Batch Update Form
Applies a batch of update operations to a Google Form in a single atomic transaction. Use when you need to modify form content after creation, including: - Adding, updating, or deleting questions and other items - Modifying form metadata (title, description) - Updating form settings (quiz mode, email collection) - Reorganizing item order within the form All updates in the batch are applied together atomically. If any update fails, the entire batch is rolled back. Use writeControl for optimistic concurrency to ensure updates are applied to the expected form version. Note: The form must have the appropriate sharing settings for the authenticated user to modify it.
