get_nonce method conflicts with woocommerce plugin?

http://mysite.com/api/get_nonce/?controller=user&method=generate_auth_cookie
Got this to work with following response:
{"status":"ok","controller":"user","method":"generate_auth_cookie","nonce":"1615ea4086"}

But when I activate the Woocommerce plugin, it seems to fail. The above api url will aut redirect to:
http://mysite.com/api/get_nonce/?v=6cc98ba2045f
and the error response will be:
{"status":"error","error":"Include 'controller' and 'method' vars in your request."}

Is their any workaround I can do with this issue?
