yes. System integration is one of our core services. We connect CRMs, ERPs, e-commerce platforms, accounting tools, marketing automation, and custom databases using their APIs. Where direct API integration isn't possible, we build middleware or use integration platforms to bridge the gap.
Yes. Every API we build comes with comprehensive interactive documentation generated from OpenAPI specifications. This includes endpoint descriptions, request and response examples, authentication guides, error code references, and code snippets in popular programming languages.
We implement API versioning from the start using URL-based versioning or header-based versioning depending on your needs. This allows us to make improvements and add features to new API versions without breaking existing integrations that depend on older versions.
Yes. We can design and build a public-facing API that lets third-party developers integrate with your platform. This includes developer documentation, API key management, rate limiting, usage tracking, and a developer portal where partners can register and manage their API access.
We implement multiple security layers including HTTPS encryption, OAuth 2.0 or API key authentication, input validation, rate limiting, request logging, and IP whitelisting. We also conduct security testing and follow OWASP API Security guidelines to protect against common attack vectors.
