Mapquest API key not recognized - mapquest

Question

I signed up for the Mapquest API service, and I am now testing my application, using PHP.
Under Manage Keys, I created a new key, and Mapquest gave me:
Consumer Key
Consumer Secret
I clicked on Approve All Keys
I looked up the documentation for Geocoding API Post Batch, and it says that I should include the key as one of the params.
I assumed it's the Consumer Key, so I included mine. However, when I make the call, I get the following response:
The AppKey submitted with this request is invalid.
My code:
$results = mapquest_v1_geocoding_batch_get_location(array('123 Main St, Anytown, WA', '123 Main St, Anytown, WA 98052'));
pretty_print($results);
function mapquest_v1_geocoding_batch_get_location($locations)
{
//&location=Denver, CO&location=1555 Blake St, Denver, CO 80202&location=Boulder&key=KEY
$postfields = array (
'inFormat' => 'kvp',
'outFormat' => 'json',
'thumbMaps' => FALSE,
'maxResults' => 1
);
$postfields_string = http_build_query($postfields);
foreach ($locations as $location) {
$postfields_string .= '&'.http_build_query(array('location' => $location));
}
$postfields_string .= '&'.http_build_query(array('key' => PARN_MAPQUEST_TW_TO_FB_KEY));
pretty_echo($postfields_string);
$url = 'https://www.mapquestapi.com/geocoding/v1/batch';
return jhm_curl_post_call($url, $postfields);
}
function jhm_curl_post_call($url, $postfields, $setopts_array = FALSE)
{
$results = array();
if (!$setopts_array) {
$setopts_array = array();
}
if (!isset($setopts_array[CURLOPT_RETURNTRANSFER])) {
$setopts_array[CURLOPT_RETURNTRANSFER] = TRUE;
}
if (!isset($setopts_array[CURLOPT_POST])) {
$setopts_array[CURLOPT_POST] = TRUE;
}
$setopts_array[CURLOPT_URL] = $url;
$setopts_array[CURLOPT_POSTFIELDS] = http_build_query($postfields);
$ch = curl_init();
curl_setopt_array ($ch , $setopts_array);
$results['json_response'] = curl_exec($ch);
$results['response'] = json_decode($results['json_response'], TRUE);
$results['info'] = curl_getinfo($ch);
$results['curl_errno'] = curl_errno($ch);
$results['curl_error'] = curl_error($ch);
curl_close($ch);
return $results;
}
This is the $postfields_string:
inFormat=kvp&outFormat=json&thumbMaps=0&maxResults=1&location=123+Main+St%2C+Anytown%2C+WA&location=123+Main+St%2C+Anytown%2C+WA+98052&key=xxxxxxxxxxxxxxxxxxxxxxxxxxxx
and the results of the call:
Array

The key needs to be in the url parameters after mapquestapi.com rather than in the post data. Then you should be good to go.
