Connecting popular apps using n8n nodes means using n8n’s built-in integrations to move data and trigger actions across tools without writing code. Each app node usually offers common operations like create, update, search, get, delete, and sometimes triggers like new record or new message. Your job is to choose the right node, connect it to the workflow, and map the data correctly.
How it works in practice
- Step 1: Pick the app node (for example Google Sheets, Gmail, Slack, Notion, Trello, HubSpot, Airtable, PostgreSQL).
- Step 2: Add credentials so n8n can securely access the app (OAuth, API key, or token depending on the service).
- Step 3: Choose the operation (example: “Add Row,” “Send Message,” “Create Page,” “Create Contact”).
- Step 4: Map fields from previous nodes into the app node fields (example: name, email, message, status).
- Step 5: Test the node and check the output to confirm the app received the right data.
Common use cases
- Form/website leads → Google Sheets + CRM + Slack notification
- Email attachments → Google Drive upload + team alert
- New CRM deal → create task in project tool + update tracker
- Daily report → fetch metrics + format + send email/Slack summary
Key best practices
- Keep credentials organised and named clearly
- Use Set node to clean/rename fields before pushing data
- Validate required fields to avoid failed runs
- Log important outcomes (success/failure) for tracking
This skill is the foundation for building real workplace automations quickly using n8n.
