What is IDX Service?
Internet Data Exchange, or IDX, is the system that allows consumers to search for and view listings from a designated area on your website.
IDX data contains Active, Pending, and Sold listings (sold data from Jan 1, 2012).
IDX website is different than agents searching on the MLS. MLS agent-only information, such as agent remarks or showing instructions, will not show up in an IDX search.
