The `http.endpoint()` function sends output data to an HTTP URL using the POST request method.

```js

    url: "http://localhost:1234/"

```

## Parameters

### url {data-type="string"}
The URL to POST to.

### mapFn {data-type="function"}
A function that builds the record used to generate the POST request.

_You should rarely need to override the default `mapFn` parameter.
To see the default `mapFn` value or for insight into possible overrides, view the
[`http.endpoint()` source code](https://github.com/influxdata/flux/blob/master/stdlib/http/http.flux)._
{{% /note %}}

`mapFn` accepts a table row (`r`) and returns a record that must include the following fields:

- `headers`
- `data`
