Is there a way to configure Canonical Link Metadata?

If you are saving this data for a blog post, you could save it within the ExtendedAttributes of the blog post (and later read it from the same location). 

The canonical link can be set from a widget using the $core_v2_page.SetCanonicalUrl() method ( https://community.telligent.com/community/11/w/api-documentation/65827/core_5f00_v2_5f00_page-script-api#SetCanonicalLink )

Okay, thanks for the quick reply. Also how do I properly set an ExtendedAttribute? I was trying earlier but when I tried to retrieve the ExtendedAttributes array it said Count: 0.

API entities that expose extended attributes work similarly. Here's an example from another thread that dealt with groups:

 set Extended Attributes while creating a Group 

Note that you must pass the extended attributes in the options collection on a Create/Update call.
