Hi Kaushal,
Maybe next time include the response in a txt file and attached it? This post ins now reaaaally long to scroll.
I noticed you are using localhost in your URL? How you think that will work?
OutSystems needs access to your local host.
If you are running OutSystems in the cloud (PaaS) how will it able to connect to your local computer?
If you are running OutSystems on premise (your company private or virtual private network) how will that network be able to connect to your localhost?
Try running the API from a location that is accessible from OutSystems.
Regards,
Daniel
