Verifactu

Verifactu is a standarized digital format for submitting all invoices issued in Spain. Write us a line at developers@quaderno.io to be part of our beta program!

Thanks to our API, complying is as easy as sending your sale or refund data to Quaderno in a single API call. You will receive a JSON response with the signed PDF of the document, which contains a QR code to ease later verification.

Sending sales and refunds data​

Send your sales and refund data to Quaderno as usual using our Transactions API. This will enable other benefits, such as up-to-date tax reports and registration alerts.

These guides will guide you through the process:

When the Verifactu integration is enabled, Quaderno will automatically send all invoices and credit notes to the corresponding tax administration.

Verifactu’s verification_code and verification_url will be available from the API responses, and generated invoices will display their verification ID and a QR code, allowing your customers to confirm the status of the invoice with the respective tax administration.

Accessing Verifactu responses​

You can read Verifactu responses in all credits and invoices sent to Verifactu. The deliveries list will contain all the information, including Verifactu's error messages.

For example, retrieving an invoice with a GET call to /invoices/{id} :

curl --request GET
  --url https://sandbox-quadernoapp.com/api/invoices/92732431 \
  --header 'Authorization: Basic API_KEY' \

Will return a response with a list of deliveries.
