Wrapper around Google Sheets API v4. You will need:

• a Google Cloud service account
• the Google Sheets API v4 enabled in your Google Cloud project
• the spreadsheet ID (provide it in the sheetId parameter)

1. Share the spreadsheet with the service account
2. Make a JSON key for the service account, minify it and set it as a secret.

• Use the secret for the serviceAccount parameter.

3. Figure out the action you want to perform.

• You will need to provide everything that comes after {spreadsheetId}/ as the action parameter. For example: values/A1:C1:append?valueInputOption=RAW

4. Figure out the request body. For example: {values: [["foo", "bar", "baz"]]}
