Questions & Answers

Got questions? We've got answers.

REST or GraphQL — which should we choose?

REST is simpler and better for public APIs with predictable data needs. GraphQL excels when clients need flexible queries or you want to reduce API calls.

How do you handle API versioning?

We use URL versioning (v1, v2) for major changes and additive changes for minor updates, ensuring backward compatibility.

Can you integrate with our existing systems?

Yes — we have experience integrating with hundreds of third-party APIs including Salesforce, HubSpot, Stripe, SAP, and custom enterprise systems.

How do you ensure API security?

We implement OAuth 2.0, API keys, rate limiting, input validation, CORS policies, and encryption for all API communications.

What about API performance?

We optimise with caching (Redis), pagination, compression, connection pooling, and CDN distribution for global performance.
