ZOHO Campaign List Key & Authentication

ZOHO Campaign List Key & Authentication

Hi there,

I’m working on a site at the moment which integrates ZOHO subscription using the following Woocommerce plugin: http://codecanyon.net/item/woocommerce-zoho-subscribe/8118131

The plugin requires that we have both an 'Authentication Token' and a 'List Key’. I’ve found this article on how to locate these:  https://www.zoho.com/campaigns/help/api/authentication-token.html

However it’s not clear where in the backend we can find the ‘Settings module’  and where we can find anything to do with list keys.

Any help would be greatly appreciated.

Many thanks
