How to prefill fields in WordPress forms with 123FormBuilder?

When embedding a form on a WordPress page or post, the code retrieved from the Publish → Platforms → WordPress section within our form builder normally looks like this:

[ 123-contact-form i507842 ]

In order to prefill form fields you need to change this code in the following way (in one line):

[ 123-contact-form i507842 control3592242-1=John&control3592242-2=Doe& 91577=This is a test message. ]

control3592242-1, control3592242-2, control3591576 and control3591576 are the name attributes of form fields. You can retrieve them by inspecting the code of your form with a browser inspection tool.

John, Doe, and This is a test message. represent the prefilled values assigned to the fields above.

Name attributes and values are connected through the operator &.
