To use dynamic numbers, start by adding the Kaisa script to your website. The script is available on the Einstellungen tab. 

Click on the Tracking tab.

Paste the Kaisa script to your webpage. Where should I insert my code snippet with the script?

Add all the numbers from your website to Genehmigte Nummern (allowed numbers). It will allow the script to replace them. You will find the Genehmigte Nummern in the Einstellungen tab under the Tracking section. Remember to save by clicking on Speichern.

Please note that the local area code for the number must match the customer address added in Einstellungen.

Well done, let the tracking begin!
