We design, build, and integrate APIs that connect your systems, unlock your data, and enable the integrations your business depends on. Clean, documented, and built to last.
Definition
API development and integration is the process of designing, building, securing and documenting the interface layer that allows software systems to share data and trigger actions — enabling your web app, mobile app, internal tools and third-party services to communicate in a controlled, versioned and observable way.
Every time a team member exports a spreadsheet to share data between systems, you are paying for an integration that does not exist.
Integration platforms solve the first mile but create technical debt at scale.
Data trapped in siloed systems forces manual processes that slow operations and introduce errors
Poor or undocumented APIs make third-party integrations fragile and expensive to maintain
Legacy systems with no API layer cannot connect to the modern tools your business needs
Inconsistent API design across teams creates a tangled stack that becomes harder to manage over time
Our Approach
We build RESTful and GraphQL APIs designed for longevity — well-structured, authenticated, rate-limited, and properly documented.
RESTful architecture with OpenAPI 3.1 specification, semantic versioning, content negotiation, rate limiting, cursor pagination and full Swagger UI developer documentation — so your API is usable from day one, not after a month of tribal-knowledge onboarding.
Schema-first design with no over or under-fetching — clients request exactly the data they need. Real-time subscriptions via WebSocket, DataLoader batching to eliminate N+1 queries, persisted queries for mobile performance and depth-limit protection against abuse.
Native integrations with Stripe, Salesforce, HubSpot, Xero, SAP, QuickBooks, Twilio, SendGrid, AWS services and any enterprise system — clean adapter layers that isolate your codebase from third-party API changes, not brittle middleware that breaks on version bumps.
Kong or AWS API Gateway configuration with OAuth 2.0 and JWT authentication, role-based rate limiting, request transformation, response caching, circuit breakers, developer portal and usage analytics — the full API management layer without the enterprise SaaS contract.
Real-time event processing with SQS, RabbitMQ or Kafka — async workflows, idempotency handling using deduplication keys, configurable retry with exponential backoff, dead-letter queues, event replay capability and full audit logging per GDPR.
OAuth 2.0, JWT, API key management, field-level encryption, threat protection against injection, SSRF and mass assignment — OWASP API Security Top 10 controls applied systematically, plus automated vulnerability scanning in the CI/CD pipeline.

iPaaS is the right call for simple, low-volume integrations. Custom APIs are right when performance, security or business logic complexity exceeds what connectors can handle.
Our Process
We audit your current systems, data flows, and integration requirements to define the right architecture.
We design the API contract — endpoints, data models, authentication, and error handling — before any code is written.
We build the API with automated tests covering every endpoint, edge case, and error state.
We deploy to your cloud infrastructure with monitoring, alerting, and full OpenAPI documentation.

REST is the right choice for most integrations — it is simpler, cacheable, and universally understood. GraphQL is ideal when clients need flexible querying across complex, interrelated data. We recommend the right approach for your specific use case.
We implement OAuth 2.0 and JWT authentication, HTTPS enforcement, rate limiting, IP allowlisting, and input validation as standard. For sensitive data, we also implement field-level encryption and audit logging.
Yes. We build adapter layers that can connect to legacy databases, file-based systems, SOAP web services, and even screen-scraped interfaces where no API exists — while abstracting the complexity behind a clean modern API.
Yes. We offer ongoing maintenance covering dependency updates, security patching, performance monitoring, and version management. We also handle adding new endpoints as your integration requirements evolve.
API development is the process of designing, building, documenting and securing the interface layer that allows software systems to communicate — so your web app, mobile app, internal tools and third-party services can share data and trigger actions in a controlled, versioned, monitored way. A well-built API is the backbone of any software product: it decouples your front end from your back end, enables third-party integrations and makes your platform extensible without rewriting core business logic.
REST is the right default for most public APIs, internal service-to-service communication and systems requiring clear HTTP caching. GraphQL is the right choice when clients have very different data requirements (mobile vs desktop vs dashboard), when you want to eliminate N+1 query problems in a BFF (Backend For Frontend), or when your data has deeply nested relationships. Cyberbeak scopes the right choice in the discovery sprint based on your client types, data shape and existing infrastructure — and builds one, not both, unless there is a genuine reason to serve both.
Every Cyberbeak API ships with an OpenAPI 3.1 specification, a live Swagger UI developer portal, a Postman collection and integration tests covering all endpoints and error states. We run contract testing (using Pact or Dredd) against the OpenAPI spec in CI so documentation stays accurate as code changes — not a PDF that goes stale the week after delivery.
Yes. Many enterprise systems — particularly in banking, healthcare, insurance and government — still expose SOAP/WSDL or XML-over-HTTP interfaces. Cyberbeak builds clean adapter layers that translate legacy protocols to modern REST or GraphQL, so your frontend and new services can work with a consistent API while the legacy system remains untouched. This is a common starting point for legacy modernisation work where a full replacement is not yet feasible.
