Who is this workflow for? Manage and preserve essential data across your n8n workflow executions using the workflowStaticData() function. This workflow template demonstrates how to set variables that remain consistent throughout your workflows, ensuring reliable and efficient automation processes..

What does this workflow do?

  • HTTP Request Node (Optional): Configure this node to fetch an access token from your API. This step is optional if you already have a mechanism to obtain the token.
  • Set Static Data: Utilize the workflowStaticData() function to store the fetched access token and its expiry time. This ensures the data persists across workflow runs.
  • Activate Workflow: Activate the workflow to enable it to respond to triggers such as webhooks or scheduled events.
  • Trigger Workflow: Test the workflow by sending a request to the webhook production URL or waiting for the scheduled trigger.
  • Respond to Webhook: Upon triggering, the workflow processes the request using the stored static data.
  • Verify Static Data: After execution, review the workflow’s single executions to confirm that the static data has been correctly populated and persists as expected.

🤖 Why Use This Automation Workflow?

  • Persistent Data Management: Store critical information, such as access tokens, that need to survive across multiple workflow runs.
  • Efficiency Enhancement: Reduce redundant API calls by caching data, thereby optimizing workflow performance.
  • State Tracking: Maintain counters or state information to control and monitor workflow behavior over time.

👨‍💻 Who is This Workflow For?

This workflow is designed for developers and automation specialists utilizing n8n who require a method to maintain persistent data across workflow executions. It is particularly beneficial for those managing authentication tokens, configuration settings, or any stateful information within their automated processes.

🎯 Use Cases

  1. Access Token Management: Automatically store and update API access tokens that expire, ensuring uninterrupted workflow operations.
  2. Configuration Storage: Keep configuration settings consistent across executions without hardcoding values in each workflow run.
  3. Stateful Tracking: Maintain counters or status flags to monitor the progress or state of long-running workflows.

TL;DR

This workflow effectively demonstrates how to implement the workflowStaticData() function in n8n to maintain persistent variables across workflow executions. By leveraging static data, you can manage essential information like access tokens and configuration settings efficiently, enhancing the reliability and performance of your automated processes.
