I needed to retrieve listings weighing between 12 and 16 ounces, so I created this simple script to show them in the console. Might help someone doing something similar.
function run(){
for (const listing of selectedListings) {
var pounds = listing.shippingOptions.packageWeightMajor;
var ounces = listing.shippingOptions.packageWeightMinor;
var weightInOunces = (pounds * 16) + ounces;
if ((weightInOunces >= 12) && (weightInOunces <= 16)) {
consoleLog(listing.title + " is " + weightInOunces + " oz");
}
}
consoleLog("done");
}
