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)
