YoFacturo
YoFacturo is a Spanish invoicing platform that lets organizations create, issue, and manage invoices in compliance with Spanish fiscal regulations, including the VeriFactu system for real-time invoice synchronization with the Spanish tax authorities (AEAT).What you can do with the API
The YoFacturo API v1 allows external systems and integrations to:- Submit invoice batches — send up to 1,000 invoices per request for asynchronous processing and issuance.
- Track batch status — poll the status of submitted batches and inspect the processing result of each individual invoice.
- Monitor VeriFactu synchronization — check whether each invoice has been synchronized with Spain’s VeriFactu fiscal system.
