On the “New Connection” page, click “Connect new spreadsheets”. Enable Bracket permissions on the Google oauth page.
Back on the Bracket web app, select the spreadsheet name and sheet title.
Enter the name of the Google Sheet primary key. This field will uniquely identify rows in your sheet, and the values in this field should not be changed over time.
Bracket also supports syncs using dedicated Google service accounts. Ping us at eng@usebracket.com if you prefer to connect using this method.
