You can link to your online store from your website in a number of ways. Typically, merchants will provide one or more of the following links -
to the storefront (use your storefront URL),
to one or more specific category pages and/or product detail pages (use the URL's for the destination page(s) to which you'd like to link),
to the login page (which goes to the storefront after login), or
to the login page (which goes to the My Account page after login)
For #4 above, you can use the link below, where "AccountName" is your abbreviated Nexternal account name. Your exact Nexternal account name can be found in your Order Management System (OMS) at Settings / Edit General Information / Account Name.
For #3 above, use : https://store.nexternal.com/AccountName/login.aspx
, where "AccountName" is your abbreviated Nexternal account name.
