Google Apps Script - Using Google's file picker on a standalone script

I'm creating a application that requires the user to select a folder from their Drive. I'm struggling to set up the Picker API. Following this documentation I set up my project using their 'Hello World' script but after changing the 'devlopedKey' and 'clientID', I test the code to receive the error: Error 401, invalid_client, no registered origin. After searching around I found suggestions to set the Authorised JavaScript origin within the client credential to http://localhost:8888. After doing this I receive a different error: Error 400, origin_mismatch Sorry if this is a simple mistake of mine, any help would be appreciated.

You have to setOrigin specifically for google apps script.

var picker = new google.picker.PickerBuilder() // Instruct Picker to display only spreadsheets in Drive. For other // views, see https://developers.google.com/picker/docs/#otherviews .addView(google.picker.ViewId.SPREADSHEETS) // Hide the navigation panel so that Picker fills more of the dialog. .enableFeature(google.picker.Feature.NAV_HIDDEN) // Hide the title bar since an Apps Script dialog already has a title. .hideTitleBar() .setOAuthToken(token) .setDeveloperKey(DEVELOPER_KEY) .setCallback(pickerCallback) //THIS IS THE IMPORTANT LINE FOR YOU .setOrigin(google.script.host.origin) // Instruct Picker to fill the dialog, minus 2 pixels for the border. .setSize(DIALOG_DIMENSIONS.width - 2, DIALOG_DIMENSIONS.height - 2) .build(); picker.setVisible(true);
