[Trouble while authentication through Postman]

Hi ben, 

 

I am using from France, and am trying to connect with a fully licenced solution "Sage 50c Premium" v.4.0.0, and the user I have does have full access to Accounting. 

I am having doubts wether if the product I have is compatible with the API... Are you familiar with this product ?
