Creating a customer in zoho subscription using data from a creator form

Creating a customer in zoho subscription using data from a creator form

I am intending to create a customer entry in zoho subscriptions "on success" of submitting a form. I have created the following deluge script

values = Map();
values.put("display_name",input.Coach_Name);
values.put("email",input.Coach_Email);
response = zoho.subscriptions.create("Customers","746311887",values);

However nothing happens,

Do I need to create lines for the Zoho Subscriptions API? If so where do I write that script? in the same form workflow as the above script?
