+	"log"
+
+	"github.com/deploymenttheory/go-api-http-client/httpclient"

+	loadedConfig, err := jamfpro.LoadClientConfig(configFilePath)
+	if err != nil {
+		log.Fatalf("Failed to load client OAuth configuration: %v", err)
+	}
+
+	config := httpclient.ClientConfig{
+		Auth: httpclient.AuthConfig{
+			ClientID:     loadedConfig.Auth.ClientID,
