Step-by-Step Integration

Ce contenu n’est pas encore disponible dans votre langue.

This guide walks you through the complete process of integrating the fiskaly SIGN IT API for Italian fiscal compliance, using a combination of the fiskaly HUB and API requests. By the end, you will have a fully working System with Records being transmitted to the Agenzia delle Entrate (AdE).

Integration Workflow

The diagram below illustrates the workflow and highlights the essential steps necessary to successfully complete your integration. Each tile links directly to the matching setup step below.

⚠️Important

Steps marked in yellow must be completed directly on HUB, while the remaining steps must be handled via the SIGN IT API. Performing each action in the right context is an important step toward a successful integration.

Prerequisites

📘Before you begin

You will need a tool to make HTTP requests — such as cURL (command line), Postman, or your own application code. A basic understanding of REST APIs and authentication flows is recommended.

You may also download our Postman collection for SIGN IT, which includes pre-built requests for every step in this guide.

Before getting started, take a look at the overview of what you’ll be configuring.

Step-by-Step Setup

Register on HUB
Begin by registering on the fiskaly HUB.
For more guidance on getting started, head to our HUB - First steps section.
Create Account & Organization GROUP
Creating a fiskaly Account is the first step, after which you can proceed with setting up the first organizational structure for your business and generating your API Key.
The Account represents the PoS provider or a retailer that operates its own PoS system. It is the top-level organization in the structure.
After creating your fiskaly Account, you will be taken to the Organization Selector where you can create your Group. A Group is an intermediate level within an Account that helps you organize multiple Units into logical clusters.
Create API Key
The next step is to generate an API Key for your Organization via HUB within your Group.
You will receive an API Key and API Secret. Save these securely — you will need them to authenticate in the SIGN IT API and create your Organization(s) of type UNIT (step 5). The API Secret is only shown once. Make sure to save it securely before closing the dialogue.
💡TEST vs. LIVE environments
API Keys generated in the TEST environment (https://test.api.fiskaly.com) will create TEST resources, while those from the LIVE environment (https://live.api.fiskaly.com) will create LIVE resources. For further details, refer to our article on TEST and LIVE environments.

Create Token
Starting from this step, you will be using the SIGN IT API.
Call the createToken endpoint with the API Key and Secret from step 3 to obtain a bearer token. Include this token in the Authorization header of steps 5 and 6.
curl -X POST https://test.api.fiskaly.com/tokens \ -H "Content-Type: application/json" \ -H "X-Api-Version: 2026-05-04" \ -d '{ "content": { "type": "API_KEY", "key": "your_api_key", "secret": "your_api_secret" } }'
Example response (200 OK)
{ "content": { "id": "6f1c5c9e-3d9c-4f8c-9f20-7de8f3a91b11", "authentication": { "type": "JWT", "bearer": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...", "expires_at": "2026-03-02T12:00:00Z" }, "organization": { "id": "b7b6f971-5a3c-4e1e-9f58-2f2a8457bb2d" }, "subject": { "id": "2d4a0c2a-c2c9-4e3b-a0e8-b8f7e70d6f33" } } }

Create Organization `UNIT`

Create an Organization of type UNIT via the createOrganization endpoint. A UNIT represents a single legal entity (merchant). You will need to create one Organization UNIT for each taxpayer representation you manage.

Using the bearer token generated in Step 4 with the API Key and Secret created for your Group ensures the UNIT is correctly nested under that Group in the hierarchy.

curl -X POST https://test.api.fiskaly.com/organizations \
  -H "Content-Type: application/json" \
  -H "X-Api-Version: 2026-05-04" \
  -H "X-Idempotency-Key: $(uuidgen)" \
  -H "Authorization: Bearer ${ACCESS_TOKEN}" \
  -d '{
    "content": {
      "type": "UNIT",
      "name": "My Retail Store"
    }
  }'

const response = await fetch(
  "https://test.api.fiskaly.com/organizations",
  {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "X-Api-Version": "2026-05-04",
      "X-Idempotency-Key": crypto.randomUUID(),
      "Authorization": `Bearer ${accessToken}`,
    },
    body: JSON.stringify({
      content: {
        type: "UNIT",
        name: "My Retail Store",
      },
    }),
  }
);

const organization = await response.json();
const organizationId = organization.id;

Example response (201 Created)

{
  "content": {
    "id": "9a746f13-0ef7-4a0f-a7df-8e52089c5f3a",

    }
  },
  "metadata": {
    "trace_identifier": "trace_abc123",
    "api_version": "2026-05-04"
  }
}

Create Subject (API Key)

Create a Subject of type API_KEY for the Organization UNIT via the createSubject endpoint.

To associate the Subject (API Key) with your UNIT, include the X-Scope-Identifier header set to the id of the Organization UNIT in your request.

curl -X POST https://test.api.fiskaly.com/subjects \
  -H "Content-Type: application/json" \
  -H "X-Api-Version: 2026-05-04" \
  -H "X-Idempotency-Key: $(uuidgen)" \

  -d '{
    "content": {
      "type": "API_KEY",
      "name": "my-api-key-03"
    }
  }'

const response = await fetch(

        name: "my-api-key-03",
      },
    }),
  }
);

const subject = await response.json();
// Save the returned key and secret for the next step

Example response (201 Created)

{
  "content": {
    "id": "2d4a0c2a-c2c9-4e3b-a0e8-b8f7e70d6f33",

    }
  },
  "metadata": {
    "trace_identifier": "trace_abc123",
    "api_version": "2026-05-04"
  }
}

Create Token

Create a token using the Subject API Key and Secret you just generated. This bearer token will be used for all subsequent steps to create resources within the corresponding Organization UNIT.

curl -X POST https://test.api.fiskaly.com/tokens \
  -H "Content-Type: application/json" \
  -H "X-Api-Version: 2026-05-04" \
  -d '{
    "content": {
      "type": "API_KEY",
      "key": "subject_api_key",
      "secret": "subject_api_secret"
    }
  }'

const tokenResponse = await fetch(
  "https://test.api.fiskaly.com/tokens",
  {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "X-Api-Version": "2026-05-04",
    },
    body: JSON.stringify({
      content: {
        type: "API_KEY",
        key: "subject_api_key",
        secret: "subject_api_secret",
      },
    }),
  }
);

const { access_token: unitToken } = await tokenResponse.json();

    }
  },
  "metadata": {
    "trace_identifier": "trace_abc123",
    "api_version": "2026-05-04"
  }
}

Create Taxpayer

Now you are ready to create the operational parts required for fiscalization in Italy.

Use the createTaxpayer endpoint to add Taxpayer information to the Organization UNIT you previously created:

Set the Taxpayer as type COMPANY (legal entity) or INDIVIDUAL (natural person). In both cases, the name and the address must be provided.
Within the Italian fiscalization information, the following taxpayer data must be provided:
- tax_id_number: Italian Fiscal Code (Codice fiscale) of the business
- vat_id_number: Italian VAT Number (Partita IVA) of the business
- credentials: PIN, password, and tax ID number of the Fisconline user required to access AdE’s services

}

📘Note

Only Fisconline credentials are valid for using SIGN IT lite. The taxpayer must manually do an initial log in to the Revenue Agency’s web portal in order to ensure that the credentials work properly and to accept the terms, conditions and additional clauses provided.

⚠️Credentials renewal required

Fisconline credentials expire every 90 days on the AdE portal, though we recommend renewing them every 60 days as a best practice. Learn how in this article: SIGN IT - How to update the FISCONLINE credentials

For more information, please refer to our Credentials section.

For a detailed Merchant Guide on how to request Fisconline credentials, please contact our sales team.

Create Location

For each operating business location, you need to create a Location of type BRANCH via the createLocation endpoint.

    "store_code": "STORE001"
  }
}

Once a Location is created, its state is set to ACQUIRED by default. Update the state to COMMISSIONED using the updateLocation endpoint before proceeding.

📘Note

If the taxpayer operates from a single business location that coincides with the legal address, creating a Location::BRANCH is not mandatory. A Location::HEAD_OFFICE is automatically created upon Taxpayer creation and shares the same UUID as the Taxpayer. When the Taxpayer is set to COMMISSIONED, the Location::HEAD_OFFICE is automatically set to COMMISSIONED as well.

Create System (`FISCAL_DEVICE`)

The createSystem endpoint allows you to create an abstraction of every Electronic Recording System (ERS) used for fiscal operations. Every cash register or point of sale needs to be provided as a new System of type FISCAL_DEVICE.

A System will be connected to a specific, previously created Location.
For each System, you must provide producer and software information to track which device is performing fiscal transactions. For more information, refer to this FAQ article.

Once a System is created, its state is set to ACQUIRED by default. To create Records, its state must be updated to COMMISSIONED using the updateSystem endpoint.

⚠️Billing warning

Billing begins as soon as a System is commissioned in the LIVE environment — at which point it will also start transmitting official invoices to the financial authorities.

No billing or real transmissions take place in the TEST environment.

Create a Record

For each business operation carried out in the System, the createRecord endpoint must be used in two subsequent calls:

Part A) INTENTION: records the intention to start a TRANSACTION
Part B) TRANSACTION: provides the transaction data

Part A) Create the Intention

A Record of type INTENTION contains the association with the System that will carry out the transaction and an Operation of type TRANSACTION, representing the System’s intent to record a transaction.

    },
    "type": "INTENTION::TRANSACTION"
  }
}

Part B) Create the Transaction

A Record of type TRANSACTION is associated with the previously created INTENTION and can carry out one of the following operations:

RECEIPT: Represents the sale of a good or service, including document details (e.g. document number, total amounts including and excluding VAT) and line items (identification of a SALE, description, whether it is a GOOD or SERVICE, etc.).
CORRECTION: Represents a return process. Contains the same data as a RECEIPT operation, plus a reference id to the original RECEIPT document.
CANCELLATION: Used to invalidate an entire transaction. Requires the id of a previously created record.

Once the transaction is properly recorded and the commercial document information is successfully transmitted to AdE’s web portal (state COMPLETED, mode FINISHED), the compliance.data returned in the API response includes the progressive number assigned by AdE to the commercial document (DCW number) and, if provided, the consumer’s Lottery Code.

Note: Should a REJECTED or FAILED state be returned instead, please refer to our Record States and Modes section for further guidance.

📘Note

Records created in the LIVE environment are transmitted to the Tax Authorities and generate valid commercial documents. Therefore, these documents must always reflect actual transactions.
