Hi, so I want to be able to automatically add the link to the root page of the blog of the company to their microstore.

Any idea how I can identify if a blog page is a root level page from within the controller files?

Check by parent_id. The value will be 0 for root level blog posts

Thanks! That helped, quick follow up question, how does the backend system (vendor panel) differentiate when you're editing a page or a blog? Is there a variable I can check for that?

Blog

page_type=B

Page

page_type=T
