# Event Start Marks the entry point for flows used by Event to Flow and Cron to Flow agents. Use Event Start in flows that are executed by [Event to Flow](/documentation-and-resources/components-and-data/agents/types-of-agents/event-to-flow.md) and [Cron to Flow](/documentation-and-resources/components-and-data/agents/types-of-agents/cron-to-flow.md) agents. A single flow can contain more than one Event Start node, and the agent configuration selects which entry point to use. The `Condition` field is only evaluated for Event to Flow agents. ## Config * **Name** - optional display name for the node in the editor * **Condition** - optional JSONata expression used when an Event to Flow agent needs to choose among multiple Event Start nodes in the same flow. Cron to Flow agents do not use this field. ## Output Downstream nodes should read the event payload from `msg.event`. Flows used by Event to Flow and Cron to Flow agents should terminate on one or more [Event End](/documentation-and-resources/components-and-data/flows/node-reference/event/event-end.md) or [Event Error](/documentation-and-resources/components-and-data/flows/node-reference/event/event-error.md) nodes so the runtime can resolve the execution cleanly. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.contextual.io/documentation-and-resources/components-and-data/flows/node-reference/event/event-start.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
