Hello @idaoud , thank you. A related clarification: Am I correct to understand that if the system could not get any response due to a timeout but recieved a 409, then a 200 ‘PASS’ should be issued in the system to close the resend loop. Additionally, if a 208 was recieved under the same circumstances (+ no signed XML being stored in the system since no response was recieved due to a system timeout), then a 200 ‘PASS’ should still be issued by default in the system to close the resend loop but the taxpayer should create a credit note and then reissue this invoice to get the Signed XML. Edit: I was mistaken, the response 208 will include the signed XML: [Breaking Change: Checking the duplicate (response codes 208 & 409)](https://zatca1.discourse.group/t/breaking-change-checking-the-duplicate-response-codes-208-409/6859) cc: @Ankit.K.Tiwari --- _[View the full topic](https://zatca1.discourse.group/t/409-status-code-duplicate-invoice-error/3932)._
