How can I link an affiliate link to a category in our Nexternal store?
Navigate to Affiliates / Affiliate Name / Affiliate Links / Other URL. Now replace the "EncodedURL" with any Category link. Category links can be found at Categories / Category Name / Category Link. Be sure to use the encoded version of the url. This resource may be helpful http://www.opinionatedgeek.com/DotNet/Tools/UrlEncode/Encode.aspx
