Looking to see if it is possible to have an RSS feed of our blog posts on a Marketo Landing Page. Not finding much on the community on this other than for emails dated back in 2013. Any updates?
A Marketo LP can bring in any external data you want (just like any web page!).
No, it can't bring in external data via the Marketo server (server-to-server communication). But it can certainly bring in data from the browser side, by fetching it from an external service.
But that external service needs to accept cross-origin requests (CORS). An RSS feed, like most services designed for non-browser contexts, typically doesn't by default. But it could easily be added, your web team just needs to add the HTTP header
to the feed response. (Where https://pages.example.com is your LP domain.)
Then you can pull the data in and format it any which way you want.
