We sometimes earn from a click. That does not change the order. How we make money
Notification infrastructure to send email, SMS, push, Slack and in-app messages from your own app through one API.
Suits developers who do not want to build notifications by email, SMS, push and in-app themselves, with a generous free plan.
On the Knock website
REST API that returns the street and town for a postcode and house number, with plug-ins for WooCommerce and Magento.
Suits web shops and developers who only want to autocomplete Dutch addresses from postcode and house number, for a fixed amount per month.
On the Postcode API website
You get Knock or Postcode API with the differences in a one-off email. We don't store your address for this.
We get a fee if you take out a subscription through us. That does not change our verdict.
