Connecting to RETS through Fiddler/Postman

[DJOHN4]

HI Davisson,

I am trying to connect to RETs server using postman/fiddler.
All works well with https://retsmd.com/, however, it is never successful from fiddler or postman.
I have a website for my client which is written in .Net and java services. I want to call MLS DB to get data from .net/java class.

How can I do this?
I have below details from my MLS provider.

Login URL: https://rets2.gsmls.com/rets_idx/login.do
UserName: ######
Password: ######
User-Agent: ########
User-Agent Password: ####

I suspect I am not passing the right header values. I always get below error from postman/fiddler

I would recheck the User-Agent and set it to Fiddler Everywhere so that the server can identify the request sender. Also, double-check the conventions followed for the key-value pairs like username, password etc.
