I need to add a custom fields in all of our web-forms. I was trying to do that uinsg API. I'm able to add the standard fields in the form such as Address, State etc but when I try to add any custom field, I'm getting a 611 - System error. Am I missing something here? I'm making a call like below:
'method' : 'post',
