  • Easy interfaces for consumers, less non-listing “clutter”.
  • Visitors have the ability to search Active MLS listings on your website.

How do I get IDX?

Download Options: RETS and API

  • Effective December 1st, 2021, SWMLS no longer offers RETS as an option for new data feeds. Existing vendors with RETS feeds are encouraged to convert to API as soon as possible, as RETS will be sunset at a date in the near future.
  • Obtaining a Feed: SWMLS API data feeds are handled through Trestle. The Data Vendor that is requesting the data will need to go directly to to create or enable their API for SWMLS Data.  
  • SWMLS Members: Advise your Vendor to complete this process. You shouldn't need to do anything except sign the contract when it gets to you.
  • Data Vendors: For help with setting up a contract/feed, plus contact Trestle support at 844-530-8855 or
  • Setup Costs:  SWMLS does not charge any fees for data feeds, vendors will only pay the monthly fees charged by Trestle

*Costs are subject to change and will be reviewed frequently by the SWMLS Board of Directors.*

IDX Framing Options

  • Framing Option: The framing solution is a link to pages that can be formatted to appear like the search screen in FlexMLS, as if they are part of your existing website. If you have webmaster experience, you can use this option and insert it into your website on your own. If you already have a website and a provider/webmaster, contact that provider to get this work done for you.
  • Framing Costs: FREE. These links are available in FlexMLS by going to Preferences › IDX Manager and selecting the IDX 2.0 Lite link at the bottom of the page.
  • FLEX Paid Option:  More a more robust IDX framing option we recommend looking at the FLEX IDX options for Framing  links or their Wordpress websites.
