How to call SOAP API using VXML?

Hi Plum
I have a requirement where I need to call a SOAP API and fetch few response fields.
Going through other Posts I see that Plum recommends to use <data> tag.
But how do we send request parameters & set request header for SOAP API call.
Is there any example implementation that I can refer to?

Hi Vikas,
Headers are supported but there is no SOAP method in vxml.

Do you mean that I cannot call SOAP API using <data> tag?
If not what are my options? Let me know. Thanks.

Hi Vikas,
That is correct. It is not possible to use a SOAP API using the <data> tag.
We recommend that you use some web scripting language to connect to your SOAP API and generate a valid VXML response based on the result. Here is an simple example in PHP:
start.vxml:
Code: Select all
<?xml version="1.0"?>
<vxml version="2.0">
<var name="account_number"/>
<form>
<field name="account" type="digits">
<prompt>
Please enter your account number.
</prompt>
<filled>
<assign name="account_number" expr="account"/>
<submit next="webservice.php" method="post" namelist="account_number" />
</filled>
</field>
</form>
</vxml>
Code: Select all
<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
// get the variables posted to this script
$account_number = $_POST['account_number'];
// connect to SOAP webservice
$soap_url = "http://someurl.to/your/wsdl";
$client = new SoapClient($soap_url);
$params = array(
'AccountNum' => $account_number
);
$response = $client->validate($params); //TRUE or FALSE
?>
<vxml version="2.0">
<form>
<block>
<prompt>
<? if ($response): ?>
Your account is valid.
<? else: ?>
Your accound is invalid.
<? endif; ?>
</prompt>
<exit/>
</block>
</form>
</vxml>
