@gregg_appcoll I generally use the matter page to add matters manually. I tried automating at least partially by populating the fields in a spreadsheet and uploading. But this path is also deficient in the sense that (i) you cannot enter priority information, and (ii) you cannot enter inventor address information, among others. If API security is a problem and you want us to use spreadshet upload to import new matters, then at least the spreadsheet should include all fields necessary to import the new matter information.

@gregg_appcoll Have you tried Internet authorization form, for example? The unambiguous fields in the form are left blank when you generate the form.
