Vendor Support Center

Welcome to the vendor support page for ICE's Paragon MLS system. Here you'll find up to date information regarding the data transport standards supported by Paragon. Each Organization (MLS, Association or Board) chooses how to transport their data to vendors. Questions related to access, specific data product usage, and field availability should be directed to the Organization. We look forward to assisting you with your technical opportunities.

RETS

RESO has deprecated the RETS standard in favor of OData through Web API. ICE will support RETS as long as Organizations continue to use it. You'll find links to our RETS Best Practice Guide and all RESO's specifications here or this site's menu.

All RETS transactions must be done with HTTPS. Should you have issues with login, please verify the following:

URL Format: mlsid-rets.paragonrels.com
TLS Library v1.2
Basic Authentication
Username and Password, which are case sensitive

Property image retrieval best practice is through the Media resource and not GETOBJECT. The media URL's would be used to download images. Please contact Organizations if you wish to change your retrieval method. Documents, Office Logos, and Agent Photos require the use of GetObject with Location=1, to return a URL to download the media.

API

We offer two RESO Data Dictionary compliant Web API products:

OpenMLS - paragonrels.com
Property Information Central (PIC) - paragonapi.com

Please check the second level domain before reviewing a guide. RESO's format allows for different schema. For example, PIC is more object based.
