Dear ZATCA Team,

We have recently started receiving the following warning during both the Onboarding and Document Submission flows:

"warningMessages": [
  {
    "type": "WARNING",
    "code": "invalid-digital-signature",
    "category": "SIGNATURE_ERRORS",
    "message": "The certificate in the invoice implies that it was signed with a private key different from the one associated with this device",
    "status": "WARNING"
  }
]

This warning appears only for Simplified Invoices in both Onboarding Compliance and Reporting API calls. It has started occurring for new onboardings as well as for previously onboarded entities that were functioning without this warning for reporting APIs.

Kindly investigate this issue.

Best regards

Hi Fatoora team / @Ankit.K.Tiwari please advise even we receive this warning

@MalikRawabi986077683 @EslamSamiH @Mreda100 @dev.cksatc if you are receiving a “warning”, then this validation was intended to inform the taxpayers who use a different private key for signing the invoices than the one generated along with the PCSID. You must make sure to use the same private key that was generated along with certificate for signing invoices.

Hello Mr. Ankit,

we are getting this error since yesterday for our stores which was reporting all invoices successfully earlier, but since yesterday 8 PM we are not able to report simplified invoices

due to this error.

{“validationResults”:{“infoMessages”:[{“type”:“INFO”,“code”:“XSD_ZATCA_VALID”,“category”:“XSD validation”,“message”:“Complied with UBL 2.1 standards in line with ZATCA specifications”,“status”:“PASS”}],“warningMessages”:,“errorMessages”:[{“type”:“ERROR”,“code”:“invalid-digital-signature”,“category”:“SIGNATURE_ERRORS”,“message”:“Invalid digital signature”,“status”:“ERROR”}],“status”:“ERROR”},“reportingStatus”:“NOT_REPORTED”}

we didn’t change anything in generating our invoices or reporting procedures, in fact some invoices of yesterday reported and some not.

awaiting your reply. please

lot of customers are facing same issue.

@SalmanKhan new validation was intended to return a warning to those taxpayers who use a different private key for signing simplified invoices than the one generated along with PCSID.
