FlightLogger Python API Docs | dltHub

FlightLogger is a flight training management platform that provides a GraphQL API for custom integrations and data access. The REST API base URL is https://api.flightlogger.net/graphql and all requests require an 'Authorization' header containing a Bearer token.

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 add "dlt[hub]" and start loading FlightLogger data in under 10 minutes.

What data can I load from FlightLogger?

Here are some of the endpoints you can load from FlightLogger:

---

How do I authenticate with the FlightLogger API?

The API uses Bearer token authentication. Requests must include the 'Authorization' header with the value 'Bearer <YOUR_API_TOKEN>'.

1. Get your credentials

To obtain your API credentials, log in to your FlightLogger account and navigate to the API section within the Help Center (accessible via your user account settings). From there, you can generate a personal API token, which is used for Bearer authentication. Ensure you have the appropriate user role permissions to access the data you intend to retrieve.

2. Add them to .dlt/secrets.toml

Copy
[sources.flightlogger_source]
access_token = "your_api_token_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 init
uv add "dlt[hub]"

1. Install the dlt AI harness:

Copy
uv run dlthub 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
uv run dlthub ai toolkit install rest-api-pipeline

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 FlightLogger 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
uv run python flightlogger_pipeline.py

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

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

Inspect your pipeline and data:

Copy
uv run dlthub 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 user and flights (Note: The FlightLogger API is a GraphQL API accessed via a single endpoint, https://api.flightlogger.net/graphql, where resources are queried as fields.) from the FlightLogger 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 flightlogger_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.flightlogger.net/graphql",
            "auth": {"type": "bearer", "token": access_token},
        },
        "resources": [
            {"name": "bookings", "endpoint": {"path": "graphql"}},
            {"name": "accounting_transactions", "endpoint": {"path": "graphql"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="flightlogger_pipeline",
        destination="duckdb",
        dataset_name="flightlogger_data",
    )
    load_info = pipeline.run(flightlogger_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("flightlogger_pipeline").dataset()
sessions_df = data.bookings.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM flightlogger_data.bookings LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("flightlogger_pipeline").dataset()
data.bookings.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 FlightLogger 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.
