API Development & Integration

Connect your systems with RESTful and GraphQL API development, secure webhook infrastructure and reliable third-party integrations.

A scenario where data produced by one system needs to be processed by another, yet the two systems are not connected — this situation gives rise to manual copying, separate data files, and workflows riddled with synchronization errors. Whether your mobile application needs to communicate with your web application, your e-commerce site needs to automatically send orders to your ERP, or you need to use third-party service data within your own system, a well-designed API layer is essential.

Our Solution Approach

In API development and integration projects, architectural decisions come first: REST or GraphQL, which data is transferred in what order, how authentication works, and what happens in error scenarios. This flow is clarified before any code is written. APIs developed with Node.js or Python are documented to OpenAPI/Swagger standards, so the integrating team can understand what is happening simply by reading the documentation.

Scope & Features

RESTful API development — Resource-based, HTTP-compliant, versioned API design and OpenAPI documentation
GraphQL API — Flexible query structure where the frontend team fetches exactly the data it needs; eliminates over-fetching and under-fetching
Webhook infrastructure — Event-driven data transmission; real-time notifications to other systems and secure payload validation
API Gateway setup — Central layer through which all API traffic passes; rate limiting, logging, and auth control in a single point
Authentication and authorization — JWT, OAuth 2.0, API key management; endpoint-level access control
Third-party integrations — Secure API connections with payment, marketplace, shipping, accounting, CRM and operations systems
Rate limiting and quota management — Excessive request protection, client-based quota tracking and 429 error handling
Integration testing and sandbox — Sandbox environment testable without touching the live API, and automated integration tests

Technical Standards

APIs developed with Node.js (Express or Fastify) or Python (FastAPI) are supported by Prisma or SQLAlchemy ORM, PostgreSQL or MSSQL database, and a Redis caching layer. All APIs are documented in OpenAPI 3.0 format. Deployment is carried out via Docker containers.

Who Is It For?

Software teams that need a reliable backend API for mobile applications, web applications, or third-party services
Organizations that want to connect multiple internal systems to one another and migrate to a centralized API layer
Businesses that use or want to improve an existing system’s API and are seeking technical consulting

Expected Outcomes

Data flow between systems becomes automatic and reliable; the need for manual transfer is eliminated
Since mobile applications, web applications, and third-party services all draw from the same data source, inconsistencies are avoided
With documented and versioned APIs, new integrations are completed much more quickly
Centralized auth and rate limiting minimizes security vulnerabilities and the risk of abuse

Frequently Asked Questions

What is the difference between a REST API and GraphQL, and how do you choose?

REST gives you a resource-based, HTTP-compliant and versioned structure. GraphQL lets the frontend team fetch exactly the data it needs, which removes over-fetching and under-fetching. The decision is made together before any code is written, while the data flow and usage scenario are being clarified.

Which external systems can be integrated?

Secure API connections are built with payment, marketplace, shipping, accounting, CRM and operations systems. When event-driven data transfer is needed, webhook infrastructure comes into play; the other system gets a real-time notification and the incoming payload is securely validated.

Can we test the integration without touching the live system?

Yes. A sandbox environment that works without touching the live API is set up, and automated integration tests are written. Connection errors show up before they ever reach production data.

How do you prevent the API from being abused?

A central API Gateway layer carries all traffic, so rate limiting, logging and authentication checks sit in a single place. Access is limited per endpoint with JWT, OAuth 2.0 or API keys, and excessive requests are handled with client-based quotas and 429 error handling.
