Listify IDX can bring ARMLS listings onto your website with a map, filters, and a page for every listing. ARMLS delivers data through its RESO Web API on the Spark platform and issues the keys itself. Your brokerage signs an ARMLS Content License Agreement, and ARMLS includes several data feeds per brokerage at no charge. Once you sign up, we set up the connection with you.
- Provider type
- Statewide MLS
- Feed
- RESO Web API on the Spark platform, with keys from ARMLS
- Plans
- Plus and higher
- Coverage
- The entire state of Arizona.
How the ARMLS connection works
ARMLS (Arizona Regional Multiple Listing Service, Inc.) is owned by four REALTOR associations: Phoenix REALTORS, the Scottsdale Area Association of REALTORS, the Sedona Verde Valley Association of REALTORS, and WeSERV. Its rules set its service area as, at a minimum, the entire state of Arizona.
ARMLS delivers listing data through its RESO Web API, which runs on the Spark platform. ARMLS issues API keys directly, rather than through the Spark Datamart, and it ended RETS, an older feed format, in December 2023. ARMLS holds current RESO certification.
ARMLS leaves compensation fields out of its data feeds, so your search never shows what one brokerage offers another.
How to get connected
- Your brokerage signs a Content License Agreement. ARMLS licenses IDX data to its participants and their subscribers. An agent’s website needs the participant broker to sign the license along with the agent.
- Apply through ARMLS’s intake forms. ARMLS takes every new data feed application through online intake forms. Its data feeds page explains who may apply.
- ARMLS issues the API key. Once approved, ARMLS issues the key for the feed, as its API page describes.
Once you sign up, we set up the ARMLS connection with you. ARMLS handles its data access approval, and we handle the rest.
ARMLS may charge its own MLS data fees for access to your listing data. It includes five data feeds per brokerage at no charge, not counting VOW feeds, then charges a monthly fee per extra feed, and its policy says feeds may also carry a set-up charge. Those fees are set by ARMLS, are separate from your Listify IDX subscription, and are paid by you. We never mark them up. See our Terms of Use.
What visitors see on your website
ARMLS’s IDX rules (Section 23 of its rules) are some of the most specific about the page itself:
- ARMLS as the source on every listing, with the listing firm and its email or phone number, in text as large as the rest of the listing.
- ARMLS’s notice on the site: “All information should be verified by the recipient and none is guaranteed as accurate by ARMLS.”
- No Coming Soon, expired, or canceled listings. ARMLS doesn’t allow them on IDX websites.
- Private details stay private. Sellers can withhold a listing or its address, and confidential fields, the type of listing agreement, and seller or occupant contact details never appear.
We set up your search to meet these rules when we connect your feed.
What you need
- An ARMLS subscription, and your participant broker’s signature on the Content License Agreement.
- Your brokerage name at the top of every page. ARMLS requires it on your front page and every page after, visible without scrolling on any screen. A team name must read clearly as part of your brokerage.
- A website where you can add your own code. Any website builder with a code embed or custom HTML block works.
- A Listify IDX account on the Plus plan or higher, which includes MLS feeds.
Works on the website you already have
Listify IDX adds property search to the website you have now. You or your web team copy and paste a single piece of code, called an embed code, into the page, and the search appears there. See the steps for Webflow, Squarespace, Wix, WordPress, Showit, or any other website.
