API v1 - Invalid API path to documented module/method

Question

The API documentation describes some product_attribute methods that we can work with

(http://www.magentocommerce.com/api/soap/catalog/catalogProductAttribute/catalogProductAttribute.html ).

These method names contradict what is configured in Mage/Catalog/etc/api.xml.

Documentation shows:

product_attribute.info

While the api.xml shows:

catalog_product_attribute.info

I am making a basic call using:

$proxy = new SoapClient('http://www.example.com/api/?wsdl');
$session = $proxy->login($user, $pass);
$attribute = $proxy->call($session, 'product_attribute.info', $att_name);
// $attribute = $proxy->call($session, 'catalog_product_attribute.info', $att_name);

This results in the error, Invalid API path. If I change the API module/method to the commented line above, I get the same error.

What is the correct API v1 method to use to call product attribute methods?

Answer 1

I just tested with both the cases product_attribute.info and catalog_product_attribute.info and both of them got me the same result. The details of the attribute with the attribute code $att_name.
I tested with a php script and using SoapUi. Both of them worked.
Make sure you don't have custom modules that might affect the SOAP API.
I tested this on version 1.7.0.2. If you are using an other version please specify it in the question.
