### Send SMS via Authkey API

Source: https://authkey.io/api-docs

This PHP code snippet demonstrates how to send an SMS using the Authkey API. It includes parameters for sender ID, mobile number, authentication key, message content, and template details. Ensure you replace placeholders like 'XXXX' and 'Your auth key' with actual values. The `SendSMS` function uses cURL to make the API request.

```php
<?php
$sender ='XXXX';
$mobile ='XXXXX';
$authkey='Your auth key';
$sms = urlencode("test"); 
$country_code=91;
$template_id='xxxxxxx';
$pe_id='xxxxxxx';
$url = 'https://api.authkey.io/request?authkey='.$authkey.'&mobile='.$mob.'&sender='.$sender.'&sms='.$sms.'&pe_id='.$pe_id.'&template_id='.$template_id;  // API URL

$response=SendSMS($url);  // call function that return response with code
echo $response;
function SendSMS($hostUrl){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $hostUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_POST, 0);
$result = curl_exec($ch);
return $result;
}
?>
```
