New NIFs are added through this endpoint. NIFs are used to issue Verifactu invoices. Each NIF has a unique Verifacti API Key, which Verifacti generates upon adding a new NIF.
IMPORTANT
- Verifacti API Key generation: A unique Verifacti API Key will be generated automatically when adding a new NIF. You will need this key to issue valid Verifactu invoices.
- For Ecart Pay API users: If you want to use a specific NIF for invoicing through Ecart Pay, ensure you update the corresponding key in: Integrations -> Billing Gateways -> Verifacti (Spain).
