Post a message in Slack when a row is added to a database in Notion

What each client fills in

Slack: Channel

For example #leads or C0123456789

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.

• 

  In the client’s Slack: api.slack.com/apps → Create New App → OAuth & Permissions → add the chat:write scope (and channels:history, plus groups:history for a private channel, for the message trigger) → Install to Workspace → copy the Bot User OAuth Token. Invite the app to the channel.

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 added to a database”
2. Connect the client’s Slack, for “Post a message”
3. Fill in Notion: Data source ID (For example the database’s settings → Manage data sources → Copy data source ID)
4. Fill in Slack: Channel (For example #leads or C0123456789)
