This n8n workflow automates the process of managing and refreshing API access tokens, ensuring continuous integration with external services. It is triggered either by a scheduled interval or via a webhook, making it suitable for maintaining persistent API connections without manual intervention.
The workflow begins with a Webhook or Schedule Trigger node, activating the process. Static data is initialized to store the access token and timestamp, allowing the token to persist across workflow runs. A conditional check verifies if the current token is still valid based on a time window (e.g., 1 minute expiry). If the token is outdated or missing, an HTTP request fetches a new access token from a specified API endpoint.
Once a new token is retrieved, a ‘set token in static data’ code node updates the static data store with the latest token and timestamp. If the token is still valid, the workflow proceeds without making a new API call, ensuring efficiency.
A visual Sticky Note provides guidance on static data usage, emphasizing that static data persists only in production runs triggered by webhook or schedule, not manual executions. Overall, this workflow is ideal for automating token management, reducing manual refresh tasks, and ensuring reliable API connectivity in integrated applications.
