This workflow automates the process of monitoring and retrying failed executions in n8n on an hourly schedule. It is designed to check for errors, log into the n8n API to retrieve necessary session details, and retry any failed workflows that haven’t been retried yet. This automation is useful for maintaining workflow reliability, reducing manual intervention, and ensuring critical processes are robust against transient failures.

Step-by-step, the workflow is triggered manually or on a scheduled hourly basis. It starts with setting login credentials, then logs into the n8n API to obtain session cookies. The workflow then fetches a list of all executions with error status, filters to find those that haven’t been retried yet, and loops through these failed executions, issuing retry requests via the API. If an execution has already been retried, it skips reattempting. Additional sticky notes within the workflow guide users on setting credentials, filtering errors, and considering notifications for failed retries.

This automation is ideal for managing large or critical workflows where failures need quick attention and automatic recovery can significantly improve system uptime and reliability, especially in production environments where manual monitoring is not feasible.
