API Design & Development

API Design & Development

Power Your Product. Enable Your Ecosystem.

APIs are the backbone of modern software. Whether you’re building a product that needs to integrate with other systems, enabling third-party developers, or simply creating a clean service layer for your app—Booliant helps you design and build APIs that are scalable, secure, and easy to use.

What We Offer:

   •   API Design & Architecture

REST or GraphQL? Versioning? Authentication? We help you design APIs with the right structure and standards for your product.

   •   Custom API Development

We build high-performance, secure APIs tailored to your product and business needs—backed by clean, maintainable code.

   •   Developer Experience (DX)

A great API is only as good as its documentation. We provide clear, developer-friendly docs, examples, and onboarding flows.

   •   API Security & Best Practices

Ensure your APIs follow modern security standards—OAuth, rate limiting, IP whitelisting, and more.

   •   Third-Party Integration APIs

Need your product to connect with Stripe, Salesforce, Twilio, or others? We build robust connectors and middleware layers.

Example Use Cases:

   •   SaaS Partner API

A B2B SaaS company launching an external API for their partners to pull user activity, automate workflows, and integrate into CRMs.

   •   API-First Product

A startup building a marketplace with a mobile frontend and admin dashboard powered entirely by a clean, reusable backend API.

   •   Legacy to Modern API Migration

An enterprise migrating from outdated SOAP APIs to lightweight, secure REST endpoints with proper versioning and documentation.

   •   Internal Microservices API Gateway

A growing team adopting microservices that need a unified API gateway with authentication, monitoring, and logging.

   •   Client-Facing Data Feed

A data platform providing clients with custom analytics and reports via secure tokenized API endpoints.

Who This Is For:

   •   SaaS companies planning to launch a public or partner API

   •   Startups building API-first products

   •   Teams looking to refactor and modernize legacy APIs

   •   Businesses integrating multiple systems into a unified platform

Technologies We Use:

Node.js, Express, NestJS, Django REST Framework, FastAPI, GraphQL, Postman, Swagger/OpenAPI, and more.
