Hi,

It should be possible to integrate with an API using mTLS from QActions or automationscript by sending the API requests via a HttpClient in C#. The implementation would look something like this:

        // Load the client certificate</span>
        X509Certificate2 clientCert = new X509Certificate2("C:\\path\\to\\cert.p12", cert_pwd);

        // Create an HttpClient
        HttpClient client = new HttpClient(new HttpClientHandler
        {
            ClientCertificateOptions = ClientCertificateOption.Manual,
            ClientCertificates = { clientCert }
        });
