API Development Services

API Development Services, Built to Last

Laxaar builds and integrates APIs that other software depends on: REST and GraphQL APIs, third-party integrations, and the auth, versioning, and docs that keep them reliable. We design for the consumers, document properly, and build in the security and rate limiting production needs.

What we build

Capabilities built for production.

REST & GraphQL APIs

Third-party integrations

Connect the payment, CRM, and SaaS systems your product relies on.

Webhooks & events

Reliable event delivery with retries, idempotency, and observability.

Auth & security

OAuth, API keys, scoping, and rate limiting designed in, not bolted on.

API gateways

Gateways, throttling, and monitoring so your APIs stay fast and stable.

Docs & SDKs

OpenAPI docs and generated client SDKs that make adoption easy.

FAQ

Frequently asked questions

How much do API development services cost?

It depends on the number of endpoints and integrations. We scope it as a written, fixed-price project and send it within one business day.

REST or GraphQL, which should I use?

REST is simpler and fine for most cases; GraphQL shines when clients need flexible queries over related data. We'll recommend based on your consumers, not fashion.

Can you integrate with our existing systems?

Yes. We integrate payment processors, CRMs, ERPs, and legacy systems, including ones without modern APIs.

Do you document the APIs?

Yes. We ship OpenAPI documentation and can generate client SDKs, because an undocumented API is a support burden waiting to happen.

How do you handle versioning and breaking changes?

We version deliberately and communicate breaking changes, so consumers aren't surprised in production.

Do you secure the APIs?

Yes. Auth, scoping, rate limiting, and input validation are part of the build, not an afterthought.

ENGINEERING PHILOSOPHY

Code is useless if it's not comprehensible to those who maintain it. We write code the next person can actually understand.
