You can transfer parameters from eTermin to a form on your own page.
The corresponding Java Script code could look like this:
window.setTimeout('window.parent.location = "http://www.IhreSeite.com?yourparameter=FIRSTNAME&yourparameter2=LASTNAME&yourparamter3=EMAIL" ',2000);
The appointment booker wants to make an appointment with you on your online booking page. In the last step, they enter their contact details and then click on "Book an appointment". After that, the appointment booker is forwarded to your external site or another form, where they would have to fill out their data again. The Java script code enables the data entered in eTermin to be automatically transferred to the form on the external site, so that the appointment booker does not have to enter it again. You can also insert placeholders in the Java Script code.
Here you can find out where you can store the Java Script code.
Note: You can also transfer various parameters to eTermin. You can find out how this works here.
