n8n If node explained: branch your workflow with a real example

说明与用途

在 n8n 中，IF 节点根据条件将工作流分为真分支和假分支。对于订单分流，金额超过 100 的订单会触发 Slack 通知，较小订单直接发送到履行 API。

问题

Determine which downstream action to take based on a numeric condition in an incoming order JSON.

结果

Orders over $100 are routed to Slack for review, while smaller orders bypass Slack and go straight to fulfillment, improving efficiency and reducing noise.

工作流

• Receive order via Webhook node
• Add IF node with condition: $json.total is greater than 100
• Connect true output to Slack node to post "Order for $120 needs review"
• Connect false output to HTTP Request node to send order to fulfillment

证据

Real example: order triage. You have a Webhook node receiving orders as JSON. Each order has a total. Orders over $100 should alert your team in Slack; smaller orders go straight to your fulfillment API.

Only one branch runs. n8n evaluates the condition and follows one path.
