Load Wolt data to DuckDB

Wolt for Developers provides access to marketplace and logistics APIs for integrating POS, menu management, and delivery services directly into the Wolt platform. Everything needed to build a working Wolt → 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 Wolt 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 Wolt 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 Wolt 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.

Wolt API at a glance

These values come from the Wolt API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Wolt API?

Wolt APIs primarily use Bearer tokens for authentication, which should be included in the Authorization header (e.g., 'Authorization: Bearer '). Some services like the Wolt Drive API may also refer to this token as a 'merchant key'.

1. Get your credentials

Wolt API credentials (referred to as a Merchant Key or Bearer token) are not generated via a self-service dashboard. To obtain your token, you must contact your local Wolt Drive representative, technical account manager, or Wolt contact person. They will provide staging credentials for your development phase and production credentials once you have successfully completed testing.

2. Add them to .dlt/secrets.toml

Copy
[sources.wolt_source]
token = "your_wolt_token_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 Wolt data can I load into DuckDB?

These are the Wolt endpoints dlt can load into DuckDB:

---

How do I load only new Wolt records?

The Wolt 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": "delivery_areas", "endpoint": {
    "path": "merchants/{merchant_id}/delivery-areas",
    # 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 Wolt pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading /merchants/{merchant_id}/delivery-areas and /order/{wolt_order_reference_id}/handshake-delivery from the Wolt API into DuckDB:

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

@dlt.source
def wolt_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://daas-public-api.wolt.com",
            "auth": {"type": "bearer", "token": access_token},
        },
        "resources": [
            {"name": "delivery_areas", "endpoint": {"path": "merchants/{merchant_id}/delivery-areas"}},
            {"name": "shipment_promises", "endpoint": {"path": "venues/{venue_id}/shipment-promises"}}
        ],
    }
    yield from rest_api_resources(config)


def load_wolt_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="wolt_pipeline",
        destination="duckdb",
        dataset_name="wolt_data",
    )
    load_info = pipeline.run(wolt_source())
    print(load_info)


if __name__ == "__main__":
    load_wolt_to_duckdb()

Run it with python wolt_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 Wolt 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("wolt_pipeline").dataset()
df = data.delivery_areas.df()
print(df.head())

SQL:

Copy
SELECT * FROM wolt_data.delivery_areas LIMIT 10;

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

---

How do I deploy the Wolt 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 Wolt 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 Wolt 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.
