We connect systems, e-shops, ERPs and external services over REST, GraphQL and webhooks. An integration is more than calling an endpoint – it is an agreement about what happens when the other side does not answer, sends incomplete data or changes the format without warning. Those situations decide whether the integration still runs a year later.

What we usually connect

Typically an e-shop and an ERP, a warehouse and accounting, supplier catalogues and a product database, a CRM and marketing tools, or internal systems that until now exchanged exported files. In most cases it is not a single link but a web of dependencies where one change has to flow correctly into every other system.

What we insist on

  • Retries with exponential backoff, so an outage does not mean lost data.
  • Idempotency – a repeated message never creates a second order or a duplicate record.
  • Request and response logging, so it can be proven afterwards who sent what.
  • Mapping and validation before the write, not after something has already broken.
  • Error alerts that reach you rather than an unread log file.

How it runs

We start by mapping the data flows and formats on both sides. Then we build against a test environment, walk through the edge cases and only then go live, usually on a limited set of data first. Documentation is handed over with the solution, so you are not dependent on one person.

If you already have an integration that is unreliable, we can audit the existing implementation and fix whatever keeps falling over.

Frequently asked questions

What if the other side has no documentation or API?

That happens often. We then look for another common language – a file export to an agreed location, read-only database access, or transfer via email attachment. It is not elegant, but it works reliably as long as format and frequency are agreed in advance.

How do you handle changes on the supplier's side?

We build integrations so an unexpected format change is caught by validation and reported before corrupted data is written. Critical integrations are also monitored – if data stops arriving, you hear it from an alert rather than from a customer.
