We are facing an issue with B2C Invoice validation with ZATCA SDK 3.3.0

The Signing process done by latest SDK but i am getting the following error message when Validate it ZATCA SDK Offline

“[Error] CODE: xadesSignedPropertiesDigestValue, MESSAGE: wrong xadesSignedPropertiesDigestValue”

But When I test the same XML File on ZATCA Web Validator. i am getting multiple error message as attached.

I am doing the following process.

  1. Generate the XML with ZATCA Requirement
  2. Sign the XML with New SDK 3.3.0
  3. The Signed XML get from Signing process pass it into Validation process. But validation failed with the above highlighted error message.

Hi All,

After working two weeks on the issue, It get resolved by applying following changes in the XML File before validation.

public void SetDigistProperty(string XMLFilePath, string Certificate, string PrivateKey)
{
XmlDocument XMLDoc = new XmlDocument();
XMLDoc.Load(XMLFilePath);
string STR = SharedUtilities.GetNodeInnerXML(XMLDoc, Zatca.EInvoice.SDK.Utilities.ConfigurationManager.ConfigurationManager.SIGNED_PROPERTIES_XPATH).Replace(" />“, “/>”).Replace(”></ds:DigestMethod>“, “/>”);
var SIGNED_Properities = SharedUtilities.EncodeToBase64(SharedUtilities.HashSha256AsString(STR.Replace(”\r", “”)));
SharedUtilities.SetNodeValue(XMLDoc, Zatca.EInvoice.SDK.Utilities.ConfigurationManager.ConfigurationManager.SIGNED_Properities_DIGEST_VALUE_XPATH, SIGNED_Properities);
XMLDoc.Save(XMLFilePath);
}

Please Note:
1: Here I am passing the Singed XML File which having UBL Extensions Tags
2: Forget about the Web Validator in B2C it will give you error anyway but after applying the above changes. Offline and ZATCA API validation got passed without any errors
