Load Katana MRP data in Python using dltHub

Build a Katana MRP-to-database or-dataframe pipeline in Python using dlt with automatic Cursor support.

In this guide, we'll set up a complete Katana MRP data pipeline from API credentials to your first data load in just 10 minutes. You'll end up with a fully declarative Python pipeline based on dlt's REST API connector, like in the partial example code below:

Example code
@dlt.source
def katana_mrp_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.katanamrp.com/v",
            "auth": {
                "type": "bearer",
                "token": access_token,
            },
        },
        "resources": [
            "customers",
            "shipping_fee",
            "costs"
            ],
    }
    [...]
    yield from rest_api_resources(config)


def get_data() -> None:
    # Connect to destination
    pipeline = dlt.pipeline(
        pipeline_name='katana_mrp_pipeline',
        destination='duckdb',
        dataset_name='katana_mrp_data', 
    )
    # Load the data
    load_info = pipeline.run(katana_mrp_source())
    print(load_info)

Why use dltHub Workspace with LLM Context to generate Python pipelines?

Accelerate pipeline development with AI-native context
Debug pipelines, validate schemas and data with the integrated Pipeline Dashboard
Build Python notebooks for end users of your data
Low maintenance thanks to Schema evolution with type inference, resilience and self documenting REST API connectors. A shallow learning curve makes the pipeline easy to extend by any team member
dlt is the tool of choice for Pythonic Iceberg Lakehouses, bringing mature data loading loading to pythonic Iceberg with or without catalogs

What you’ll do

We’ll show you how to generate a readable and easily maintainable Python script that fetches data from katana_mrp’s API and loads it into Iceberg, DataFrames, files, or a database of your choice. Here are some of the endpoints you can load:

Customers: Retrieve customer information and manage customer data.
Shipping Fee: Fetch shipping fee details for specific orders.
Costs: Get cost information for specific products.
Products: Access product details and filter by category.
Sales Orders: Manage and retrieve sales order information.

You will then debug the Katana MRP pipeline using our Pipeline Dashboard tool to ensure it is copying the data correctly, before building a Notebook to explore your data and build reports.

Setup & steps to follow

💡
Before getting started, let's make sure Cursor is set up correctly:

We suggest using a model like Claude 3.7 Sonnet or better
Index the REST API Source tutorial: https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api/ and add it to context as @dlt rest api
Read our full steps on setting up Cursor

Now you're ready to get started!

⚙️ Set up dlt Workspace

Install dlt with duckdb support:
```
pip install dlt[workspace]
```
Initialize a dlt pipeline with Katana MRP support.
```
dlt init dlthub:katana_mrp duckdb
```
The init command will setup the necessary files and folders for the next step.

🤠 Start LLM-assisted coding

Here’s a prompt to get you started:

Prompt
Please generate a REST API Source for Katana MRP API, as specified in @katana_mrp-docs.yaml 
Start with endpoints "customers" and "shipping_fee" and skip incremental loading for now. 
Place the code in katana_mrp_pipeline.py and name the pipeline katana_mrp_pipeline. 
If the file exists, use it as a starting point. 
Do not add or modify any other files. 
Use @dlt rest api as a tutorial. 
After adding the endpoints, allow the user to run the pipeline with python katana_mrp_pipeline.py and await further instructions.

🔒 Set up credentials

Authentication is managed via OAuth 2.0, requiring an access token that must be obtained prior to making requests.

To get the appropriate API keys, please visit the original source at https://www.katanamrp.com/. If you want to protect your environment secrets in a production environment, look into setting up credentials with dlt.

🏃‍♀️ Run the pipeline in the Python terminal in Cursor


python katana_mrp_pipeline.py

If your pipeline runs correctly, you’ll see something like the following:


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

📈 Debug your pipeline and data with the Pipeline Dashboard

Now that you have a running pipeline, you need to make sure it’s correct, so you do not introduce silent failures like misconfigured pagination or incremental loading errors. By launching the dlt Workspace Pipeline Dashboard, you can see various information about the pipeline to enable you to test it. Here you can see:
- Pipeline overview: State, load metrics
- Data’s schema: tables, columns, types, hints
- You can query the data itself
```
dlt pipeline katana_mrp_pipeline show --dashboard
```
🐍 Build a Notebook with data explorations and reports

With the pipeline and data partially validated, you can continue with custom data explorations and reports. To get started, paste the snippet below into a new marimo Notebook and ask your LLM to go from there. Jupyter Notebooks and regular Python scripts are supported as well.
```
import dlt

data = dlt.pipeline("katana_mrp_pipeline").dataset()
# get "customers" table as Pandas frame
data.customers.df().head()
```

Running into errors?

Be aware of rate limits that may apply; ensure to check the API documentation for specifics. Handle 401 Unauthorized errors by validating the access token. For large datasets, utilize pagination with 'page' and 'limit' parameters.
