Why WebBrain

REST & GraphQL API Development Company in Delhi, India

Web Brain InfoTech delivers REST and GraphQL API development solutions to clients in Delhi NCR, across India, and internationally, including the United States, United Kingdom, UAE, Canada, and Australia.

APIs act as the communication layer between frontend applications, backend systems, mobile apps, and third-party services. We help businesses choose and implement the right architecture for performance, scalability, and long-term maintainability.

What Is REST & GraphQL API Development?

API development is the process of building structured interfaces that allow different software systems to communicate, exchange data, and trigger actions over HTTP.

REST APIs

Resource-based architecture using standard HTTP methods

CORE

GraphQL APIs

Flexible query language for precise data fetching

Hybrid Solutions

Combining REST & GraphQL for optimal results

Authentication

OAuth 2.0, JWT, API Keys

Versioning & Docs

Swagger, OpenAPI, Schema Introspection

Security & Scaling

Rate limiting, caching & monitoring

Well-designed APIs are essential for scalable applications serving multiple platforms from a single backend.

Key Differences Between REST and GraphQL

Choosing the right architecture impacts performance, scalability, and maintainability.

Data Fetching

REST: Fixed endpoints | GraphQL: Client-defined queries

Over/Under-fetching

REST: Common issue | GraphQL: Largely eliminated

Multiple Resources

REST: Multiple requests | GraphQL: Single request for nested data

Versioning

REST: URL versioning | GraphQL: Schema evolution

Best Use Cases

REST: Simple apps | GraphQL: Complex relational data

Got Questions?

Frequently Asked Questions

Straight answers about REST & GraphQL API Development.

No. GraphQL excels with complex relational data, while REST remains simpler and more suitable for straightforward, resource-based applications. The right choice depends on your project needs.

Yes. A GraphQL layer can be built on top of existing REST APIs, allowing gradual adoption without rebuilding the entire backend.

Over-fetching occurs when an API returns more data than needed. Under-fetching requires multiple requests. GraphQL is designed to solve both problems.

REST typically uses URL versioning (v1, v2). GraphQL evolves the schema by adding fields without strict breaking changes.

GraphQL has unique considerations like query complexity limits, but with proper implementation it can be secured to the same standard as REST.

Timelines vary by complexity — from a few weeks for simple APIs to several months for large-scale systems with complex business logic.

Yes. We offer monitoring, performance optimization, and maintenance support after deployment.
