n8n lets teams build visual workflows that connect services, applications, and databases. A workflow might receive a website form, validate it, store it, notify the team, and create a project task. The goal is not to remove programming completely, but to make repeated integrations understandable and maintainable.
Define the trigger and expected result, then split the process into small steps for receiving, validating, transforming, calling services, and handling errors. Use webhooks for real-time triggers and protect them from untrusted requests. For self-hosted n8n, use HTTPS, strong authentication, secret credentials, least privilege, backups, and execution monitoring. Test with synthetic data, add timeouts and limited retries, and alert the team when a workflow fails.
