Import a Tax Report from an XML file If the creation of the Tax Report is successful, the response of this action will already contain the QR code and the identifier for the Tax Report. Note that if the XML file has chaining information (eg Huella for Verifactu), this information will be ignored and our system will perform the chaining process regardless. This is the only way to ensure the integrity of the data sent to the Tax Authority. Remember that you have to check the status of the tax report that we send in your behalf in order to be able to take the necessary actions in case any error or warning is issued by the Tax Authority. Because of the asynchronous nature of the tax report sending process, there is no guarantee that when you check the status of the tax reports it will already have the response of the Tax Authority. It usually takes a few seconds to complete the transaction. You will know that the transaction is complete if the response of the check of the status of the tax report has an status registered, registered_with_errors*, or error. We recommend you retry the status check until you get a final state on your tax report, or that you configure WebHooks for tax report state changes.
