Build APIs That Let Other Systems Call In
Custom REST and GraphQL endpoints built on top of your own systems, with authentication, rate limiting and documentation in place, so internal tools and outside partners can call into your platform reliably.
50+ ERP and software projects. Zero failed projects since 2021.
Other systems can't call into your platform if nothing was built for them to call
Internal tools, mobile apps and outside partners all need a defined way to read from and write to your platform. Without purpose-built endpoints, teams either open up the database directly or rely on one-off scripts that break the moment something upstream changes. API Development is the discipline of building endpoints meant to be called: versioned, documented and secured from day one.
Endpoints scoped to what each caller actually needs
Each endpoint is designed around a specific job, whether that's letting a mobile app read order status or letting a partner create customer records, instead of exposing raw tables that break the moment your schema changes.
- REST or GraphQL, chosen by the use case.
- Versioned so existing callers keep working.
- Scoped to the data a caller actually needs.
Authentication and rate limiting from the first endpoint
Every endpoint ships with an authentication scheme appropriate to its caller and rate limits that keep usage within agreed bounds, so a single misbehaving caller can't take the platform down for everyone else.
- API keys, OAuth2 or JWT, matched to the caller.
- Rate limits enforced at the endpoint level.
- Usage visible before it becomes a problem.
Every endpoint tracked from build to release
Illustrative example. Your actual endpoint list depends on the systems you're exposing.
From a mapped use case to a documented, secured endpoint
Everything you need to ship endpoints other systems can rely on
REST and GraphQL endpoints
Endpoints designed around the use case, not a generic wrapper around your database.
Authentication
API keys, OAuth2 or JWT, matched to who is calling in.
Rate limiting
Limits enforced per endpoint so usage stays within agreed bounds.
Versioning
New versions ship without breaking callers already integrated.
Written documentation
Request and response formats, error codes and auth, documented for every endpoint.
Monitoring and handover
Usage monitored after launch, with access and docs handed to your team.

Start Building Your API
An endpoint that's undocumented or unsecured is a liability the moment someone outside your team starts calling it. Book a free consultation and tell us which systems need to be reachable.

How We Build Your APIs
From a mapped use case to a documented, secured endpoint. Here is the process behind every API we build.
Design, build and document, in that order
The contract is defined before any code is written
We map who needs to call in and what they need to read or write, then define endpoints, request and response shapes and error codes before a single line of code is written.
- Use cases mapped to specific endpoints.
- Request and response shapes agreed upfront.
- Error codes defined, not left to guesswork.
Endpoints built with security in from the start
Authentication and rate limiting are built alongside the endpoint logic itself, not added afterward, so nothing ships open by default.
- Authentication scoped to the caller.
- Rate limits enforced at the endpoint level.
- Built against your actual data model.
Nothing ships without documentation and a version
Every endpoint is tested against real call patterns, documented in full and released behind a version, with usage monitored once it's live.
- Documentation covers requests, responses and errors.
- Endpoints ship behind a version number.
- Usage monitored after go-live.
