I'm working on a software who sends request to a distant API which will be develloped by a external party. The Template of the answers the API will send is known to me so I would like to find a software to anwser my GET request as a placeholder for the upcoming API, and of possible I would like this software to be able to anwser dynamicaly.
I have trouble finding Something fitting for my needs (i have found a small software able to answer static JSON answers). Maybe what i'm looking for is obvious but i have trouble looking for it as English isn't my mothertongue.
Thanks in advance
