IDX Broker Integration

IDX Broker is the most common MLS data provider for real estate websites. ARIS connects directly to IDX Broker’s API to search listings in real time.

​
Setup

1

Log in to IDX Broker

Open your IDX Broker dashboard
2

Get your API keys

Go to API → Access and copy your API Key (access key). Note your Ancillary Key if you have one.
3

Connect in ARIS

In the ARIS dashboard, go to MLS Sync → IDX Broker and enter both keys.
4

Save

ARIS automatically syncs your listing data and begins serving it through the widget.

​
What ARIS uses from IDX

​
API reference

ARIS uses the following IDX Broker API methods:
  • Client results — property search by city, price, beds, etc.
  • Client featured — promoted listings for an agent or office
  • Component search — advanced field-level search
See the IDX Broker API docs for the full method reference.

​
Follow Up Boss

If your IDX Broker account is connected to Follow Up Boss, leads captured by ARIS are automatically synced to your CRM. No additional setup is needed.

​
Troubleshooting

  • Verify your API key is correct in the IDX Broker dashboard
  • Confirm your MLS data feed is active (check IDX MLS coverage)
  • Allow 5-10 minutes for the initial sync to complete
ARIS fetches from IDX Broker in real time on each search. If you see stale data, the issue is upstream in the MLS feed update schedule (typically 15 minutes to 4 hours depending on your MLS).
