SDK, web-based validator and sandbox

Just use xml from Sample SDK to test. Its compliance with UBL2.1 and you can focus to get How to Signing Invoice.

If you just need to get Invoicehash, Signing Invoice, and Create Request Api for SignedDocument, you can simply use .Net Zatca.EInvoice.SDK.

Let me share the sample code.

  • Add Zatca.EInvoice.SDK and Zatca.EInvoice.SDK.Contracts as Assembly Reference
  • Add Rules files to your project folder.
...repos\ZatcaWithSDK\ZatcaWithSDK\Data\Rules\schematrons\20210819_ZATCA_E-invoice_Validation_Rules.xsl 
...repos\ZatcaWithSDK\ZatcaWithSDK\Data\Rules\schematrons\CEN-EN16931-UBL.xsl
  • Then you need cert.pem, ec-secp256k1-priv-key.pem and Simplified_Invoice.xml to test the SDK (i use this folder C:\Tmp\SdkTest\ for all myFiles)

                RequestResult RequestResult = RequestGenerator.GenerateRequest(result.SignedEInvoice);

                if (RequestResult.IsValid)
                {
                    RequestResult.SaveRequestToFile(jsonPath);

        public static void ShowSignResult(SignResult signResult)

            foreach (var step in signResult.Steps)
            {
                Console.WriteLine($"Step: {step.StepName}");

                if (step.ErrorMessages.Any())
                {
                    Console.WriteLine("  Errors:");
                    foreach (var error in step.ErrorMessages)
                    {
                        Console.WriteLine($"    - {error}");
                    }
                }

                if (step.WarningMessages.Any())
                {
                    Console.WriteLine("  Warnings:");
                    foreach (var warning in step.WarningMessages)
                    {
                        Console.WriteLine($"    - {warning}");
                    }

            }

            Console.WriteLine();
            Console.WriteLine($"Overall Sign Result: {(signResult.IsValid ? "Valid" : "Invalid")}");
            Console.WriteLine();
        }

    }
}

This work good.

I am waiting for someone to provide a code example, how to validate Invoice using .Net Zatca.EInvoice.SDK Library.
So far I have not managed to do it. :slight_smile:
