Creator API - Update a record value

Trying to use the API to update a record in a view with a POST :
  1. https://creator.zoho.com/api/xml/student-record/view/myob_invoice_line/?scope=creatorapi&authtoken=xxxxxx&criteria=(ID == "1612333000000917031")&newvalues=field name = Job_Code value=1234

What is wrong with this request syntax?

This request returns a zoho creator webpage.
