Code examples
Here is an example of a POST request in the C# programming language with a JSON message that uses client certificate authentication and adds a custom header:
This example downloads the certificate and associated private key from a file and adds it to the HttpClientHandler. It then creates an HttpClient using this handler. Next, it creates a JSON message, converts it to a string, and creates a StringContent token. It also adds a custom header "tax-softwarekey". Finally, it sends a POST request to the specified interface and prints the response.
Note that you must replace "path_to_your_certificate.pfx", "your_certificate_password", "your_software_key" and "https://your_api_endpoint" with the correct values.
