We were recently give the following info for what appears to be a new WebAPi interface for Paragon:

New Paragon Login: smlsaConstellationWS New RETS Web API: Web API Metadata:

It doesn't appear to be a standard implementation compared to other vendors as we would normally also expect to receive an auth token and auth url. Can you point me to some documentation on how to use this system?

Hi Paragon Support, Following up on the above message. Do you have any API Documentation for our developers to use to code to the new API Feed?

We're also looking for API documentation, if that's available.

Add my name to the list of folks needing some documentation...getting errors when requesting an access_token and would like some real-world examples to use besides the info sent to us my the MLS which seems incomplete.

Hi, did anyone receive any documentation? Or can you please share any sample query/URL/examples to get property data ?

Much appreciated. Thanks!

Following up on this comment, is there any user documentation available for the webAPI yet? We have credentials to Paragon APIs, but our developers need to know more information since all API platforms that are supposed to be RESO standard have their own custom nuances.

There is a link to the RESO documentation on GitHub on the top right side of the Vendor Support site.

That link sends us to a page that is no longer supported. I receive a 404 error -

Try again. It should work now.
