Load Siteimprove data to Microsoft Fabric

Siteimprove is an enterprise platform for website governance, offering a REST API to access analytics, SEO, accessibility, and quality assurance data. Everything needed to build a working Siteimprove → Microsoft Fabric 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 Siteimprove to Microsoft Fabric pipeline

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

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 Siteimprove 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.

Siteimprove API at a glance

These values come from the Siteimprove API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Siteimprove API?

The API uses HTTP Basic Authentication. Clients must provide the API username and API key as the username and password, respectively.

1. Get your credentials

To obtain API credentials: 1. Log in to your Siteimprove platform account. 2. Navigate to Settings > Integrations > API > API Keys. 3. If the user does not exist, click 'Add user' and configure appropriate permissions. 4. Click 'Create API Key' and assign it to the user. 5. The resulting 'API username' and 'API key' are your credentials. The API uses Basic Access Authentication where the username is the API username and the password is the API key.

2. Add them to .dlt/secrets.toml

Copy
[sources.siteimprove_source]
api_username = "your_api_username_here"
api_key = "your_api_key_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 Siteimprove data can I load into Microsoft Fabric?

These are the Siteimprove endpoints dlt can load into Microsoft Fabric:

---

How do I load only new Siteimprove records?

The Siteimprove API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.

Copy
{"name": "sites", "endpoint": {
    "path": "sites",
    # Replace with a field that increases on every write.
    "incremental": {"cursor_path": "REPLACE_ME", "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 Siteimprove pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading /sites and /sites/{site_id}/accessibility/issues from the Siteimprove API into Microsoft Fabric:

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

@dlt.source
def siteimprove_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.siteimprove.com/v2",
            "auth": {"type": "http_basic", "username": "REPLACE_ME", "password": api_key},
        },
        "resources": [
            {"name": "sites", "endpoint": {"path": "sites", "data_selector": "items"}},
            {"name": "groups", "endpoint": {"path": "sites/{site_id}/groups", "data_selector": "items"}}
        ],
    }
    yield from rest_api_resources(config)


def load_siteimprove_to_fabric() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="siteimprove_pipeline",
        destination="fabric",
        dataset_name="siteimprove_data",
    )
    load_info = pipeline.run(siteimprove_source())
    print(load_info)


if __name__ == "__main__":
    load_siteimprove_to_fabric()

Run it with uv run python siteimprove_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 Siteimprove data in Microsoft Fabric?

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("siteimprove_pipeline").dataset()
df = data.sites.df()
print(df.head())

SQL:

Copy
SELECT * FROM siteimprove_data.sites LIMIT 10;

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

---

How do I deploy the Siteimprove to Microsoft Fabric 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 Siteimprove 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 Siteimprove 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.
