Posit Connect Python API Docs | dltHub

Posit Connect's OAuth integrations allow secure access to short-lived tokens. The Connect API enables remote user actions. OAuth integrations can be managed via the Connect UI. The REST API base URL is https://<connect_host>/__api__ and All requests require an API key sent in the Authorization header with the prefix "Key ".

dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv pip install "dlt[workspace]" and start loading Posit Connect data in under 10 minutes.

What data can I load from Posit Connect?

Here are some of the endpoints you can load from Posit Connect:

---

How do I authenticate with the Posit Connect API?

Posit Connect uses API keys for the Server API. Provide Authorization: Key <CONNECT_API_KEY> on each request.

1. Get your credentials

1. As a Posit Connect administrator open the Admin UI.
2. Go to System → Integrations and create or enable a Connect API integration (optional: set max_role).
3. Create an API key (System → API Keys or programmatic provisioning) or obtain an ephemeral visitor API key via credential exchange from content.
4. Use the API key in the Authorization header with the literal prefix "Key " (space required).

2. Add them to .dlt/secrets.toml

Copy
[sources.posit_connect_source]
api_key = "your_api_key_here"

dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.

How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

Copy
uv venv && source .venv/bin/activate
uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

Copy
dlt ai init --agent <your-agent> # <agent>: claude | cursor | codex

This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →

2. Install the rest-api-pipeline toolkit:

Copy
dlt ai toolkit rest-api-pipeline install

This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →

3. Start LLM-assisted coding:

Use /find-source to load data from the Posit Connect API into DuckDB.

The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.

4. Run the pipeline:

Copy
python posit_connect_pipeline.py

If everything is configured correctly, you'll see output like this:

Copy
Pipeline posit_connect_pipeline load step completed in 0.26 seconds
1 load package(s) were loaded to destination duckdb and into dataset posit_connect_data
The duckdb destination used duckdb:/posit_connect.duckdb location to store data
Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

Copy
dlt pipeline posit_connect_pipeline show

This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.

Python pipeline example

This example loads oauth_integrations and content from the Posit Connect API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

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

@dlt.source
def posit_connect_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://<connect_host>/__api__",
            "auth": {
                "type": "api_key",
                "api_key": api_key,
            },
        },
        "resources": [
            {"name": "oauth_integrations", "endpoint": {"path": "__api__/v1/oauth/integrations"}},
            {"name": "content", "endpoint": {"path": "__api__/v1/content"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="posit_connect_pipeline",
        destination="duckdb",
        dataset_name="posit_connect_data",
    )
    load_info = pipeline.run(posit_connect_source())
    print(load_info)

To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.

---

How do I query the loaded data?

Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("posit_connect_pipeline").dataset()
sessions_df = data.content.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM posit_connect_data.content LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("posit_connect_pipeline").dataset()
data.content.df().head()

See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.

---

What destinations can I load Posit Connect data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
