I'm sure this will come down to some misunderstanding on my part.
I can make an API call to my store and get the results to show up in my browser window and in Postman. But when I try to make the call using some C++ code I wrote I get an HTTP response code of 200 but I don't get the JSON as I expected to.
When testing my code with a placeholder API like
https://jsonplaceholder.typicode.com/posts
It works just fine.
Am I missing something obvious? Is the xCart API different somehow?
If anyone has more experience than me and could help me out I would be greatly appreciative.
