APIs Other Developers Can Actually Build Against
Custom REST API development and integration work that connects your systems reliably and securely.
An API is a contract, and a badly designed one is expensive to change once other systems depend on it. Raxe Tech designs and builds REST APIs with consistent structure, proper authentication, versioning, and documentation — whether you are exposing data to partners, powering a mobile app, or connecting internal systems that were never meant to talk to each other.
Why Teams Choose Raxe Tech for API Work
Consistent, Predictable Design
Conventional REST structure, naming, and error formats, so developers consuming the API can predict how it behaves without reading every endpoint.
Authentication & Authorisation
Token-based authentication with scoped permissions, so each consumer accesses only the data it should.
Versioned From the Start
Versioning strategy in place before the first consumer integrates, so future changes do not break existing clients.
Rate Limiting & Protection
Throttling and abuse protection to keep one heavy consumer from degrading service for everyone else.
Documented for Real Use
Reference documentation with example requests and responses, so integration does not require a call with your developers.
Reliable Error Behaviour
Meaningful status codes and error messages, plus logging, so failures are diagnosable rather than mysterious.

Frequently Asked Questions
What is a REST API?
A REST API is an interface that lets separate software systems exchange data over the web using standard HTTP methods, allowing applications, mobile apps, or partner systems to read and write data programmatically.
Why would our business need a custom API?
A custom API is needed when you want to power a mobile app, let partners or customers integrate with your systems, or connect internal tools that have no existing integration between them.
How is the API kept secure?
APIs are built with token-based authentication and scoped permissions so each consumer accesses only what it should, alongside rate limiting, input validation, and transport encryption.
What happens when the API needs to change?
A versioning strategy is defined before the first integration, so new versions can introduce changes while existing clients continue working against the version they were built for.
Will the API be documented?
Yes. Reference documentation with example requests and responses is provided, so developers can integrate without needing direct support from your team for routine questions.
Can the API notify our systems when something happens?
Yes. Webhooks can be implemented so your API pushes event notifications to subscribed systems, rather than requiring them to poll for changes repeatedly.
Can you build integrations against a third-party API as well?
Yes. Integration work covers both building your own API and consuming external ones, including handling authentication, rate limits, and failure behaviour of the third-party service.
