Automated Access Token Management Workflow

This n8n workflow automates the management and renewal of an API access token, ensuring seamless authentication with a target service. The process begins with a Webhook or scheduled trigger to initiate the workflow. It checks if the current access token stored as static data is still valid based on a timestamp (1-minute expiration). If the token is valid, the workflow continues with the existing token. If expired, it makes an HTTP request to fetch a new access token, updates the static data with the new token and timestamp, and then proceeds. This process is ideal for scenarios where APIs require regular token renewal to maintain continuous operations, such as integrations with third-party services requiring OAuth tokens.

Key nodes include a Webhook or Schedule Trigger to start the workflow, static data initialization and validation, an HTTP request to fetch new tokens, and logic to determine token validity. The workflow uses static data functions to persist the token across executions, making it highly useful for automating token refresh cycles in production environments where manual renewal would be impractical.
