eBay Trading API GetCategories request returns 'Application name invalid' – Ebay API

When I tried to retreive all categories through the eBay Trading API with the method getCategories, I got this error:

FailureApplication name invalid.API application “222277”
invalid.127Error222277RequestError895E895_INTL_APICATALOG_17257399_R1

The header used is:

$headers = array(
    'Content-Type:text/xml',
    'X-EBAY-API-COMPATIBILITY-LEVEL: 895',
    'X-EBAY-API-DEV-NAME: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
    'X-EBAY-API-APP-NAME: xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx',
    'X-EBAY-API-CERT-NAME: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
    'X-EBAY-API-CALL-NAME: GetCategories',
    'X-EBAY-API-SITEID: 0'
);

The XML postfields:

$body = <<<BODY
    <?xml version="1.0" encoding="utf-8"?>
<GetCategoriesRequest xmlns="urn:ebay:apis:eBLBaseComponents">
    <RequesterCredentials>
        <eBayAuthToken>auth token......</eBayAuthToken>
    </RequesterCredentials>
    <CategorySiteID>0</CategorySiteID>
    <DetailLevel>ReturnAll</DetailLevel>
</GetCategoriesRequest>
BODY;

and curl code:

$connection = curl_init();
        curl_setopt($connection, CURLOPT_URL, $endpoint);
        curl_setopt($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, $body);
        curl_setopt($connection, CURLOPT_RETURNTRANSFER, 1);
        $response = curl_exec($connection);
        curl_close($connection);

    Ebay provides an API test tool.

    It will pre-populate your credentials and let you make a test call.

    Unfortunately, eBay recently discontinued their API test tool. However, there are some 3rd party ones that may suffice.

    For your issue, I recommend using the simpler Shopping API call called GetCategoryInfo. You don’t need to POST your request or send any HTTP headers, and you can build your entire call into 1 URL/REST/GET request. This makes debugging much easier.

    Either way you go about it, I don’t think you can retrieve all of eBay’s categories with 1 request. Instead, plan to loop through the category tree at each level, collecting the child category names and IDs.
