Action Needed: RETS Charges Beginning March 2026

We're writing to remind all RETS users that beginning March 1st, 2026, FBS will charge developers $75/month for each MLS for which they have at least one RETS feed. These fees will increase by $25 every 6 months thereafter.

Before March 1, 2026, developers must link all RETS feeds they're using to a Spark developer account with valid payment on file. RETS feeds not linked to a Spark developer account by March 1st, 2026 will be subject to suspension.

See below for instructions on how to connect RETS feeds to a Spark developer account, as well as additional information about the timeline and FAQs using this button.

RETS Developer Action Items

Switch from RETS to Spark API feeds

To avoid higher fees, we strongly encourage all RETS users to switch any RETS feeds you're consuming to API feeds. This change will be required before too much longer, and by switching now, you'll be set to continue to receive data without disruption when RETS is ultimately deprecated and no longer supported. This page outlines how to set up Spark API access to MLS data.

Link all RETS feeds to a Spark developer account

To continue using RETS in March 2026 and beyond, all RETS feeds must be linked to a Spark developer account with a valid payment method. RETS feeds not linked to a developer account before March 2026 will be subject to suspension.

To link your RETS feeds to a Spark developer account, either sign up for a Spark developer account and sign in or log in to an existing one.

Next, Click the “RETS FEEDS” button near the top right.

On this screen, enter the RETS login name of each RETS feed you wish to use beyond March 2026. Be sure to also add a payment method to your Spark developer account using the link on this page.
