Add a row in Google Sheets when a row is changed in Notion

What each client fills in

Google Sheets: Spreadsheet ID

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

Google Sheets: Sheet (tab)

For example Sheet1

Notion: Data source ID

For example the database’s settings → Manage data sources → Copy data source ID

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.

• 

  notion.so/profile/integrations → New integration (Internal) in the client’s workspace → Capabilities: Read content, Insert content and Update content (the row update needs the last) → copy the secret. Then open the database → ••• → Connections → add the integration.

• 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.

After you install it

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

1. Connect the client’s Notion, for “A row is changed”
2. Connect the client’s Google Sheets, for “Add a row”
3. Fill in Notion: Data source ID (For example the database’s settings → Manage data sources → Copy data source ID)
4. Fill in Google Sheets: Spreadsheet ID (For example from the URL: docs.google.com/spreadsheets/d/<this>/edit)
5. Fill in Google Sheets: Sheet (tab) (For example Sheet1)
6. Check the order of Google Sheets’s values, column by column against the client’s columns
