PHP Betfair Free Access API, how to build APIRequestHeader & call any method? - php

Question

I am trying to write a simple PHP client to get some data from Betfair through the Free Access API http://bdp.betfair.com/?option=com_content&task=view&id=33&Itemid=62
I can login & get a session token, this way
$wsdl = 'https://api.betfair.com/global/v3/BFGlobalService.wsdl';
$soapClient = new SoapClient($wsdl);
try {
$ap_param = array(
'request' =>
array(
'username' => 'my_username',
'password' => 'my_password',
'productId' => '82',
'ipAddress' => '',
'locationId' => '',
'vendorSoftwareId' => '',
),
);
$response = $soapClient->__call("login", array($ap_param));
...
$response is an object containing the sessionToken param
But after several tries I am afraid I am sending the APIRequestHeader param (http://bdp.betfair.com/docs/) malformed, cause the response to any call (getAllEventTypes, for instance) is always returning the same: NO_SESSION
One try...
$ap_param = array(
'request' =>
array(
'header' => array(
'session_token' => $response->Result->header->sessionToken,
'clientStamp' => 0,
),
),
);
Another try...
$ap_param = array(
'request' =>
array(
'session_token' => $response->Result->header->sessionToken,
'clientStamp' => 0,
),
);
And lot of other tries... but
$response = $soapClient->__call("getAllEventTypes", array($ap_param));
$response is always the same
stdClass Object
(
[Result] => stdClass Object
(
[header] => stdClass Object
(
[errorCode] => NO_SESSION
[minorErrorCode] =>
[sessionToken] =>
[timestamp] => 2013-11-09T08:41:01.015Z
)
[eventTypeItems] =>
[minorErrorCode] =>
[errorCode] => API_ERROR
)
)
Someone here has faced the same problem?

Stupid typo error there...
session_token should be sessionToken
$ap_param = array(
'request' =>
array(
'header' => array(
'sessionToken' => $response->Result->header->sessionToken,
'clientStamp' => 0,
),
),
);
