API Development FAQ

Common questions about API development and integration services

What types of APIs do you develop?

I specialise in REST APIs using .NET 9 and C#, including web APIs, third-party integrations, and internal system APIs. I also work with GraphQL, webhooks, and legacy API modernisation projects.

How long does API development typically take?

Simple APIs can be developed in 1-2 weeks, whilst complex integrations with multiple systems may take 4-8 weeks. The timeline depends on complexity, number of endpoints, security requirements, and testing needs.

Do you provide API documentation?

Yes! All APIs come with comprehensive documentation including endpoint specifications, authentication methods, request/response examples, and integration guides. I use industry-standard tools like Swagger/OpenAPI for clear, interactive documentation.

Can you integrate with our existing systems?

Absolutely! I have extensive experience integrating with CRM systems, ERPs (including SAP), e-commerce platforms like Shopify, databases, and cloud services. I'll assess your current infrastructure and design seamless integrations.

How do you ensure API security?

Security is paramount in all API development. I implement authentication (JWT, OAuth2), authorisation controls, rate limiting, input validation, HTTPS encryption, and regular security testing to protect your data and systems.

Do you provide API maintenance and support?

Yes! I offer ongoing maintenance including monitoring, performance optimisation, security updates, and feature enhancements. This ensures your APIs remain reliable, secure, and performant as your business grows.
