Trying to use Dropbox Chooser with Google Apps Script Web App

Question

Getting the error: Origin does not match any app domain This is my setup function: function setupDropBox() { var options ={success: function(files) {dbxUpload(files);}} var button = Dropbox.createChooseButton(options); document.getElementById("dropbox_controls").appendChild(button); } Inserted this into the This is what the Google Apps Script Web App Deployment Url Looks like: https://script.google.com/a/mydomainname.com/macros/s/IdStringHere/exec I have a G-Suite Business Account I'm thinking it should be some substring of the Deployment Url. But this is the first time I wrote an app like this and I don't know much about it.

In order to use the Dropbox Chooser or Saver you need to pre-register the domains you'll use it on. You can do that by entering them under "Chooser/Saver domains" on your app's page on the App Console:

https://www.dropbox.com/developers/apps

If you don't do so, you'll get this error message when attempting to use the Chooser or Saver.

Note however that registering a domain allows any page on that domain to use your app key for the Chooser/Saver. In this case, you're using what appears to be a shared domain of "script.google.com", so if you register that, any page on "script.google.com" would be able to use your app key for the Chooser/Saver.
