Frequently asked questions (FAQs)
- What's the difference between REST and GraphQL APIs, and which should I choose?
REST APIs are ideal for straightforward resource-based operations and work well when you have predictable data requirements. GraphQL excels when clients need flexible data fetching, reducing multiple requests to a single call. We analyze your use case, client diversity, and data complexity to recommend the best approach for your business needs.
- How do you ensure API security and protect sensitive data?
We implement multiple security layers including OAuth 2.0 / JWT authentication APIs, SSL/TLS encryption, API key management, rate limiting, and IP whitelisting. We conduct regular security audits, vulnerability assessments, and penetration testing. All our APIs are built following OWASP guidelines and industry-specific compliance standards like HIPAA, GDPR, and PCI-DSS.
- Should I choose REST, GraphQL, or gRPC for my API?
Choosing the right API architecture depends on your performance needs, data complexity, and the type of clients consuming your API. Each has unique strengths:
- REST — best for standardized resource-driven operations.
- GraphQL — ideal for dynamic queries and reducing request volume.
- gRPC — optimal for high-performance microservices and real-time communication.
After evaluating your system architecture, client needs, and data complexity, we recommend the optimal approach.
- Can you modernize our legacy applications with new APIs?
Absolutely. We specialize in extending the lifespan of legacy applications by building modern API layers that enable seamless connectivity with contemporary platforms, mobile apps, and cloud systems, without requiring a complete system rewrite.
Our approach involves wrapping legacy systems with middleware and service layers that translate old protocols into modern REST, GraphQL, or gRPC-based endpoints. This enables smoother data exchange, improved performance, and the ability to introduce new features gradually.
By modernizing through API enablement, you can reduce operational risk, minimize downtime, preserve existing investments, and move toward digital transformation through phased adoption, rather than executing expensive and risky full-system replacements.
- What if performance issues or failures occur post-launch?
We build high-resilience API infrastructures designed to detect, isolate, and resolve problems before they affect end users. Our solutions include real-time monitoring dashboards, automated failover mechanisms, intelligent retry logic, detailed logging, and alert-based escalation workflows to ensure uninterrupted uptime.
If any issue occurs, our support team is available for rapid incident response, root-cause analysis, hotfix deployment, and continuous performance optimization. We also provide SLA-backed maintenance packages, implement capacity planning, and proactively upgrade components to ensure your API remains stable, performant, and scalable as usage grows.
- How do you handle API versioning?
We follow semantic versioning and maintain backward compatibility whenever possible through a well-defined API versioning management approach. Our process includes implementing structured deprecation policies with advance notice, maintaining multiple API versions simultaneously during transition periods, and providing clear migration guides for developers and partners. This ensures existing integrations continue functioning smoothly while new features are introduced gradually, minimizing disruption to your operations and supporting long-term scalability.
