Question 1

Do you build REST APIs, GraphQL APIs, or both?

Accepted Answer

Both, and we'll recommend the right one for your use case. REST APIs are simpler, widely supported, and ideal for most integrations. GraphQL is better when you have complex data relationships and clients with varying data needs, like mobile apps alongside web apps.

Question 2

How do you handle API security?

Accepted Answer

Authentication via OAuth 2.0, JWT, or API keys with rate limiting and IP allowlisting. All traffic over TLS. Input validation, parameterised queries, and regular dependency audits. For sensitive data, we implement field-level encryption and audit logging.

Question 3

Can you integrate our software with third-party platforms?

Accepted Answer

Yes. CRMs, ERPs, payment providers, communication tools, accounting software — if it has an API, we can integrate it. We also build middleware layers that translate between incompatible systems.

Question 4

Do you provide API documentation?

Accepted Answer

Always. We deliver OpenAPI/Swagger specs, interactive documentation, and code examples in the languages your consumers use. Good documentation is part of the deliverable, not an afterthought.

Question 5

How do you version APIs to avoid breaking changes?

Accepted Answer

We design APIs with versioning from day one (e.g., /v1/, /v2/) and follow semantic versioning conventions. Breaking changes only ever happen in new major versions, with a migration period where both versions run in parallel.
