Store Variables Between Workflow Runs Using n8n's Built-In Data Tables (Key-Value Store)

Purpose

This workflow implements a simple key value store based on the built-in data tables feature in n8n – no external service needed.

What this is for

This is a workflow snippet which could be used to store a “last checked” timestamp or other variables between workflow runs.

Setup

Self-deploying – no extra setup needed Just clone the template into your n8n instance and follow the instructions on the
