I am new to this interface and struggling to get my outbound call tests working. The parameter start_url (https://drive.google.com/file/d/0B1qoEC ... sp=sharing) in my tests is probably not set up properly, resulting in call failures, either through the queuecall web service or Google Postman. The issue might be that the script (outbound.php below) is hosted on my google drive, sharable.

Error: This XML file does not appear to have any style information associated with it. The document tree is shown below.
<queuecall status="queued" call_id="32411563">
<login>pat.laclef@lansa.com</login>
<pin>XXXXXXXX</pin>
<phone_number>1XXXXXXXXXXX</phone_number>
<start_url>

</start_url>
<max_retries>2</max_retries>
<retry_interval>600</retry_interval>
</queuecall>

HTTP post via Google Postman:

<queuecalls status="failed">Missing "login" POST variable.</queuecalls>

I just wanted to add that hosting the script on google drive does not work, meaning that the VoiceXML Validator returns an error. However, it is validated when hosted on a public site. This is most likely because google encrypts the file name in the URL. But in both cases the outbound program fails as described in the initial post. So this seems to indicate that the issue lies in the Plum DEV web service program queuecall.php What do you think?

Hi,

We have edited your post to remove sensitive information (phone numbers, pins, etc). We apologize if this causes any inconvenience.

From your url, it seems like you are sending your variables as "GET" variables instead of "POST" variables, which is why our platform is returning a "Missing POST variable" error. Please adjust your script to send your parameters using the "POST" method.

Here's an example on how to do this using PHP:

Code: Select all

<?php

$params['login'] = "user1";
$params['pin'] = "12345678";
$params['phone_number'] = "tel:+12345678900";
$params['start_url'] = "http://www.mywebserver.com/~user/myscript.php";

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_URL, "http://outbound.plumvoice.com/webservice/queuecall.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch);
echo $result;

curl_close($ch);

?>

Also, the start_url you have provided will not work with our platform because it is not sending valid VXML. Instead it is providing an HTML site that displays your VXML on a webpage. As you have described in your second post, hosting your script on a public site will work correctly.

More code examples and a guide to the outbound API can be found in our documentation.

Regards,
Plum Support
