Good afternoon, I am currently working on a PHP page to run a series of tests using SOAP. I don't know where to begin, so here's my problem: the endpoint returns a problem with the 'parameters' aspect of my request, the returned message being "Invalid input value for message part parameters". The Code: $client = new SoapClient("http://<ipaddress>:9033/VolumeChargingService/bc7db4a81629dc4d24f7e8788a915fd8?wsdl", $options); $param = array( 'endUserIdentifier' => "tel:+11234567890", 'volume' => 100, 'billingText' => "t", 'referenceCode' => "r", 'parameters' => array( array('name' => 'source','value' => '12345'), array('name' => 'cspId', 'value' => 't'), array('name' => 'cspPassword', 'value' => 'XXXXXXXXXX'), array('name' => 'category', 'value' => '01') ) ); try { $result = $client->chargeVolume($param); } catch (SoapFault $fault) { print "SOAP Fault: (faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring})"; print_r($fault); } My Request: <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.csapi.org/schema/parlayx/bpxg/payment/volume_charging/v3_1/local" xmlns:ns2="http://www.csapi.org/schema/parlayx/payment/v3_0"> <SOAP-ENV:Body> <ns1:chargeVolume> <ns1:endUserIdentifier>tel:+11234567890</ns1:endUserIdentifier> <ns1:volume>100</ns1:volume> <ns1:billingText>t</ns1:billingText> <ns1:referenceCode>r</ns1:referenceCode> <ns1:parameters> <ns2:name>source</ns2:name> <ns2:value>12345</ns2:value> </ns1:parameters> <ns1:parameters> <ns2:name>cspId</ns2:name> <ns2:value>t</ns2:value> </ns1:parameters> <ns1:parameters> <ns2:name>cspPassword</ns2:name> <ns2:value>XXXXXXXXXX</ns2:value> </ns1:parameters> <ns1:parameters> <ns2:name>category</ns2:name> <ns2:value>1</ns2:value> </ns1:parameters> </ns1:chargeVolume> </SOAP-ENV:Body> </SOAP-ENV:Envelope> The reply I received from the company is that, if I can remove the 'ns2' from the <name> and <value> tags, it should fix my problem... But honestly, I have no idea how to do that. The request is generated with the code you see above, nothing more, nothing less.. Can anyone lend a hand here?
