Load Canny data to DuckDB

Build a Canny to DuckDB pipeline with your coding agent. One prompt scaffolds it with the dltHub AI harness, plus the Canny API base URL, auth, endpoints, and incremental loading.

Canny is a customer feedback and product management platform that provides a REST API to manage boards, posts, comments, votes, users, and companies. Everything needed to build a working Canny → 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 Canny to DuckDB pipeline

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

Prompt
Run uvx dlthub-init@latest to build a pipeline from Canny 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 Canny 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.


Canny API at a glance

Base URLhttps://canny.io/api/v1
Example endpointPOST posts/list
Authenticationall requests require a secret API key provided via request body parameter or header — sent in the x-api-key header
PaginationCursor-based via cursor, page size via limit. The API supports two pagination methods: cursor-based (using the 'cursor' parameter) and skip-based (using the 'skip' parameter). Both use 'limit' to control the page size.
API referencehttps://developers.canny.io/api-reference

These values come from the Canny API reference — the authoritative source if anything here looks out of date.


How do I authenticate with the Canny API?

Authentication is performed by including your secret API key either as a POST parameter named 'apiKey' or as an HTTP header named 'x-api-key'.

1. Get your credentials

To obtain your Canny API credentials, follow these steps: 1. Log in to your Canny account with administrator access. 2. Navigate to your Company Settings. 3. Locate the API section (often labeled 'API Keys' or 'API'). 4. Generate a new secret key or copy the existing one displayed in the dashboard. Store this key securely as it provides full access to your workspace data.

2. Add them to .dlt/secrets.toml

[sources.canny_source] api_key = "your_canny_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 Canny data can I load into DuckDB?

These are the Canny endpoints dlt can load into DuckDB:

ResourceEndpointMethodData selectorDescription
boardsboards/listPOSTList all boards for the company
postsposts/listPOSTList all posts, optionally filtered
commentscomments/listPOSTList comments, optionally filtered
usersusers/listPOSTList all users
tagstags/listPOSTList all tags for a board

How do I load only new Canny records?

The Canny 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.

{"name": "posts", "endpoint": { "path": "posts/list", # 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 Canny pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading boards and posts from the Canny API into DuckDB:

import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def canny_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://canny.io/api/v1", "auth": {"type": "api_key", "api_key": api_key, "name": "x-api-key", "location": "header"}, }, "resources": [ {"name": "posts", "endpoint": {"path": "posts/list"}}, {"name": "comments", "endpoint": {"path": "comments/list"}} ], } yield from rest_api_resources(config) def load_canny_to_duckdb() -> None: pipeline = dlt.pipeline( pipeline_name="canny_pipeline", destination="duckdb", dataset_name="canny_data", ) load_info = pipeline.run(canny_source()) print(load_info) if __name__ == "__main__": load_canny_to_duckdb()

Run it with python canny_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 Canny 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):

import dlt data = dlt.pipeline("canny_pipeline").dataset() df = data.posts.df() print(df.head())

SQL:

SELECT * FROM canny_data.posts LIMIT 10;

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


How do I deploy the Canny 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 Canny 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 Canny data to?

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

DestinationExample value
PostgreSQL"postgres"
BigQuery"bigquery"
Snowflake"snowflake"
Redshift"redshift"
Databricks"databricks"
Filesystem (S3, GCS, Azure)"filesystem"

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.
