# What are the Start and End Nodes?

Each flow contains a Start Node and an End Node by default.<br>

### The Start Node

* &#x20; is designed to initiate your workflow.
* &#x20; store all your input data for easy management.
* &#x20; receives all user queries by default when using the flow through an API.
* &#x20; routes these queries to the corresponding nodes based on the workflow scenario.

### The End Node

* &#x20;  captures the results after the workflow has been executed.
* &#x20;  returns the final output of your workflow.

With the Start and End Nodes in place, you can easily get code snippets for API integration.
