Unleashed Python API Docs | dltHub

Build a Unleashed-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.

Last updated:

Unleashed Software is a cloud-based inventory management platform that offers a REST API for accessing business data including sales orders, products, and customers. The REST API base URL is https://api.unleashedsoftware.com and requests require five specific headers including an API ID and a HMAC-SHA256 signature.

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 Unleashed data in under 10 minutes.


What data can I load from Unleashed?

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

ResourceEndpointMethodData selectorDescription
productsProductsGETProductsList products with pagination support
sales_ordersSalesOrdersGETSalesOrdersList sales orders with pagination support
sales_shipmentsSalesShipmentsGETSalesShipmentsList sales shipments with pagination support
customersCustomersGETCustomersList customers with pagination support
suppliersSuppliersGETSuppliersList suppliers with pagination support

How do I authenticate with the Unleashed API?

Authentication requires providing API ID and a request signature via HTTP headers. The signature must be generated as an HMAC-SHA256 hash of the query string using the API key as the secret. Required headers include Content-Type, Accept, api-auth-id, api-auth-signature, and client-type.

1. Get your credentials

To obtain your API credentials, log in to your Unleashed account as the Account Owner. Navigate to the 'Integration' menu and select 'Unleashed API Access'. Your unique API ID and API Key will be displayed here for viewing and copying. Note that these credentials are unique to each account and cannot be changed or refreshed.

2. Add them to .dlt/secrets.toml

[sources.unleashed_source] api_id = "your_api_id_here" 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:

uv init uv add "dlt[hub]"

1. Install the dlt AI harness:

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:

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 Unleashed 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:

uv run python unleashed_pipeline.py

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

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

Inspect your pipeline and data:

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 /Products and /Invoices from the Unleashed API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def unleashed_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.unleashedsoftware.com", "auth": {"type": "api_key", "api_key": api_key}, }, "resources": [ {"name": "products", "endpoint": {"path": "Products", "data_selector": "Products"}}, {"name": "sales_orders", "endpoint": {"path": "SalesOrders", "data_selector": "SalesOrders"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="unleashed_pipeline", destination="duckdb", dataset_name="unleashed_data", ) load_info = pipeline.run(unleashed_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):

import dlt data = dlt.pipeline("unleashed_pipeline").dataset() sessions_df = data.sales_orders.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM unleashed_data.sales_orders LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("unleashed_pipeline").dataset() data.sales_orders.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 Unleashed data to?

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

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

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