API development and system integration

We connect systems that do not talk to each other today. REST and GraphQL APIs, payment gateways, ERP and CRM, with documentation and tests.

What we do

Integrations you can rely on

Data retyped by hand between systems costs time and collects mistakes. A well-designed API removes both and opens the way to a mobile application or to partners. We build them so that an outage on the other side does not stop your company, and so that every error can be traced.

API design and development

REST or GraphQL depending on who uses the API. With versioning and documentation people can actually work with.

Payment gateways

Payment integration including notifications and the states that go wrong in practice.

ERP and CRM

Orders, customers and stock kept in sync between your systems, with no manual re-entry.

Reliable operation

Monitoring, retries of failed transfers and logs that make it clear what happened.

How we work

From idea to production in 4 steps

  1. Analysis

    A workshop, the goals, the risks and a rough estimate within 10 working days.

  2. Design

    Architecture, a UX prototype and a technical plan that holds up.

  3. Build

    Two-week sprints, a demo every Friday, access to the repository.

  4. Run

    Deployment, monitoring, an SLA and further work guided by the data.

Frequently asked questions

REST or GraphQL?

REST is a good choice for most integrations and public APIs. GraphQL pays off when different clients need different data. We recommend based on the project rather than the fashion.

Can you connect an older system with no API?

Usually, yes. We first map what the system offers and then propose the safest way to connect it.

Do we get documentation for the API?

Yes. Documentation and handover are part of the delivery, and the code is yours.

Shall we talk about your project?

Tell us what you are working on. We will get back to you and suggest the next step.
