BQE CORE Python API Docs | dltHub

BQE CORE is a business management and accounting platform that provides REST APIs for managing company data including time entries, CRM, and HR modules. The REST API base URL is https://[dynamic-data-center-host] (retrieved from token response) and all requests require a Bearer token in the Authorization header.

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 BQE CORE data in under 10 minutes.

What data can I load from BQE CORE?

Here are some of the endpoints you can load from BQE CORE:

---

How do I authenticate with the BQE CORE API?

All requests require an 'Authorization: Bearer [YOUR_ACCESS_TOKEN]' header where the access token is obtained via an OAuth 2.0 flow. The base URL is dynamic and must be retrieved from the 'endpoint' field in the successful token response.

1. Get your credentials

1. Register for a developer account at the BQE CORE Developer Portal (https://api-developer.bqecore.com/webapp). 2. Once logged in, navigate to the Dashboard. 3. Add your application to the account. 4. Upon adding the app, BQE CORE will generate OAuth client credentials, specifically a Client ID and a Client Secret. 5. Copy the Client Secret immediately and store it securely, as it will not be displayed again. These credentials are required for the OAuth 2.0 authorization flow to obtain access tokens.

2. Add them to .dlt/secrets.toml

Copy
[sources.bqe_core_source]
access_token = "REPLACE_ME"

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 harness:

Copy
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
dlthub 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 BQE CORE 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 bqe_core_pipeline.py

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

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

Inspect your pipeline and data:

Copy
dlt pipeline bqe_core_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 token and authorize from the BQE CORE 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 bqe_core_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://[dynamic-data-center-host] (retrieved from token response)",
            "auth": {"type": "bearer", "token": access_token},
        },
        "resources": [
            {"name": "bill", "endpoint": {"path": "bill"}},
            {"name": "invoice", "endpoint": {"path": "invoice"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="bqe_core_pipeline",
        destination="duckdb",
        dataset_name="bqe_core_data",
    )
    load_info = pipeline.run(bqe_core_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("bqe_core_pipeline").dataset()
sessions_df = data.bill.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM bqe_core_data.bill LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("bqe_core_pipeline").dataset()
data.bill.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 BQE CORE 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.
