Mobile app not receiving data from the server, frontend cannot pull products, and there is no API documentation? RESTful API with Swagger contracts solves this: clear endpoints, versioning, JWT authorization, and pagination. Clients connect without questions.

What We Offer

RESTful API development is the creation of software interfaces based on REST principles. Clear endpoints, standard HTTP methods, versioning, and Swagger documentation. REST remains the most popular and predictable way to integrate systems.

  • Resource-oriented architecture — each endpoint is a resource, GET/POST/PUT/DELETE methods work predictably. REST API for Laravel and Node.js

  • Swagger / OpenAPI — full documentation with the ability to call any method directly from the browser. Clients connect without questions

  • Versioning and pagination — v1, v2, v3 via URL or headers. Cursor and offset-based pagination for any data volumes

  • Authentication — JWT, OAuth2, API keys. Rate limiting, CORS, protection against common attacks

RESTful Development Principles

REST is not just URLs with JSON. We follow RESTful architecture principles so the API is predictable, scalable, and convenient for clients.

Resource Architecture

Each entity is a resource with its own URL (/users, /orders, /products). Standard HTTP methods: GET for reading, POST for creating, PUT/PATCH for updating, DELETE for deleting.

OpenAPI / Swagger

Specification in YAML or JSON format. Swagger UI with interactive documentation. Client generation for iOS, Android, Web — with one click.

Security

JWT for stateless authentication, OAuth2 for integration with external systems. API keys for partners. Rate limiting on every endpoint.

REST is the de facto standard for web integrations. Predictable, simple, documented. We write REST APIs so that frontend and mobile teams work in parallel and independently.

Full REST API Development Cycle

REST API is a contract between systems. We design it to work predictably under any load and versions.

  • Endpoint Design — API-first approach. Specification in OpenAPI first, then code. Clients start integration before the server is ready.

  • Versioning and compatibility — v1, v2 via URL or Accept header. Backward compatibility of old versions — clients don't break on updates.

  • API for mobile applications — RESTful API for iOS and Android clients, JWT authentication, push notifications, and data synchronization.

  • Pagination and filtering — cursor for real-time data, offset-based for historical. Sorting by any field, filtering by any attributes.

  • Monitoring and SLA — Prometheus metrics, request logging, alerts when response time is exceeded. Transparent availability monitoring.

  • API for web services — REST API integration with Laravel, Yii2, React, and Vue.js frontend. Swagger documentation and SDK for quick integration.


API-first — development starts with the contract

Specification first, then code. Frontend and mobile teams get ready documentation and a mock server. Integration starts in parallel with backend development — release is 30% faster.

Why Choose REST API from Us

Order REST API — get a reliable, documented, and secure interface for any integrations.

Swagger Contract Before Code

We describe endpoints in OpenAPI before development starts. Frontend and mobile teams work from ready documentation in parallel.

Load Testing

Every endpoint is tested under load: k6, wrk, simulation of peak scenarios. REST API handles 10,000+ RPS without degradation.

Versioning and Migrations

URI- or header-based versioning. Backward compatibility: old clients don't break when new endpoints are added.

REST request example:
// GET /api/v1/users?page=1&per_page=20
curl https://api.example.com/v1/users \
  -H "Authorization: Bearer <token>" \
  -H "Accept: application/json"
// Response: 200 OK with pagination, filtering and sorting

REST is the standard. We design APIs so that even a new developer understands the architecture in 5 minutes. Uniformity of endpoints, predictable errors, clear statuses. RESTful means predictable.
