Updating the script to account for due date

[linguini-00]

Hi There,

The latest API from freshbooks is able to accept due date via the due offset days field. Is there a way you can update this script to include that field or tell me how I can do that myself? I tried adding this line ":due_offset_days => '30'" but it doesn't work.

https://www.freshbooks.com/api/invoices

"invoice": {
"status": "2",
"invoice_number": "IV-1160",
"customerid": "167034",
"create_date": "2019-01-01",
"due_offset_days": "30",
"discount_value": 10,
