Load Velo Payments data in Python using dltHub

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

In this guide, we'll set up a complete Velo Payments 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 velo_payments_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.payouts.velopayments.com/v3/",
            "auth": {
                "type": "bearer",
                "token": access_token,
            },
        },
        "resources": [
            payees, payouts
        ],
    }
    [...]
    yield from rest_api_resources(config)


def get_data() -> None:
    # Connect to destination
    pipeline = dlt.pipeline(
        pipeline_name='velo_payments_pipeline',
        destination='duckdb',
        dataset_name='velo_payments_data', 
    )
    # Load the data
    load_info = pipeline.run(velo_payments_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 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 velo_payments’s API and loads it into Iceberg, DataFrames, files, or a database of your choice. Here are some of the endpoints you can load:

  • Users Management: Create, retrieve, update, and delete user accounts; manage user authentication and MFA settings
  • Payees Management: Manage payee information and delete payee records
  • Payouts: Create, retrieve, and delete payout transactions
  • MFA (Multi-Factor Authentication): Register and unregister MFA for user accounts

You will then debug the Velo Payments 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:

Now you're ready to get started!

  1. ⚙️ Set up dlt Workspace

    Install dlt with duckdb support:

    pip install dlt[workspace]

    Initialize a dlt pipeline with Velo Payments support.

    dlt init dlthub:velo_payments duckdb

    The init command will setup the necessary files and folders for the next step.

  2. 🤠 Start LLM-assisted coding

    Here’s a prompt to get you started:

    Prompt
    Please generate a REST API Source for Velo Payments API, as specified in @velo_payments-docs.yaml 
Start with endpoint(s) payees and payouts and skip incremental loading for now. 
Place the code in velo_payments_pipeline.py and name the pipeline velo_payments_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 velo_payments_pipeline.py and await further instructions.

  3. 🔒 Set up credentials

    Authentication uses Bearer tokens passed in the Authorization header. Include the header Authorization: Bearer <token> where the token is a UUID-format access token provided by Velo Payments.

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

  4. 🏃‍♀️ Run the pipeline in the Python terminal in Cursor

    python velo_payments_pipeline.py

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

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

  5. 📈 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 velo_payments_pipeline show

  6. 🐍 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("velo_payments_pipeline").dataset()
# get payees table as Pandas frame
data.payees.df().head()
