Bump on this.
In a multi-step form of 3 different pages, each with their own form, the last form is supposed to submit but the short codes for the JSON template only show you the fields in Step 3’s form.
This results in the form blowing chunks when it tries to post to the API because the field is missing and it tries to submit the short code in brackets.
Any ideas how to handle the API integration on multi-step forms? This part is under-documented.
Thanks in advance!
