The MLS works with a company called IDX to handle all the data around their listings.
If you want to add MLS listings to your website, you will need to create an account with IDX. There is a cost for this. You can find pricing here: https://idxbroker.com/compare-idx
Once you have an IDX account set up, we'll be able to work with you to get your listings added to your Jottful website. Just email us at firstname.lastname@example.org .
