Caution
As of March 2023, all access to RETS URLs using the non-secure "HTTP" will be disabled.

Issues? Please ensure the following:

  • The RETS URL syntax is "mlsid-rets.paragonrels.com" where "mlsid" is the MLS/Board ID. Previously was "mlsid.rets.paragonrels.com"

  • All applications and libraries use TLS 1.2.

  • Password case is correct, as HTTPS is case sensitive.

  • Base authentication is being used, and not Digest authentication.
