SendOwl Python API Docs | dltHub

SendOwl is a digital product ecommerce platform that provides a REST API to manage products, orders, customers and related ecommerce resources. The REST API base URL is https://api.sendowl.com/api/v1 and all requests require HTTP Basic authentication (API key and secret).

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 SendOwl data in under 10 minutes.

What data can I load from SendOwl?

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

---

How do I authenticate with the SendOwl API?

API requests must use HTTP Basic Auth with your API key as the username and API secret as the password. Requests should be sent over HTTPS.

1. Get your credentials

1. Log in to your SendOwl dashboard. 2) Navigate to Settings → Advanced → API. 3) Enable the API if it is not already enabled. 4) Copy the displayed API Key and API Secret. 5) Store them securely; they will be used as the username and password for HTTP Basic Auth.

2. Add them to .dlt/secrets.toml

Copy
[sources.sendowl_source]
api_key = "YOUR_SENDOWL_API_KEY"
api_secret = "YOUR_SENDOWL_API_SECRET"

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 SendOwl 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 sendowl_pipeline.py

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

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

Inspect your pipeline and data:

Copy
dlt pipeline sendowl_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 products and orders from the SendOwl 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 sendowl_source(api_key, api_secret=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.sendowl.com/api/v1",
            "auth": {
                "type": "http_basic",
                "api_key": api_key, api_secret,
            },
        },
        "resources": [
            {"name": "products", "endpoint": {"path": "products"}},
            {"name": "orders", "endpoint": {"path": "orders"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="sendowl_pipeline",
        destination="duckdb",
        dataset_name="sendowl_data",
    )
    load_info = pipeline.run(sendowl_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("sendowl_pipeline").dataset()
sessions_df = data.products.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM sendowl_data.products LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("sendowl_pipeline").dataset()
data.products.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 SendOwl 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.

Troubleshooting

Authentication failures

If you receive 401 or 403 responses, verify you are using HTTP Basic Auth with the API key (username) and API secret (password). Ensure the API is enabled in Settings → Advanced → API and you are using HTTPS.

Rate limiting and call rate

Do not call the API more than once per second; abusive call rates can lead to IP blacklisting. For higher throughput contact SendOwl support.

Pagination quirks

Index endpoints are paginated. Default page=1 and per_page=10; maximum per_page=50. Use page and per_page query parameters to iterate through results.

Validation and common API errors

Validation errors return HTTP 422 with details in the response. Ensure required fields are provided and follow the formats described in the resource documentation.

Ensure that the API key is valid to avoid 401 Unauthorized errors. Also, verify endpoint paths and parameters to avoid 404 Not Found errors.
