Questions people ask
How do I trigger an AI agent from n8n?
Make a workflow with a trigger, such as a GitHub webhook or a schedule, followed by an HTTP Request node that posts the event data to your agent's API. Then add nodes that use the response. Example: a pull request opens, n8n sends the diff, and posts the agent's review to Slack.
Why use n8n to start agent runs?
n8n already speaks to hundreds of apps and handles webhooks, schedules and retries. Your agent only needs one clean API endpoint. That keeps event and app plumbing out of your agent code, and non-developers can change when the agent runs without touching it.
