Send a message in Telegram when a row is changed in Google Sheets

What each client fills in

Telegram: Chat ID

For example -1001234567890 or @channel

Google Sheets: Spreadsheet ID

For example from the URL: docs.google.com/spreadsheets/d/<this>/edit

Google Sheets: Sheet (tab)

For example Sheet1

The accounts it needs

Each is the client’s own, stored encrypted and never copied between clients. Until one is added the client’s checklist shows it, and nothing runs.

• Google Sheets

  In your own Google Cloud project: enable the Google Sheets API, then IAM & Admin → Service accounts → Create → Keys → Add key → JSON, and paste the file here. Then share each client sheet with the service account’s email (…@….iam.gserviceaccount.com) as an Editor. The account is yours; no Google review is needed.

• Telegram

  In Telegram, message @BotFather → /newbot → copy the token. Add the bot to the client’s group, or have the client message it once.

After you install it

It lands switched off. The client’s checklist holds exactly this:

1. Connect the client’s Google Sheets, for “A row is changed”
2. Connect the client’s Telegram, for “Send a message”
3. Fill in Google Sheets: Spreadsheet ID (For example from the URL: docs.google.com/spreadsheets/d/<this>/edit)
4. Fill in Google Sheets: Sheet (tab) (For example Sheet1)
5. Fill in Telegram: Chat ID (For example -1001234567890 or @channel)
