Creating Tickets Using Custom Fields in Freshdesk API

I am currently working with the Freshdesk API and I am relatively new to it. I have a question regarding custom ticketing forms. Specifically, I would like to know if, after creating a custom ticketing form, I can refer to that form and create a ticket with the custom fields specified in the form.

I have been trying to access the following link for more information, but it seems to be not loading:

Could anyone kindly assist me or provide guidance on how I can proceed with creating tickets using custom fields via the API?
