Hi! I'm new working with Odoo and new developer too.

I am trying to follow the documentation on the website in order to connect to Odoo in C# and start getting information from it, however am unable to pass from the first steps. 

I have an Odoo server set up, and am trying the simplest URL like this:

http://ip:port/xmlrpc/2/common/version 

Is this the wrong way to go about it? I always get a 404 error..

I have found a way online to do the authentication on postman with the following, however no idea if this is correct as the endpoint differs from what is in the documentation:

http:// ip:port /web/session/authenticate

with the following json body:

{    "jsonrpc": "2.0",     

"params": {       

 "db": "dbname",       

  "login": "logindetails",       

  "password": "passdetails"  

  }}

 Thank you in advance for any help provided!
