So the login works fine. We tried to do sample search as per this document
URL we tried: http://mimls.rets.paragonrels.com/rets/fnisrets.aspx/mlsid/search?SearchType=Property&Class=ResidentialProperty&QueryType=DMQL2&Format=COMPACT&StandardNames=1&Select=ListingID,ListPrice&Query=(ListPrice=300000%2B)&Count=1&Limit=10
Getting 404 error for this query. Please look into this. Thanks
