"name": "Create an HTTP Endpoint",
"info": "The `HTTP In` and `HTTP Response` pair of nodes are the starting point for all HTTP endpoints you create.\n\nAny flow that starts with an `HTTP In` node must have a path to an `HTTP Response` node otherwise requests will eventually timeout.\n\nThe `HTTP Response` node uses the `payload` property of messages it receives as the body of the response. Other properties can be used to further customize the response - they are covered in other recipes.\n\nThe `Template` node provides a convenient way to embed a body of content into a flow. It may be desirable to maintain such static content outside of the flow.\n\nSee Node-RED cookbook [item](https://cookbook.nodered.org/http/create-an-http-endpoint) for details.",
