How to succeed with your Fatture In Cloud API integration project

Fatture in Cloud is a widely adopted invoicing platform in Italy, used by freelancers, SMEs, and accounting professionals to issue invoices, manage VAT, and stay compliant with local regulations.

If your product operates in finance, invoicing, accounting automation, cashflow, or payments, integrating with Fatture in Cloud gives you direct access to structured, compliant invoicing data from one of the Italian market’s key players.

In this article, we’ll cover how the Fatture in Cloud API works, how to set up an integration, best practices to follow, and how Chift simplifies everything through a unified invoicing layer.

What is the Fatture in Cloud API?

The Fatture in Cloud API is a modern RESTful API designed to programmatically access invoicing, tax, and entity data stored in a Fatture in Cloud account.

Technical overview

• API type: REST (v2 – current and recommended)
• Base URL: %%https://api-v2.fattureincloud.it%%
• Protocol: HTTPS
• Data format: JSON
• Specification: OpenAPI (YAML available)

Multiple API versions

• API v2 (recommended)
• Fully REST-compliant, supports OAuth2, and covers all invoicing and entity use cases.
• API v1 (legacy)
• Older POST-only design, now deprecated. Migration to v2 is strongly encouraged.

Chift uses API v2, ensuring secure OAuth2 authentication and long-term compatibility.

How to set up a Fatture in Cloud API integration

Integrating with Fatture in Cloud requires an OAuth2-based setup.

Prerequisites

1. An active Fatture in Cloud account
2. API access enabled on the company account
3. An application created in the Fatture in Cloud interface
4. A Client ID and Client Secret

Setup steps

• Log in to the Fatture in Cloud web interface
• Go to the Developer section
• Create a new application and retrieve credentials
• Define the Redirect URL for the OAuth2 flow
• Use OAuth2 Authorization Code Flow with the required scopes, including:
  • %%entity.clients:r%%
  • %%entity.suppliers:r%%
  • %%products:r%%
  • %%issued_documents.invoices:r%%
  • %%issued_documents.credit_notes:r%%
  • %%received_documents:r%%
  • %%taxes:r%%
  • %%settings:r%%

Chift handles this entire flow for you, including token storage, refresh logic, and scope management.

Best practices for integrating with the Fatture in Cloud API

To ensure a secure, scalable, and reliable integration, we recommend the following:

• Handle authentication securely
  • Always use OAuth2 Authorization Code Flow
  • Never expose the Client Secret in frontend code
  • Store credentials in environment variables or secure vaults
  • Use refresh tokens to renew access automatically
• Respect rate limits and handle errors properly
  • Implement exponential backoff for %%429 Too Many Requests%%
  • Read and monitor rate limit headers
  • Use %%Retry-After%% to schedule retries correctly
  • Do not retry %%403 Forbidden%% errors without addressing quota limits
• Optimize performance
  • Batch requests when possible
  • Cache static data such as company IDs
  • Use pagination for large datasets
  • Reuse HTTP connections for better efficiency

Chift applies these best practices by default, so you don’t need to rebuild them for every integration.
