n8n Workflow: Gmail Webhook Automation with Code & Switch

Automate Gmail intake using a Webhook, with Code + Switch logic in n8n

This n8n workflow turns incoming webhook requests into structured Gmail-driven automation using a combination of Code and Switch logic—so you can route, format, and act on events reliably without manual steps.

What this workflow does

• Receives data via Webhook: it listens for incoming HTTP payloads and triggers the workflow when a request is received.
• Evaluates conditions with If: it checks the payload using an if node to determine whether the next action should proceed.
• Transforms/derives data in Code: the code node formats or computes the fields needed for downstream steps.
• Routes with Switch: it uses switch to branch logic based on the processed input, enabling different handling paths for different values.
• Sends actions to Gmail: using the gmail node, the workflow performs the relevant Gmail operation based on the routing outcome.

Use cases

• SaaS notifications: when an external system calls your webhook, send targeted updates through Gmail based on request type.
• Ops triage: route incoming events (e.g., “urgent” vs “normal”) and trigger different Gmail actions accordingly.
• Team request handling: standardize webhook payloads in Code and then use Switch to direct different email workflows.

Technical details

• n8n workflow nodes: if, set, code, gmail, switch, webhook
• Key components: Webhook trigger → conditional logic (if) → data processing (code + set) → branching (switch) → Gmail action

Designed for n8n users, automation engineers, and SaaS operators who want practical Gmail automation with clear routing and programmable input handling.
