Twilio Verify API: "Requested URL was not found" - php

Question

I am using curl to perform a request to the Twilio Verify API, following the instructions here: https://www.twilio.com/verify/api
Using these instructions, I've created two php files to perform the curl request -- one to get a verification code (get_code.php), and another to check the verification code (check_code.php). These scripts are called using an ajax post to send the parameters, and the two scripts are nearly identical, save for the URL ("/start" vs. "/check").
I believe I am specifying the correct URLs, and get_code.php works, but check_code.php throws the following error:
Requested URL was not found. Please check http://docs.authy.com/ to see the valid URLs.
get_code.php
<?php
$USER_PHONE = htmlspecialchars($_POST["phone"]);
$ch = curl_init();
$curlConfig = array(
CURLOPT_URL => "https://api.authy.com/protected/json/phones/verification/start",
CURLOPT_POST => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POSTFIELDS => array(
'country_code' => '1',
'via' => 'sms',
'phone_number' => $USER_PHONE,
),
CURLOPT_HTTPHEADER => array('X-Authy-API-Key: MY_KEY')
);
curl_setopt_array($ch, $curlConfig);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
check_code.php
<?php
$USER_PHONE = htmlspecialchars($_POST["phone"]);
$VERIFY_CODE = htmlspecialchars($_POST["code"]);
$ch = curl_init();
$curlConfig = array(
CURLOPT_URL => "https://api.authy.com/protected/json/phones/verification/check",
CURLOPT_POST => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POSTFIELDS => array(
'country_code' => '1',
'phone_number' => $USER_PHONE,
'verification_code' => $VERIFY_CODE
),
CURLOPT_HTTPHEADER => array('X-Authy-API-Key: MY_KEY')
);
curl_setopt_array($ch, $curlConfig);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
I performed a curl manually in terminal using the same URL and parameters, and it worked.
curl "https://api.authy.com/protected/json/phones/verification/check?phone_number=MY_PHONE&country_code=1&verification_code=MY_CODE" -H "X-Authy-API-Key: MY_KEY"
I don't know what I could be doing wrong?

Answer 1

OK, well I have no idea why this worked, but I got it working and maybe someone else can explain why. I built the CURL URL as a string and I removed the CURLOPT_RETURNTRANSFER and CURLOPT_POST arguments.
<?php
$USER_COUNTRY = "1";
$USER_PHONE = htmlspecialchars($_POST["phone"]);
$VERIFY_CODE = htmlspecialchars($_POST["code"]);
$URL = "https://api.authy.com/protected/json/phones/verification/check?country_code=1&phone_number=".$USER_PHONE."&verification_code=".$VERIFY_CODE;
$ch = curl_init();
$curlConfig = array(
CURLOPT_URL => $URL,
CURLOPT_HTTPHEADER => array('X-Authy-API-Key: MY_KEY')
);
curl_setopt_array($ch, $curlConfig);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
