Creating a repository of View in Browser links to use externally



I’m looking for you to point me in the direction of API documentation or a workaround that will be useful for what I am trying to accomplish:

I want to create an externally hosted repository that will contain HTML links to the “Browser View” versions of my previously sent emails (of a certain campaign).

Furthermore, when a new email (of a certain type) is sent, I would like to automate that it be appended to my list of “View This Email in a Web Browser” links.

The purpose of this is to host a site that will allow members of my organization who are not authorized Hubspot users to simply look through the list and view each prior email in their browser.

The following would also be useful to pull from the API and include in our repository
Date of Original Send
Subject Line
