@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.
