What is an API integration?

An API integration is a connection that lets two systems talk to each other automatically: a new order in your shop becomes a customer in your bookkeeping straight away, a deal in your CRM becomes an invoice. Separate tools with nothing between them are what actually cost money: you key the same details in over and over, mistakes slip in and nobody knows which system holds the right version. We build the connections that make your stack work together, from ready made workflows to fully custom work.

Who it is for

Anywhere systems sit apart from each other.

The biggest gain usually sits in the connections you still make by hand.

What we do

Three ways to
connect your stack.

Connecting systems to each other
01

Connecting systems to each other

We link your CRM, bookkeeping, web shop and other tools through their REST API or webhooks. Data flows through automatically, in both directions, so everyone works from the same source.

One source of truth
02

Workflow automation

For links between hundreds of apps we use n8n, Make or Zapier. Visual workflows that turn an action in one system into an action in another, without heavy custom code.

Custom API development
03

Custom API development

For higher volumes, strict requirements or sensitive data we build connections to order with Node.js or Next.js API routes. With error handling, retry logic and monitoring, so you see an outage before your customer does.

Robust and documented
How it works

From separate tools to one machine.

01step 1

Intake and system mapping

We map your tools, your data flows and the points where things grind, so we know exactly where the gain sits.

02step 2

Architecture and approach

We design the connection: which platform, which error handling, and how we deal with retry logic and rate limits.

03step 3

Build and test in staging

We build the integration in a safe test environment and simulate the edge cases before live data runs through it.

04step 4

Live and monitored

Once approved the connection goes live with alerts, plus clear documentation so your team can work with it on their own.
