Key points

What the free version does

A “KVK number (8 digits)” box appears above the Company field. After “Look up” the company name is filled in from the register.

What Pro adds

Search by company name with a list, street, postcode and city filled in, the KVK number saved with the order, and a “company from KVK” box on the order page in the admin.

How much it costs

The base version is free. Pro costs 990 UAH, a perpetual licence. One payment, no yearly fees.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • OpenCart 4.0.2 or newer (4.1 tested).
  • PHP 8.0+, the cURL extension.
  • For production: the shop’s own KVK API subscription (KVK bills the calls).

Full module description

KVK Company Lookup lets Dutch B2B buyers type their KVK number and the checkout fills in the company name from the Kamer van Koophandel Handelsregister. The lookup runs through the shop’s own KVK API subscription, the key never reaches the browser, and KVK bills the shop for the calls. A test mode with KVK’s public test environment is built in. KVK offers no OpenCart module of its own: its developer pages list only the API.

Checked against the KVK test API. Unlike most of our new modules, this one was checked against the real KVK test API (api.kvk.nl/test, the public test key, fictitious companies).

What the free version does

A “KVK number (8 digits)” box appears above the Company field. After “Look up” the company name is filled in from the register. An unknown or too short number gives a plain message and leaves the field alone. If KVK is down or the key is wrong, the buyer simply fills in the fields as before: nothing blocks the sale. There is a daily lookup cap for the whole shop.

What Pro adds

Search by company name with a list, street, postcode and city filled in, the KVK number saved with the order, and a “company from KVK” box on the order page in the admin.

How it works, step by step

  1. Get a KVK API key (for a first try the test mode needs none).
  2. Install the module, open its settings and enable it.
  3. Check the connection with the “Test” button.
  4. Open the checkout and type a KVK number.

Under the hood

  • The KVK key stays on the server and is never put in the page.
  • Every request from the page carries a token; there are session and daily limits.
  • Languages: English, Nederlands.

How to install

  1. Extensions → Installer: upload the zip.
  2. Extensions → Modules: install and open the module.
  3. Module settings: test mode or your KVK key.
  4. Try one test order.

Install: Extensions → Installer → upload the zip, then Extensions → Modules → install and enable it. OpenCart 4.0.2 or newer is required.

@catcode_support Setup, compatibility, activation
Is this an official KVK module?

No. We made the module; KVK is the name of the register.

Do I need a KVK key?

For live data yes (a paid KVK subscription); the test mode works without one.

What if KVK does not answer?

The buyer fills in the fields, the order is not blocked.

What happens after the trial?

Pro switches off, the free part keeps working.
