API Development

APIs are the connective tissue of modern software. We design and build robust, well-documented APIs that power integrations, enable microservices communication, and open your platform to partners and third-party developers. Every API Tech With Us builds is fast, secure, versioned, and documented.

Overview

What we deliver

Our API development practice builds the backbone of modern platforms. We design RESTful and GraphQL APIs that are performant, well-documented, and secure. Whether you're building internal microservices communication, creating a public developer platform, or integrating with payment gateways and third-party services โ€” we create APIs that are a pleasure to work with. Performance, versioning, and developer experience are non-negotiable in every API we ship.

Deep-dive into our api capabilities

๐Ÿ“‹
RESTful API Design

Well-structured REST APIs following industry best practices with proper resource modeling, pagination, filtering, sorting, and standardized error responses.

๐Ÿ”—
GraphQL Implementation

Flexible GraphQL APIs with efficient resolvers, dataloader patterns, schema stitching, and real-time subscriptions for modern frontend applications.

๐Ÿ—๏ธ
Microservices Architecture

Decompose monoliths into independently deployable microservices with proper service boundaries, inter-service communication patterns, and saga orchestration.

๐Ÿ”Œ
Third-party Integrations

Connect with payment gateways (Stripe, Razorpay), CRMs (Salesforce, HubSpot), ERPs, and any third-party service through robust, resilient API integrations.

๐Ÿ“ก
Webhook & Event Systems

Real-time event-driven architectures with webhook delivery, retry logic with exponential backoff, dead letter queues, and event sourcing patterns.

Why Tech With Us

Why clients choose us for api development

Developer Experience Focus

We build APIs that developers love to use: consistent patterns, clear error messages, interactive docs, and code examples in multiple languages.

Performance Engineering

50ms average response times aren't accidental โ€” we optimize queries, implement caching layers, and load test every endpoint before production.

Backward Compatibility Guarantee

Our versioning strategies ensure existing integrations never break. We support graceful deprecation with migration guides and timeline commitments.

Production-Ready From Launch

Every API ships with rate limiting, authentication, monitoring, alerting, and comprehensive documentation โ€” not just endpoints.

Our Process

How we work

01
STEP 01
API Strategy

Defining your API architecture โ€” REST vs GraphQL, versioning strategy, authentication methods (OAuth 2.0, API keys), rate limiting policies, and documentation approach.

02
STEP 02
Schema & Contract Design

Designing API contracts with OpenAPI/GraphQL schemas, ensuring consistency, backward compatibility, and developer-friendly documentation with examples and SDKs.

03
STEP 03
Development & Testing

Building APIs with comprehensive test coverage: unit tests, integration tests, contract tests, load tests, and automated security scanning on every change.

04
STEP 04
Documentation & Launch

Interactive API documentation with Swagger/Redoc, developer quickstart guides, rate limiting dashboards, and production monitoring for every endpoint.
