Magento extension Soap API V2: Customer Authentication

[Sabrina15]

Hello everyone,

I'm new to magento, and here I must call  SoapV2 API from a mobile application to authenticate a customer then get basket...

My problem is that the SoapV2 API has no WS allows a customer to authenticate (by login+pwd). So I need to extend the API and develop a method for authentication, but I do not know how to do that.

If anyone can help me that would be great. 

Best regards,

Sabrina

Hi,

yes, and I get to retrieve the basket, the categories ...

My problem is that I need a serviceweb to authenticate a costomer of the web site by checking if the login+pwd exists in the database and I do not know how to develop it.
