Drive Google Sheets via curl + jq. The user's OAuth bearer token is in $GOOGLE_SHEETS_TOKEN; every call needs Authorization: Bearer $GOOGLE_SHEETS_TOKEN. Base URL: https://sheets.googleapis.com/v4/spreadsheets. The token carries spreadsheets.readonly (+ identity); writes need the broader spreadsheets scope.

Failures are {"error":{"code","message","status"}} — show verbatim. 401 = re-install. 403 PERMISSION_DENIED on a write = read-only scope → re-connect with read+write.

The spreadsheet id is the …/spreadsheets/d/<ID>/edit segment of the URL.

S="https://sheets.googleapis.com/v4/spreadsheets"; AUTH="Authorization: Bearer $GOOGLE_SHEETS_TOKEN"

curl -sS -H "$AUTH" "$S/SPREADSHEET_ID?fields=properties.title,sheets.properties(title,sheetId)" \
