The service allows you to send fiscal receipts to the Italian Revenue Agency (Fatture e Corrispettivi) quickly and securely, increasing efficiency and reducing costs. The API solution does not require a subscription fee, and the cost per invoice starts from €0.009.
The service is designed to meet all customer needs, such as sending receipts (online commercial document), cancellations, returns, discounts, and different payment methods (e.g., meal vouchers or cash payments). Receipts are transmitted in real-time and managed until a positive response is received from the Revenue Agency.
The adoption of electronic receipts eliminates the obligation to keep a register of receipts and store copies of commercial documents issued to customers (as was previously required, for example, with fiscal receipt copies), optimizing costs and operational time.
Electronic Receipt is part of API Invoice, the new API designed to make invoicing services available not only at the Italian level but also at the European and international levels.
Our solution integrates seamlessly with existing management systems, ensuring compliance with Italian regulations and efficient handling of fiscal documents. It is possible to configure and manage the transmission of receipts for multiple companies (Business Registry Configuration).
BUSINESS CONFIGURATION (COMPANY DATA)
In the first request, it will be necessary to set up the company data of the business that wishes to send fiscal receipts. For third-party integrators, the end customer's information must be provided, specifically:
- Fiscal Code
- Company Name
- Revenue Agency Authentication Data (Fiscal Code, Password, PIN)
- Specific event notifications
The tax code must belong to the person responsible for sending the electronic receipts on behalf of the company and must match the one set in the Private Area of the Revenue Agency. For more details, we recommend consulting the dedicated guide.
CONFIGURATION REQUEST EXAMPLE
POST /IT-configurations
The request must be made by referring to the following endpoint and passing the company's fiscal code:
https://invoice.openapi.com/IT-configurations/{fiscal_id}
In the payload, it will be necessary to include the previously mentioned data:
{
"fiscal_id": "string",
"name": "string",
"email": "string",
"receipts": "true",
"supplier_invoice": false,
"legal_storage": false,
"signature": false,
"receipts_authentication": {
"taxCode": "XXXXXXXXXXXXX",
"password": "1234567891****d",
"pin": "1********4"
},
"api_configurations": [
{
"event": "receipt",
"callback": {
"url": "https://your-server.site/123232"
}
},
{
"event": "receipt-error",
"callback": {
"url": "https://your-server.site/error"
}
}
]
}
At this stage, it is essential to set the receipt service to true to activate the electronic receipt submission service.
Existing company configurations can be updated at any time via a PATCH request by passing the fiscal code.

The Electronic Receipt Service is an API that enables the sending of commercial documents in a simple, fast, and secure manner. With this solution, you can manage the real-time sending of electronic receipts, even for high volumes, and handle operations such as cancellations, returns, discounts, and different payment methods (e.g., meal vouchers and cash payments). This service is part of the Invoice API, a new API designed to provide billing solutions not only in Italy but also across Europe and internationally.
The Electronic Receipt API is the ideal solution for simplifying and modernizing the management of fiscal documents. With rapid, flexible, and secure integration, it allows the automation of receipt sending, ensuring full compliance with current regulations.
It is perfect for businesses such as retail chains, large-scale distribution (GDO), and management software that want to optimize operational workflows, reduce paper usage, and minimize errors, all while speeding up processing times.
Current regulations do not require issuing a copy of the receipt to the customer. However, it is possible to use the data available in the response to generate a PDF that can be sent digitally or printed.
The service is provided in real-time. However, if there are any issues on the Italian Revenue Agency’s side, the submission will remain in the queue until the operation is successfully confirmed.
The Electronic Receipt Service has no activation costs. Fees vary based on usage: for each request of sending, cancellation, or return, the cost starts at €0.009 for subscription-based usage or €0.019 per single request with credit.
The choice between issuing an invoice or a fiscal receipt mainly depends on the type of customer and the nature of the transaction:
-
Business or professional client (B2B):
- Mandatory invoice: When the customer is a business, a professional, or an entity (i.e., has a VAT number), the law requires the issuance of an invoice. This is because such entities need to deduct VAT or correctly account for costs.
- Electronic invoice: In transactions between entities based in Italy (and for transactions with public administrations), regulations require the use of electronic invoicing.
-
Private customer (B2C):
- Fiscal receipt: For retail sales to final consumers who do not have a VAT number, a fiscal receipt issued via an authorized cash register is generally sufficient.
- Invoice upon request: If the private consumer explicitly requests an invoice (e.g., for warranty purposes or other reasons), the supplier is required to issue one, even if the transaction involves a final customer.
Yes, an API service (SdI) is available for sending and receiving electronic invoices for businesses and public administrations.
Yes, the service is fully integrable for third parties. However, to activate it, the access credentials of the subject sending the receipts are required from the Italian Revenue Agency.
The APIs offered by Openapi fall within the services defined by the Italian Revenue Agency as "Velocizzatori" (Accelerators).
In addition to complying with all the guidelines set by the Revenue Agency, customer credentials (in accordance with regulations) are not stored by Openapi. Instead, only their fingerprint is saved (a one-way encoding that does not allow credentials to be understood but only verifies if they have changed).
Therefore, credentials are always managed exclusively by the user, who uses them within the "accelerator" to complete the submission or reading of the transaction data.
For more details, please refer to the official note from the Italian Revenue Agency.
Yes, in order to issue receipts it is necessary to log on to the Italian Revenue Agency.
