Standard IDX/VOW Feed

What is IDX?

IDX, sometimes referred to as “broker reciprocity," offers MLS subscribers the ability to display listings on other MLS subscribers’ Internet websites. Simply put, IDX is the set of tools and policies that govern the process of marketing real estate listings on the Internet.

KAAR MLS Subscribers Get It FREE!

KAAR is pleased to offer our MLS subscribers a FREE IDX data link, which allows consumers to search for properties listed on REALTOR® and Real Estate Brokerage websites.

Flexmls IDX Link 

You can embed the free Flexmls® link directly on your website. To retrieve the link, log in to Flexmls®, go to Preferences then IDX Manager and scroll down to "Click here to get IDX 2.0 lite." The link will appear in the box to the right and may be copied from there.  

You will also notice Flexmls® offers a number of upgrades for that link, which you may purchase directly through FBS. For more information, contact 800-437-4232 ext. 108 or e-mail  

VOW (Virtual Office Website) 

Through a VOW, a participant can provide real estate brokerage services to consumers with whom he/she has established a broker-consumer relationship (as defined by state law). The participant’s VOW allows these consumers to search properties, which are subject to the participant’s oversight, supervision, and accountability.

A non-principal broker or sales licensee affiliated with a participant may, with his or her participant’s consent, operate a VOW. Any VOW of a non-principal broker or sales licensee is subject to the participant’s oversight, supervision, and accountability.

Standard IDX Feed

This feed contains the same information as the other two options (Flexmls and VOW); however, the Standard IDX feed is provided as raw data. Your programmer must have knowledge of the Real Estate Transaction Standard (RETS) server in order to properly embed the data on your site.  KAAR provides the Standard IDX data feed for a $250 setup fee.
