Ready for 3.0

by Tenkay · 406 views · created 2025-06-18 · Engineering

Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.

What this workflow does

This workflow has 4 nodes and runs when another workflow calls it. It uses only n8n's built-in nodes.

How it runs

Trigger: When another workflow calls it.

If: checks a condition and branches into true / false
encrypt (Code): runs custom JavaScript code
decrypt (Code): runs custom JavaScript code

Before you upgrade to n8n 3.0

Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.

Nodes used (3)

Execute Workflow Triggern8n-nodes-base.executeWorkflowTrigger
Ifn8n-nodes-base.if
Coden8n-nodes-base.code

From the author

This workflow performs basic XOR-based encryption and decryption using a custom password. It is intended to be triggered by another workflow and processes structured input in JSON format. Input Structure The workflow expects a single array of objects with the…
