I found this request 10 years ago without any answers: https://help.zoho.com/portal/en/community/topic/submit-form-via-ajax-in-zoho-crm

I wonder at this time (10 years after this question), could we add whitelist domain or any solution to submit the form via AJAX? I think it's the needed request since we want customers submit entry via my website without using iframe because I want to add my custom styles & animation to this form to adapt my website's style.
