Openapi Invoicing

Openapi invoicing & payments

Bearer token required (see the openapi-auth skill). Sending invoices/receipts to the Revenue Agency and paying bills are irreversible fiscal/financial actions — always confirm with the user first.

Invoice (preferred) — https://invoice.openapi.com

Full management of Italian electronic invoices (FatturaPA XML) and digital receipts.

• POST /IT-invoices — create/send an invoice to the SDI; GET /IT-invoices, GET /IT-invoices/{id} — list and monitor states (delivery, rejection)
• POST /IT-invoices_import — import externally created invoices
• POST|GET|PATCH|DELETE /IT-configurations[/{fiscal_id}] — per-company configuration (signature, legal storage, receipts_authentication)
• POST /IT-receipts — send a digital receipt; GET|PATCH|DELETE /IT-receipts/{id} (PATCH returns items from a receipt)

Key constraints:

• Receiving supplier invoices requires registering Openapi's Recipient Code on the Revenue Agency website: code PIC7CPS (Invoice API).
• Receipts cannot be sent 23:55–00:00 Italian time (queued to the next day); the receipt service requires enabling third-party credentials on the Agenzia delle Entrate portal (guide: https://docs.openapi.it/Procedura-manuale-per-incarico.pdf). Freelancers/sole proprietorships cannot delegate and must use their own credentials.

SDI (lower-level) — https://sdi.openapi.it

1. POST /business_registry_configurations (fiscal_id + email; legal-storage registration email follows)
2. POST /api_configurations — set callbacks for notifications
3. POST /invoices — send XML invoice; variants /invoices_signature, /invoices_legal_storage, /invoices_signature_legal_storage
4. GET /invoices/{uuid}, GET /invoices_download/{uuid}, GET /invoices_notifications/{uuid}
5. Imports: POST /customer_invoice_imports, POST /supplier_invoice_imports (+ _legal_storage variants); test with POST /simulate/{type}

Recipient Code for SDI API: JKKZDGR. If the wallet runs dry the configuration is suspended — reactivate with PATCH /business_registry_configurations/{fiscal_id}/activate after recharging. PA invoices are auto-detected and signed.

Paying Bills — https://ws.pagasubito.it

Pay bollettini, MAV, RAV, PagoPA and car tax (bollo auto) via API in real time.
