API Development & Integration Services
CookMyTech is a custom API development company. We engineer high-throughput RESTful and GraphQL APIs, secure API gateways, asynchronous webhook pipelines, and third-party SaaS integrations designed for high concurrency, security, and developer clarity.
Brittle APIs, Undocumented Endpoints & Lost Webhooks
Poorly designed APIs cause endless developer frustration: missing documentation, inconsistent error formats, unindexed database queries that spike latency, and lack of rate limiting that leaves systems vulnerable to DDoS attacks.
When processing third-party webhooks (like Stripe payments or CRM events), synchronous handling causes dropped transactions during network hiccups, leading to revenue loss and data corruption.
Self-Documenting, Resilient API Architecture
We design APIs strictly around modern industry standards: clear HTTP semantics, strict JSON validation schemas, cursor-based pagination, Redis caching for sub-25ms response speeds, and asynchronous queue workers.
- ✔ OpenAPI 3.0 specs with live interactive Swagger testing
- ✔ Idempotent webhook receivers with dead-letter queue recovery
- ✔ Token-bucket rate limiting and DDoS protection per tenant
- ✔ High-concurrency Node.js, Fastify, and Go microservices
Who Our API Development Services Serve
SaaS Founders & Product Teams
Companies engineering public developer APIs, webhook notification networks, and partner ecosystems to turn their standalone software into an extensible platform.
Mobile & Cross-Platform Teams
Engineering teams requiring unified, high-speed GraphQL or REST backends serving iOS, Android, and web clients with zero data duplication.
Enterprise Systems Integrations
Businesses connecting legacy ERPs, payment processors, CRMs, and internal databases into secure, unified API endpoints.
Supported API Frameworks & Protocols
Our API Development Process
API Specification & Data Contract Design
We define REST resources or GraphQL schemas, payload structures, pagination models (cursor vs offset), and status code standards in an OpenAPI 3.0 blueprint.
Backend Microservice Engineering
We build high-concurrency API routers using Node.js, Express, Fastify, or Go, enforcing input schema validation and centralized error handling.
Authentication & Role-Based Access Control
We configure OAuth2, API key hashing, JWT validation, and granular role permissions ensuring secure multi-tenant isolation.
Resilient Webhooks & Caching Integration
We engineer asynchronous queue workers, Redis caching for high-read endpoints, and idempotent webhook listeners for external event feeds.
Automated Testing, Documentation & Cloud CI/CD
We write automated integration test suites (Supertest), generate interactive Swagger documentation, and deploy to AWS, GCP, or Docker with CI/CD.
Project Deliverables
Every API build is delivered fully documented with client SDKs and automated testing pipelines.
- ✔Production-ready API codebase in TypeScript (Node.js/Fastify) or Go
- ✔OpenAPI 3.0 / Swagger documentation with interactive testing console
- ✔Auto-generated TypeScript client SDK for seamless frontend integration
- ✔Secure authentication engine with API key management and JWT rotation
- ✔Asynchronous webhook receiver with idempotency guards and Redis task queues
- ✔Automated unit and integration test suite with high test coverage
- ✔Docker containerization manifests and automated CI/CD deployment pipelines
Security, Rate Limiting & Reliability
We design APIs to withstand malicious payloads and sudden traffic spikes:
- • Token-Bucket Rate Limiting: Configurable requests-per-minute limits to protect backends from brute force and abusive bots.
- • Strict Schema Sanitization: Request bodies and query parameters validated against Zod schemas before hitting business logic.
- • Idempotency Keys: Preventing duplicate charges or record mutations by tracking idempotency keys on mutation endpoints.
- • Zero Platform Lock-In: Fully containerized microservices ready to run on any cloud provider.

Frequently Asked Questions
What is the difference between REST and GraphQL APIs, and which should we choose?
REST APIs structure data across distinct HTTP endpoints (e.g. /users, /orders) and are ideal for public integrations, cached resource retrieval, and microservices. GraphQL allows client applications to query exact data shapes in a single request, eliminating over-fetching and multiple network roundtrips. We help you choose the right approach or build unified hybrid architectures based on your client requirements.
Do you provide self-documenting OpenAPI / Swagger specifications and client SDKs?
Yes, every API built by CookMyTech includes interactive Swagger UI / OpenAPI 3.0 documentation, automated Postman collections, and auto-generated TypeScript client SDKs to ensure seamless integration by internal and external developers.
How do you engineer webhook integrations to ensure zero dropped events?
We build resilient webhook receivers utilizing background queues (Redis / BullMQ / AWS SQS) with idempotency key checking to prevent duplicate transaction processing. Failed deliveries are routed to Dead Letter Queues (DLQ) with automated exponential backoff retries and alerting.
What security measures do you implement for production APIs?
We implement industry-standard API security: OAuth 2.0 and PKCE flows, short-lived JWTs with cryptographically signed keys, API key generation with per-tenant rate limiting, CORS whitelisting, IP throttling, and automated input validation via Zod schemas to block injection attacks.
What factors influence the cost and timeline of custom API development?
Cost and delivery timelines depend on endpoint quantity, database complexity, third-party SaaS integration count (e.g. payment gateways, CRMs, ERPs), real-time WebSocket requirements, and compliance standards. Standard API microservices typically ship within 3 to 6 weeks.
