Python Guide: Loading Stripe Data to Snowflake using dlt Library

Need help deploying these pipelines, or figuring out how to run them in your data stack?

Join our Slack community or book a call with our support engineer Violetta.

This technical documentation provides guidelines on using the open-source Python library, dlt, to load data from Stripe to Snowflake. Stripe is a comprehensive payments platform that supports 135+ currencies, offering simple APIs, easy integration, and transparent pricing. Snowflake, on the other hand, is a cloud-based data warehousing platform designed for storing, processing, and analyzing large volumes of data. By utilizing dlt, you can conveniently transfer data from Stripe to Snowflake, leveraging the robust features of both platforms. For more details about Stripe, visit https://stripe.com.

dlt Key Features​

  • Snowflake Integration: dlt provides seamless integration with Snowflake, supporting various authentication methods including password, key pair, and external authentication. The installation process is straightforward with the command pip install dlt[snowflake]. Learn more
  • Stripe API: dlt includes a verified source for Stripe API, allowing businesses to securely process and manage customer transactions. It supports data extraction from multiple endpoints, including Subscription, Account, Coupon, Customer, Product, Price, Event, Invoice, and BalanceTransaction. Learn more
  • Data Lineage: dlt supports data lineage, which is crucial for understanding the lifecycle of data and its movement across systems. It helps in maintaining the integrity and consistency of data. Learn more
  • Governance Support: dlt pipelines offer robust governance support through key mechanisms such as pipeline metadata utilization, schema enforcement and curation, and schema change alerts. These contribute to better data management practices, compliance adherence, and overall data governance. Learn more
  • Data Extraction: dlt makes data extraction simple and scalable through the use of decorators for data-producing functions, iterators, chunking, and parallelization. It also utilizes implicit extraction Directed Acyclic Graphs (DAGs) for efficient API calls for data enrichments or transformations. Learn more

Getting started with your pipeline locally​

0. Prerequisites​

dlt requires Python 3.8 or higher. Additionally, you need to have the pip package manager installed, and we recommend using a virtual environment to manage your dependencies. You can learn more about preparing your computer for dlt in our installation reference.

1. Install dlt​

First you need to install the dlt library with the correct extras for Snowflake:

pip install "dlt[snowflake]"

The dlt cli has a useful command to get you started with any combination of source and destination. For this example, we want to load data from Stripe to Snowflake. You can run the following commands to create a starting point for loading data from Stripe to Snowflake:

# create a new directory
mkdir stripe_analytics_pipeline
cd stripe_analytics_pipeline
# initialize a new pipeline with your source and destination
dlt init stripe_analytics snowflake
# install the required dependencies
pip install -r requirements.txt

The last command will install the required dependencies for your pipeline. The dependencies are listed in the requirements.txt:


pandas>=2.0.0
stripe>=5.0.0
dlt[snowflake]>=0.3.5

You now have the following folder structure in your project:

stripe_analytics_pipeline/
├── .dlt/
│   ├── config.toml          # configs for your pipeline
│   └── secrets.toml         # secrets for your pipeline
├── stripe_analytics/                   # folder with source specific files
│   └── ...
├── stripe_analytics_pipeline.py        # your main pipeline script
├── requirements.txt         # dependencies for your pipeline
└── .gitignore               # ignore files for git (not required)

2. Configuring your source and destination credentials​

The dlt cli will have created a .dlt directory in your project folder. This directory contains a config.toml file and a secrets.toml file that you can use to configure your pipeline. The automatically created version of these files look like this:

generated config.toml​

# put your configuration values here

[runtime]
log_level="WARNING"  # the system log level of dlt
# use the dlthub_telemetry setting to enable/disable anonymous usage data reporting, see https://dlthub.com/docs/telemetry
dlthub_telemetry = true

generated secrets.toml​

# put your secret values and credentials here. do not share this file and do not push it to github

[sources.stripe_analytics]
stripe_secret_key = "stripe_secret_key" # please set me up!

[destination.snowflake.credentials]
database = "database" # please set me up!
password = "password" # please set me up!
username = "username" # please set me up!
host = "host" # please set me up!
warehouse = "warehouse" # please set me up!
role = "role" # please set me up!

2.1. Adjust the generated code to your usecase​

Further help setting up your source and destinations
  • Read more about setting up the Stripe source in our docs.
  • Read more about setting up the Snowflake destination in our docs.

3. Running your pipeline for the first time​

The dlt cli has also created a main pipeline script for you at stripe_analytics_pipeline.py, as well as a folder stripe_analytics that contains additional python files for your source. These files are your local copies which you can modify to fit your needs. In some cases you may find that you only need to do small changes to your pipelines or add some configurations, in other cases these files can serve as a working starting point for your code, but will need to be adjusted to do what you need them to do.

The main pipeline script will look something like this:


from typing import Optional, Tuple

import dlt
from pendulum import DateTime, datetime
from stripe_analytics import (
    ENDPOINTS,
    INCREMENTAL_ENDPOINTS,
    incremental_stripe_source,
    metrics_resource,
    stripe_source,
)


def load_data(
    endpoints: Tuple[str, ...] = ENDPOINTS + INCREMENTAL_ENDPOINTS,
    start_date: Optional[DateTime] = None,
    end_date: Optional[DateTime] = None,
) -> None:
    """
    This demo script uses the resources with non-incremental
    loading based on "replace" mode to load all data from provided endpoints.

    Args:
        endpoints: A tuple of endpoint names to retrieve data from. Defaults to most popular Stripe API endpoints.
        start_date: An optional start date to limit the data retrieved. Defaults to None.
        end_date: An optional end date to limit the data retrieved. Defaults to None.
    """
    pipeline = dlt.pipeline(
        pipeline_name="stripe_analytics",

    source = stripe_source(
        endpoints=endpoints, start_date=start_date, end_date=end_date

    print(load_info)

if __name__ == "__main__":
    # load only data that was created during the period between the Jan 1, 2024 (incl.), and the Feb 1, 2024 (not incl.).
    load_data(start_date=datetime(2024, 1, 1), end_date=datetime(2024, 2, 1))
    # load only data that was created during the period between the May 3, 2023 (incl.), and the March 1, 2024 (not incl.).
    load_incremental_endpoints(
        endpoints=("Event",),
        initial_start_date=datetime(2023, 5, 3),

    )
    # load Subscription and Event data, calculate metrics, store them in a database
    load_data_and_get_metrics()

Provided you have set up your credentials, you can run your pipeline like a regular python script with the following command:

python stripe_analytics_pipeline.py

4. Inspecting your load result​

You can now inspect the state of your pipeline with the dlt cli:

dlt pipeline stripe_analytics info

You can also use streamlit to inspect the contents of your Snowflake destination for this:

# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline stripe_analytics show

5. Next steps to get your pipeline running in production​

One of the beauties of dlt is, that we are just a plain Python library, so you can run your pipeline in any environment that supports Python >= 3.8. We have a couple of helpers and guides in our docs to get you there:
