Google Sheets document can contain some sheets. First is default and '0'. Generally for any sheet there is address like this:
https://docs.google.com/spreadsheets/d/(spreadsheetId)/edit#gid=(sheetId)
with both spreadsheetId and sheetId.
But in API documentation there is no mention of how to use sheetId. I can only read and edit default sheet for given spreadsheetId.
If in request from code presented in exemplary link I added sheetId property I got error:
{
message: 'Invalid JSON payload received. Unknown name "sheetId": Cannot bind query parameter. Field \'sheetId\' could not be found in request message.',
domain: 'global',
reason: 'badRequest'
}
How to get access to other sheets than default in Google Sheets API and read or update fields in them?
