Your services don't talk to each other, data has to be transferred manually, and every integration becomes a pain? API is a bridge between your systems. REST, GraphQL, WebSocket — we choose the protocol for the task, design contracts before the first line of code. No surprises during integration.
API Development is the creation of program interfaces through which your services communicate. Mobile app receives data from the server, CRM exchanges orders with the online store, the payment system confirms the transaction. We design and build APIs that work fast, securely, and predictably.
RESTful API — classic approach with clear endpoints, pagination, filtering, and sorting
GraphQL API — the client requests only the needed fields, no overfetching or underfetching
WebSocket and real-time — instant delivery of messages, notifications, and data updates
Integration with external services — payment gateways, CRM, 1C, webhooks, and synchronization
REST · GraphQL · WebSocket · gRPC · SOAP
We choose the protocol and architecture for the task. Sometimes simple REST is needed, sometimes reactive GraphQL with subscriptions, and sometimes high-performance gRPC for microservices.
Swagger/OpenAPI documentation, versioning, JWT and OAuth2 authentication. Written in PHP, Node.js, Python, and Go.
Apollo Server, GraphQL Yoga. Single endpoint, typed schema, real-time update subscriptions.
WebSocket for chats, notifications, and collaborative editing. SSE for lightweight event delivery. Connected to Node.js backend.
Payment gateways, CRM, 1C, email campaigns. We connect any third-party APIs, configure webhooks and synchronization.
A good API is when a mobile developer opens the documentation and gets the first successful response from the server in 5 minutes. We design contracts that are clear without extra calls and test every endpoint under load.
API creation is not just code. We design contracts, write documentation, test under load, and provide support after launch.
Contract Design — API-first approach. First describe endpoints in Swagger, then code. REST or GraphQL — choose the protocol for the task.
Real-time and WebSocket — chats, notifications, live updates. WebSocket, SSE, Redis Pub/Sub for thousands of concurrent connections.
API for Mobile Apps — connecting mobile client to server, push notifications, data synchronization between devices.
Documentation — Swagger UI for REST, GraphQL Playground for GraphQL. Interactive documentation with the ability to call any method.
Integration and Webhooks — connect payment gateways, CRM, 1C, messengers. Configure webhooks and automatic synchronization.
API for Web Services and Frontend — browser-backend interaction, authentication via JWT and OAuth2, session management, and query caching.
REST for classic integrations, GraphQL for flexible queries, WebSocket for real-time, gRPC for microservices. Connect any third-party services via webhooks. Choose the protocol for the specific task.
Order API development means getting a reliable interface through which your systems communicate without failures, and partners connect via documentation without questions.
First the contract and documentation in Swagger/OpenAPI, then code and tests. Frontend, mobile team, and partners work in parallel from day one.
We test the API under load before launch: k6, wrk, simulation of peak scenarios. Your API handles 10,000 requests per second.
Grafana dashboards for response time, errors, and RPS. Alerts in Telegram when SLA drops. 24/7 API support after release.
API is a promise. You promise that a certain request will receive a certain response. We make sure this promise is always fulfilled: at 10 requests per hour and at 10,000 requests per second.
