So I’m building a real estate website on WordPress and I have all the listings on a MLS that is based on RETS (which is very old I know).
I found a plugin that would copy all the listings I need from the RETS server to an external database and then give the API key for this database.
I’m using Houzez theme which provides multiple cool features for real estate. My question is, how can I import the listings that I have from the external database to the WordPress database so I can be able to use the features of Houzez theme on the data from the external database?
