Load Fatture in Cloud data to DuckDB

Fatture in Cloud is a RESTful API that provides access to the features available in the Fatture in Cloud Web interface for managing accounting and business data. Everything needed to build a working Fatture in Cloud → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your Fatture in Cloud to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

PromptCopy prompt
Run uvx dlthub-init@latest to build a pipeline from Fatture in Cloud to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the Fatture in Cloud API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.

Fatture in Cloud API at a glance

These values come from the Fatture in Cloud API reference — the authoritative source if anything here looks out of date.

How do I authenticate with the Fatture in Cloud API?

Authentication is performed by passing an OAuth 2.0 access token in the Authorization HTTP header with the Bearer prefix (e.g., 'Authorization: Bearer ').

1. Get your credentials

To obtain your API credentials, follow these steps: 1. Log in to your Fatture in Cloud account. 2. Navigate to the 'Impostazioni' (Settings) menu. 3. Locate and click on the 'Sviluppatore' (Developer) section. 4. Click the 'Nuova app' (New App) button to create a new application configuration. 5. On the application management page, select your preferred authentication method (OAuth 2.0 is recommended for most integrations). 6. Once configured and saved, the dashboard will display your 'Client ID' and 'Client Secret'. Ensure you keep the Client Secret secure and never expose it in client-side code.

2. Add them to .dlt/secrets.toml

Copy
[sources.fatture_in_cloud_source]
access_token = "REPLACE_ME"

dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.

What Fatture in Cloud data can I load into DuckDB?

These are the Fatture in Cloud endpoints dlt can load into DuckDB:

How do I load only new Fatture in Cloud records?

Fatture in Cloud exposes updated_at on c/{company_id}/entities/clients, so dlt can request only the records that changed since the last run. Set it as the cursor_path and dlt tracks the high-water mark for you between runs.

Copy
{"name": "clients", "endpoint": {
    "path": "c/{company_id}/entities/clients",
    "data_selector": "data",
    "incremental": {"cursor_path": "updated_at", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

What does the generated Fatture in Cloud pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading https://api-v2.fattureincloud.it/oauth/authorize and https://api-v2.fattureincloud.it/oauth/token from the Fatture in Cloud API into DuckDB:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def fatture_in_cloud_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api-v2.fattureincloud.it",
            "auth": {"type": "bearer", "token": access_token},
        },
        "resources": [
            {"name": "clients", "endpoint": {"path": "c/{company_id}/entities/clients", "data_selector": "data"}},
            {"name": "suppliers", "endpoint": {"path": "c/{company_id}/entities/suppliers", "data_selector": "data"}}
        ],
    }
    yield from rest_api_resources(config)


def load_fatture_in_cloud_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="fatture_in_cloud_pipeline",
        destination="duckdb",
        dataset_name="fatture_in_cloud_data",
    )
    load_info = pipeline.run(fatture_in_cloud_source())
    print(load_info)


if __name__ == "__main__":
    load_fatture_in_cloud_to_duckdb()

Run it with python fatture_in_cloud_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query Fatture in Cloud data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("fatture_in_cloud_pipeline").dataset()
df = data.clients.df()
print(df.head())

SQL:

Copy
SELECT * FROM fatture_in_cloud_data.clients LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

How do I deploy the Fatture in Cloud to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw Fatture in Cloud loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load Fatture in Cloud data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
