Can my store resolves API request using custom admin url? Eg: https://admin.magento.lc/api/v2_soap?wsdl=1? Here problem is if I use api url via custom admin url it redirects to frontend.
After having a look into
/app/code/core/Mage/Api/etc/config.xml i saw, that the route is only configured for the
frontend, not for
<config> <modules ...> <global ...> <frontend> <routers> <api> <use>standard</use> <args> <module>Mage_Api</module> <frontName>api</frontName> </args> </api> </routers> ... </frontend>
So there is no admin-route for
/api which might be the cause why you get redirected. I did not test it though.
