Brokers and IDX
Today most REALTORS® display their own and other Brokers’ listings on their websites through Internet Data Exchange (IDX). The ARMLS® IDX Policy
allows MLS Participants, who do not opt out of IDX, to grant and receive permission to display each other’s listings on Participant and Subscriber websites. Details on IDX, applicable rules and the displayable data fields contained in the IDX data are described in the ARMLS IDX Package
. Any website that displays the IDX listing data of other Brokers is subject to the IDX rules and policies.
There are three options available for Broker/Participants to provide MLS searching on their websites via the IDX program:
1. Brokers can use a FREE IDX frame that can be added to their website. Diverse Solutions and Success Web Systems both offer a FREE IDX FRAMING OPTION
for any active ARMLS Participant (Broker) or Subscriber (Agent) to use on their website.
2. Brokers can obtain a Real Estate Transaction Standard (RETS) access which contains public listing data. MLS data is accessed through RETS (link to Getting Started with RETS Guide) a common language used by systems that handle real estate information. This access will allow the Participant’s webmaster to design a custom MLS search for the website. (Note: the RETS access is available only to Broker/Participants, and not Agents/Subscribers.) Brokers and Web developers must complete a Participant Content License Application
to obtain a data license and RETS access.
3. Brokers can purchase a website with search functionality from an ARMLS approved website vendor, a list of which can be found in the ARMLS RE Technology catalog

Brokers interested in obtaining RETS access to MLS data for their IDX, VOW or other related real estate application should complete and submit a Participant Content License Application, which cites the Broker’s intended use for the data, and email it to firstname.lastname@example.org.
Vendors interested in RETS access to MLS data should conform to the policies set forth in the ARMLS Content Access Policy
