When a business needs a custom API — not just a plugin
See When Does a Business Need a Custom API? for the honest signals — usually when off-the-shelf integrations can't express your actual business logic, not as a default first move.
Security and documentation
Authentication boundaries, rate limiting where relevant, and documented endpoints so your own team (or a future developer) can understand and extend the API without reverse-engineering it.
What you receive
A working API for the endpoints and data model agreed in the written scope, with the authentication and permission rules agreed for it; error handling and logging for the paths in scope; written endpoint documentation; deployment to the environment you choose; and a handover, so your own team or another developer can run and extend it. Anything not in the written scope is not assumed.
What determines the scope
There is no fixed price, because the work depends on things that differ from project to project: how many endpoints and data entities the product genuinely needs, the authentication and permission model, how many outside systems it has to talk to and how good their APIs are, how much business logic lives in the backend, and the security and deployment requirements of your environment. These are written down before work starts. Where other systems are involved, the first step is an API readiness check, so integration risk is known before it is priced.
Why LATYNEX for this
A backend is only useful if someone else can run it later, so documentation and handover are scoped as part of the work rather than left as an afterthought.
Work happens inside your real existing systems, repositories and accounts, through access you grant and can withdraw.
Testing, deployment and handover are part of the way we work: checked before release, then documented so someone else can run it. This is a working practice, not a certification.
One scope and one price in writing before work starts, with what is built first and what is deliberately left out stated plainly.

Who this is for
Businesses building a web application, a mobile app, or needing a backend specifically to power integrations or AI features that a website alone doesn't need.
How it works
- 1
Agree what the backend must do
List the clients that will call it (web, mobile, AI, integrations), the data and rules it owns, and what is out of scope.
- 2
Check the systems it must connect to
Where other systems are involved, their APIs are tested first, so integration risk is known before the work is priced.
- 3
Design the data model and access rules
Entities, relationships, authentication and permission boundaries, agreed before endpoints are built.
- 4
Build and test
Endpoints, business logic, error handling and logging, checked against the agreed cases before release.
- 5
Deploy and document
Deployment to the agreed environment, with documented endpoints and configuration.
- 6
Hand over
Your team or another developer can run and extend it. Any ongoing support is agreed separately.

- How we work · Commercial terms
- One scope and one price, agreed in writing before work starts. Your accounts, code and domain stay yours; any access we use is granted by you and can be withdrawn.
There are no client case studies on this page, and none are implied. What LATYNEX has built and runs itself is on the portfolio, each system labelled by stage. Published prices are on the pricing page; anything not listed there is scoped and quoted after review.
Questions
Do we need this if we already have a website?+
Only if the website needs to do more than present content and capture leads — a marketing site alone usually doesn't need a dedicated custom backend.
Can this power a mobile app we're building elsewhere?+
Yes — backend/API work for a mobile app being built by a different team (native specialists, for example) is a common, standalone engagement.
How is security handled?+
Authentication boundaries and rate limiting are scoped per project, based on what data and actions the API actually exposes.
