Load Piwik Pro data to DuckDB

Piwik PRO is an analytics and marketing suite that provides a Web API for managing, querying, and interacting with its platform data. Everything needed to build a working Piwik Pro → 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 Piwik Pro 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 Piwik Pro 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 Piwik Pro 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.

Piwik Pro API at a glance

These values come from the Piwik Pro API reference — the authoritative source if anything here looks out of date.

How do I authenticate with the Piwik Pro API?

Authentication involves two steps: first, retrieve an access token via a POST request using client_id and client_secret. Subsequently, include this token in subsequent API requests as a Bearer token in the 'Authorization' header.

1. Get your credentials

To obtain API credentials in Piwik PRO: 1. Log in to your Piwik PRO account. 2. Click on your profile icon (Menu) in the top-right corner. 3. Navigate to the API keys (or API credentials) section. 4. Click 'Create a key' (or 'Generate new credentials'). 5. Enter a name for the key and confirm. 6. Copy the generated 'Client ID' and 'Client secret' immediately, as they will not be visible again once the window is closed. These credentials are used to obtain an access token via a POST request to /auth/token.

2. Add them to .dlt/secrets.toml

Copy
[sources.piwik_pro_source]
piwik_pro_host = "your-account.piwik.pro"
client_id = "your_client_id_here"
client_secret = "your_client_secret_here"

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 Piwik Pro data can I load into DuckDB?

These are the Piwik Pro endpoints dlt can load into DuckDB:

How do I load only new Piwik Pro records?

Piwik Pro exposes offset on api/users/v2, 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": "users", "endpoint": {
    "path": "api/users/v2",
    "data_selector": "items",
    "incremental": {"cursor_path": "offset", "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 Piwik Pro pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading /api/analytics/v1/query/ and /api/analytics/v1/sessions/ from the Piwik Pro API into DuckDB:

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

@dlt.source
def piwik_pro_source(client_id=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://{account}.piwik.pro",
            "auth": {"type": "bearer", "token": client_id},
        },
        "resources": [
            {"name": "users", "endpoint": {"path": "api/users/v2", "data_selector": "items"}},
            {"name": "sessions", "endpoint": {"path": "api/analytics/v1/sessions/"}}
        ],
    }
    yield from rest_api_resources(config)


def load_piwik_pro_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="piwik_pro_pipeline",
        destination="duckdb",
        dataset_name="piwik_pro_data",
    )
    load_info = pipeline.run(piwik_pro_source())
    print(load_info)


if __name__ == "__main__":
    load_piwik_pro_to_duckdb()

Run it with python piwik_pro_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 Piwik Pro 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("piwik_pro_pipeline").dataset()
df = data.users.df()
print(df.head())

SQL:

Copy
SELECT * FROM piwik_pro_data.users LIMIT 10;

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

---

How do I deploy the Piwik Pro 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 Piwik Pro 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 Piwik Pro 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.
