We're writing to let you know that Google Sheets V3 API is being shutdown on March 3, 2020.
What do I need to know?
The Sheets v4 API, launched in 2016, opened new doors to custom development with programmatic access to critical features like conditional formatting, charts, and pivot tables. Since then, Google has continually improved version 4 by supporting new Sheets features and introducing Developer Metadata.
As part of the migration to the Sheets v4 API, Google shut down the Sheets v3 API on March 3, 2020.

To ensure projects originally built on the Sheets v3 API continue working long after it is gone, we migrated our plugins (listed below) to the Sheets v4 API before March 3, 2020.

You can review the official
Google Sheets API documentation

The Sheets v4 API does not provide the “List spreadsheets for the authenticated user” operation. However, this functionality can be achieved using the
Drive API Files.list
method.
We have the following projects that previously used the Sheets v3 API:
- CF7 GSheetConnector Free & Pro
- WPForms GSheetConnector Lite & Pro
