Integrations

API integrations with suppliers and external systems

We connect the systems currently held together by copy-paste: suppliers, couriers, invoicing, ERP, marketplaces.

The hard part is not connecting, it is what happens when it breaks

Every integration looks elegant in a demo. The problems start the day the supplier answers in forty seconds, sends a price with a comma instead of a dot, or returns a negative stock figure.

We build integrations starting from those situations: automatic retries, a log of every call, alerts when something stays stuck, and a screen where the operator sees exactly what failed and why.

  • Importing products, prices and stock from suppliers in any format: API, XML, CSV, FTP
  • Generating shipping labels and pulling delivery status from couriers
  • Automatic invoicing and synchronisation with the accounting software
  • Publishing and synchronising on marketplaces
  • Two-way links with ERP and CRM systems

What adding a new supplier really involves

We do not start from code, we start from their real data. We take a full export and look at which fields arrive, how often the structure changes, and where the values that break an import appear: prices written with a comma, negative stock, products without a unique code, the same brand spelled four different ways.

Only once the mapping between the supplier's fields and your structure is written down do we write the import. That avoids the classic outcome where an integration runs flawlessly for two weeks and then fills the shop with wrong prices overnight.

  • A documented field mapping, so someone outside the technical team can check it too
  • Pricing rules: markup, rounding, exceptions per category or per product
  • Products that disappear from the feed are hidden, not deleted — order history stays intact
  • A schedule that matches the supplier's rhythm rather than an arbitrary one

Frequently asked questions

What people ask us about api integrations

If your question is not here, write to us — we answer just as directly.

Ask us a question
My supplier has no API, only an XML file. Is that workable?

Yes. We work with XML files, CSV exports and FTP feeds all the time. What matters is that the structure is predictable; the rest is handled at import.

What if the supplier changes their format?

The import stops in a controlled way and you get an alert, instead of writing wrong data into the shop. Adapting to the new format is a short maintenance job.

How often can stock levels be synchronised?

From every few minutes to once a day, depending on what the supplier supports and how fast the goods move. For fast-moving products we use short intervals; for the rest, a few times a day is enough.
