Properties Webportal Datafeed

Hi Everyone:

Im trying to design a solution for estate agents where they can showcase their properties as they come but at the same time I was thinking how make a channel for the datafeed so that at a given time it will be automatically be populated in their accounts in different properties management portals.

I am new in this area and haven’t got a vivid picture of the workflow and how to achieve this, can any give me a heads-up?

thanks
