REST API Development
Structured, documented APIs with secure authentication and fine-grained permissions, serving your site, app, and other systems.
The API is the backbone every interface stands on: your website, mobile app, dashboard, and any external system you integrate with. Building it correctly from the start saves rewriting everything later.
We build APIs on Django REST Framework with versioned, organised routes, JWT authentication using short-lived tokens and safe refresh rotation, and a permission system that defines precisely who reads, writes, and publishes. Every public write endpoint is rate limited against abuse.
Documentation is not optional: you get interactive OpenAPI docs where any developer can try each endpoint from the browser. We also deliver automated tests covering authentication, permissions, and input validation, so the API stays reliable through later changes. If you have an existing system with no API, we can build an API layer over it without a rewrite.
The problem we solve
Your website, app and other systems do not share data, so the same information is entered more than once, or you need to connect your system to an outside party.
Who this service is for
- Businesses whose website and app must work on the same data
- Systems that need to connect to payment, messaging or partner systems
- Front-end teams that need a documented backend to build on
What's included
Secure authentication
JWT with short tokens, safe rotation, instant revocation.
Fine-grained permissions
Per-resource control of read, write, and publish.
Interactive documentation
OpenAPI docs you can try from the browser.
Automated tests
Coverage for auth, permissions, and validation.
Deliverables
- Organised, versioned API
- Interactive OpenAPI documentation
- Automated auth and permission tests
- Developer integration guide
What we need from you
Having these ready shortens the timeline and reduces rework.
- A description of the data and operations required
- Access details and documentation for the systems to integrate
- Your security and permission requirements
How we set the timeline and cost
Timeline and cost depend on the number of resources and operations, the complexity of permissions, integrations with external systems, and performance requirements. You receive a written estimate after requirements analysis.
