I am looking for documentation on Google script functions related to the new features introduced in the Google forms update for June 2016:

Add explanations to answers

See a summary of your responses

Choose what people can see after they submit

Send results via email

Go here for more information about features: https://support.google.com/docs/answer/7032287

None of the reference documents have been updated at the Google Developers site since the Google forms changes were implemented: https://developers.google.com/apps-script/reference/forms/

Answer 1

As of today, Apps Script doesn't yet support the new features recently launched in the UI. When they include new functionalities, they usually publish them in the Release Notes and Apps Developer Blog, you can follow them to keep yourself updated.

Answer 2

On April 27, 2017, Google added many new Google Script methods for handling Forms. The announcement is on the G Suite Developers Blog: Create Quizzes in Google Forms with Apps Scripts. Most of the methods I was originally looking for (Make this a quiz, Assign points to questions, Add explanations to answers, See a summary of your responses, and Choose what people can see after they submit) are included in the update. The documentation is at Google's Developers site. The Developers Blog has a detailed explanation (with sample code) of how to create a quiz using Apps Script.
