eBay GetOrders API returning 0 orders - ebay-api

Question

My eBay API call request is returning 0 orders, but I can see the orders in eBay seller site. Here is the get order request:
<?xml version="1.0" encoding="utf-8"?>
<GetOrdersRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<RequesterCredentials>
<eBayAuthToken>ABC...123</eBayAuthToken>
</RequesterCredentials>
<CreateTimeFrom>2015-03-20T00:00:00.000Z</CreateTimeFrom>
<CreateTimeTo>2015-03-30T00:00:00.000Z</CreateTimeTo>
<NumberOfDays>10</NumberOfDays>
<OrderRole>Seller</OrderRole>
<OrderStatus>All</OrderStatus>
<Pagination>
<EntriesPerPage>100</EntriesPerPage>
<PageNumber>1</PageNumber>
</Pagination>
</GetOrdersRequest>
Below is the response from eBay API:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<GetOrdersResponse xmlns="urn:ebay:apis:eBLBaseComponents">
<Timestamp>2015-04-02T04:58:21.086Z</Timestamp>

<Build>E915_CORE_APIXO_17437454_R1</Build>
<PaginationResult>

<TotalNumberOfEntries>0</TotalNumberOfEntries>
</PaginationResult>
<HasMoreOrders>false</HasMoreOrders>
<OrderArray/>
<OrdersPerPage>100</OrdersPerPage>
<PageNumber>1</PageNumber>
<ReturnedOrderCountActual>0</ReturnedOrderCountActual>
</GetOrdersResponse>

Answer 1

I don't see anything wrong but it will be useful to set WarningLevel attribute in the XML feed to High. The code below I use does works for me:
$feed = <<< EOD
<?xml version="1.0" encoding="utf-8"?>
<GetOrdersRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<RequesterCredentials>
<eBayAuthToken>$auth_token</eBayAuthToken>
</RequesterCredentials>
<OrderRole>Seller</OrderRole>
<OrderStatus>Completed</OrderStatus>
<Pagination>
<EntriesPerPage>100</EntriesPerPage>
<PageNumber>$page</PageNumber>
</Pagination>
<NumberOfDays>7</NumberOfDays>
<ErrorLanguage>en_GB</ErrorLanguage>
<Version>907</Version>
<WarningLevel>High</WarningLevel>
</GetOrdersRequest>?
EOD;
$feed = trim($feed);
$site_id = 3;//3 For UK
$call_name = 'GetOrders';
$headers = array
(
'X-EBAY-API-COMPATIBILITY-LEVEL: 823',
'X-EBAY-API-DEV-NAME: ' . $dev_id,
'X-EBAY-API-APP-NAME: ' . $app_id,
'X-EBAY-API-CERT-NAME: ' . $cert_id,
'X-EBAY-API-CALL-NAME: ' . $call_name,
'X-EBAY-API-SITEID: ' . $site_id,
);
// Send request to eBay and load response in $response
$connection = curl_init();
curl_setopt($connection, CURLOPT_URL, $api_endpoint);
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($connection, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($connection, CURLOPT_HTTPHEADER, $headers);
curl_setopt($connection, CURLOPT_POST, 1);
curl_setopt($connection, CURLOPT_POSTFIELDS, $feed);
curl_setopt($connection, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($connection);
curl_close($connection);
