$ch = curl_init('https://api.textlocal.in/bulk_json/');
curl_setopt($ch, CURLOPT_POST, true);

echo $response;

Caution: Some users opt to place their request inside a code loop, while testing we highly recommend setting the test parameter to true, as occasionally an infinite loop can occur and users can consume all their credits very quickly.
