Setting Redirect Uri with Auth app

I am working on google app script to get data regarding past meetings .For this i have set up an Zoom Auth app . While setting app this app its asking for ‘redirect uri’ .My work is to get data to google sheet using Google App Script .So i don’t have a redirect uri to specify . So how will i go forward ? Postman is the tool i am using for testing .Currently i have given ‘’ as redirect uri in App and while testing in postman. This returns error “{“status”:false,“errorCode”:4700,“errorMessage”:“Invalid redirect url”,“result”:null}” .
