# HTTP.Post()

Issues an HTTP POST request to the provided URL. The function returns a JSON object that contains a status value and the HTTP response.

This function only works with HTTP on port 80 and HTTPS on port 443.

## Syntax

```
HTTP.Post(destinationUrl, contentType, content, headerNames[], headerValues[])
```

The `HTTP.Post()` function has these parameters.

- `destinationUrl` (string): Required. The destination URL for the HTTP POST request.
- `contentType` (string): Required. The value to pass for the Content-Type header.
- `content` (string): Required. The content of the POST request.
- `headerNames` (array): Required. An array of header names to include in the request.
- `headerValues` (array): Required. An array of header values to include in the request.

:::note
HTTP requests created by this function automatically include the `host` and `content-length` headers. The value of `host` is always set to the domain of the URL that the request was sent to. The value of `content-length` is always set to the length of the content in the request.

  var payload = "<test>test123</test>";
  var headerNames = ["MyTestHeader1", "MyTestHeader2"];
  var headerValues = ["MyTestValue1", "MyTestValue2"];
  var result = HTTP.Post(url, contentType, payload, headerNames, headerValues);

  Write(result.StatusCode + "<br>");
