How to capture multiple GET parameters with the sa

Question

I have a form deployed as a Web App through Google Apps Script and a couple fields allow you to select multiple values (ie. Like a multi-select dropdown). If I have multiple values with the same identifier in the GET request I only get the first one as a parameter in apps script.

How can I use apps script to capture multiple GET parameters with the same identifier?

Figured this out.

In your doGet or doPost function, instead of calling e.parameter you need to call e.parameters to get multiple parameters with the same name as arrays.
