Yes it is. As long as the API key is used within the same organisation.

With the WW code you can only log in to www.kvk.nl. On the Developer Portal you log in with your chosen username and password.

• Request a new API key: go to the Developer Portal, fill in all details and request an API key/connection. With one connection you can use all APIs (Zoeken, Basisprofiel, Vestigingsprofiel en Naamgeving).
• Request extra API key: login to My Developer Portal and request an extra API key.

With an extra API key, you can easily distinguish between administration, usage and billing.

An extra API key connection costs € 6 per month. When you use an API you pay € 0,019 per query (KVK Handelsregister Zoeken is free).

You can cancel an API subscription in writing. Send a letter to your Chamber of Commerce regional office or an email to: account@kvk.nl. Keep in mind that a letter will take longer to arrive and that this can result in an (extra) month transition and subscription costs.

The agreement continues until the last day of the following calendar month and ends thereafter. For example: if you cancel on November 2, the agreement will continue until December 31.

At the moment it is not possible to transfer an API subscription to another Chamber of Commerce number. You can cancel the old connection and then request a new one.
