What We Build

Our API Development Services

From API strategy and design to security, developer experience, and lifecycle governance.

API Strategy & Design

API-first design, OpenAPI/Spec-first, domain modeling, a REST vs GraphQL vs gRPC decision framework, and versioning strategy.

REST API Development

Resource-oriented design, HATEOAS, pagination, filtering, sorting, RFC 7807 error standards, idempotency, and caching headers.

GraphQL API Development

Schema design, federation (Apollo), query complexity limiting, persisted queries, DataLoader, and subscriptions over WebSockets.

gRPC & Async APIs

Protocol Buffers, unary and streaming RPC, gRPC-Web, gRPC-Gateway, AsyncAPI, and Kafka/EventBridge integration.

API Gateway & Management

Kong, Apigee, AWS API Gateway, Azure API Management — rate limiting, quotas, monetization, and a developer portal.

Security & Developer Experience

OAuth 2.0/OIDC, mTLS, JWT, interactive docs, SDK generation, sandbox and mock servers, contract testing, and scorecards.

API Styles

Choose the Right API Style

We help you pick the right tool for the job — with trade-offs made explicit.

REST

Public APIs, simple CRUD, caching, and broad client support.

Public & Simple

GraphQL

Complex queries, multiple clients, federation, and mobile apps.

Complex Clients

gRPC

Internal services, high throughput, streaming, and polyglot teams.

High Throughput

Async / Events

Decoupling, event-driven flows, webhooks, and event sourcing.

Event-Driven

Webhooks

Real-time notifications and integration for external systems.

Real-Time
How We Work

The API Lifecycle

Design → build → secure → manage → deprecate — a disciplined, repeatable process.

01

Discover & Model

API-first thinking, domain modeling, and a REST vs GraphQL vs gRPC decision framework.

Week 1
02

Design & Spec

OpenAPI/Spec-first contracts, versioning strategy, and RFC 7807 error standards.

Week 1–2
03

Build & Secure

Implementation with OAuth 2.0/mTLS, unit and contract testing, and WAF protection.

Week 2–5
04

Manage & Evolve

Gateway, rate limits, docs and SDKs, breaking-change detection, and deprecation lifecycle.

Ongoing
Why TPROSYS IT

Developer-First, Security Obsessed

We treat APIs as products — with developer experience, governance, and security built into every stage of the lifecycle.

Documented by Default

OpenAPI specs, interactive docs, mock servers, and SDKs so consumers integrate in hours, not weeks.

Secure Access

OAuth 2.0/OIDC, mTLS, JWT, scopes and claims, WAF and bot protection — OWASP API Top 10 covered.

Governed Lifecycle

Versioning, breaking-change detection, API scorecards, and deprecation policies enforced as code.

FAQ

Frequently Asked Questions

Quick answers about styles, security, docs, and integration.

REST suits simple CRUD, caching, and broad client support; GraphQL shines for complex queries, multiple clients, and mobile. We run a decision workshop covering your clients, traffic patterns, and team skills before recommending a style — or a hybrid.
OAuth 2.0/OIDC, mTLS, JWT, scopes and claims, rate limiting, WAF and bot protection, plus penetration testing aligned to the OWASP API Top 10 and compliance needs like PCI, HIPAA, and GDPR.
Yes. Every API ships with OpenAPI specs, interactive docs (Scalar, Redocly, Swagger UI), sandbox and mock servers, and generated SDKs for TypeScript, Python, Go, and Java.
Absolutely. We build API facades over mainframes and ERPs, apply the strangler-fig pattern, and use change data capture for real-time sync — so legacy capabilities become modern, consumable products.
We combine URI/version-header strategies, contract testing (Pact), schema linting (Spectral), breaking-change detection, and a deprecation lifecycle with clear migration windows — enforced through API scorecards.
