## Overview

The `sendWebhook` utility allows you to ping a URL at the time a message renders (preview or send). This is useful if you need to ping a URL with a query string unique to the contact.

```php
sendWebhook($url)
```

## Example

```php
{$webhook_response = $utils->sendWebhook("http://analytics.example.com/pingme?cID=$cID&mcID=$mcID&msID=$message.msID")}
```

Due to the high traffic volume that the `sendWebhook` utility can generate, it's recommended to only use this on a service your company owns or a service that your company has explicit permission to use.
