When I try to call from Windows Forms I get an error: Underlying connection closed: Unexpected error during a send operation.. Who can help me?
Hello,
I suggest that you first manually test the API with an HTTP client such as postman.com. For any questions related to programming, Google would help you. I am sorry that I cannot help you with coding.
Regards.
