Using conditions and business rules in n8n helps you control what should happen next based on the data coming into your workflow. This is what turns a simple automation into a real business process, because real workflows rarely follow only one fixed path.
IF Node (yes/no decision)
The IF node is used when you want a workflow to split into two paths: True or False. You define one or more conditions based on the incoming data, such as:
- Amount > 10,000
- Status = “urgent”
- Country = “India”
- Email contains “invoice”
Example: If a support ticket is marked “urgent,” send a Slack alert to the priority channel. If not urgent, log it to a spreadsheet.
Switch Node (multiple decision paths)
The Switch node is used when you need multiple routes, not just two. It checks a field and sends the workflow down the matching case.
- Case 1: Department = Sales → create CRM task
- Case 2: Department = HR → create a ticket
- Case 3: Department = Finance → forward for approval
Business Rules (how to design them well)
- Define rules clearly: write them like “If X happens, do Y.”
- Use clean data fields: ensure the field you check is consistent (no spelling variations).
- Add a default path: handle “no match” cases so the workflow never gets stuck.
- Keep logic readable: name nodes clearly (e.g., “IF High Priority,” “Switch by Team”).
With IF and Switch, you can automate approvals, routing, prioritisation, exception handling, and more—exactly how real work decisions are made.
