Quick launch summary We’re retiring the Sheets v3 API on March 3, 2020. To ensure that projects that were originally built on the v3 API continue to work, migrate your apps to the Sheets v4 API before that date. To learn more about this change, see our post on the Cloud blog. For information on transitioning your apps, check out our migration guide.
