Python Data Loading from shopify 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 page provides technical documentation for using the open-source Python library, dlt, to load data from Shopify to Snowflake. Shopify is a comprehensive commerce platform that empowers anyone to initiate, expand, manage, and scale a business. On the other hand, Snowflake is a cloud-based data warehousing platform designed for storing, processing, and analyzing large data volumes. By utilizing dlt, you can effectively bridge these two platforms, transferring data from your Shopify store to the Snowflake warehouse for in-depth analysis and insights.

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 Shopify to Snowflake. You can run the following commands to create a starting point for loading data from Shopify to Snowflake:

# create a new directory
mkdir shopify_dlt_pipeline
cd shopify_dlt_pipeline
# initialize a new pipeline with your source and destination
dlt init shopify_dlt 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:


You now have the following folder structure in your project:

├── .dlt/
│ ├── config.toml # configs for your pipeline
│ └── secrets.toml # secrets for your pipeline
├── shopify_dlt/ # folder with source specific files
│ └── ...
├── # 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

log_level="WARNING" # the system log level of dlt
# use the dlthub_telemetry setting to enable/disable anonymous usage data reporting, see
dlthub_telemetry = true

shop_url = "shop_url" # please set me up!
organization_id = "organization_id" # please set me up!

generated secrets.toml

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

private_app_password = "private_app_password" # please set me up!
access_token = "access_token" # please set me up!

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 Shopify 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, as well as a folder shopify_dlt 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:

"""Pipeline to load shopify data into BigQuery.

import dlt
from dlt.common import pendulum
from typing import List, Tuple
from shopify_dlt import shopify_source, TAnyDateTime, shopify_partner_query

def load_all_resources(resources: List[str], start_date: TAnyDateTime) -> None:
"""Execute a pipeline that will load the given Shopify resources incrementally beginning at the given start date.
Subsequent runs will load only items updated since the previous run.

pipeline = dlt.pipeline(
pipeline_name="shopify", destination='snowflake', dataset_name="shopify_data"
load_info =

def incremental_load_with_backloading() -> None:
"""Load past orders from Shopify in chunks of 1 week each using the start_date and end_date parameters.
This can useful to reduce the potiential failure window when loading large amounts of historic data.
Chunks and incremental load can also be run in parallel to speed up the initial load.

pipeline = dlt.pipeline(
pipeline_name="shopify", destination='snowflake', dataset_name="shopify_data"

# Load all orders from 2023-01-01 to now
min_start_date = current_start_date = pendulum.datetime(2023, 1, 1)
max_end_date =

# Create a list of time ranges of 1 week each, we'll use this to load the data in chunks
ranges: List[Tuple[pendulum.DateTime, pendulum.DateTime]] = []
while current_start_date < max_end_date:
end_date = min(current_start_date.add(weeks=1), max_end_date)
ranges.append((current_start_date, end_date))
current_start_date = end_date

# Run the pipeline for each time range created above
for start_date, end_date in ranges:
print(f"Load orders between {start_date} and {end_date}")
# Create the source with start and end date set according to the current time range to filter
# created_at_min lets us set a cutoff to exclude orders created before the initial date of (2023-01-01)
# even if they were updated after that date
data = shopify_source(
start_date=start_date, end_date=end_date, created_at_min=min_start_date

load_info =

# Continue loading new data incrementally starting at the end of the last range
# created_at_min still filters out items created before 2023-01-01
load_info =
start_date=max_end_date, created_at_min=min_start_date

def load_partner_api_transactions() -> None:
"""Load transactions from the Shopify Partner API.
The partner API uses GraphQL and this example loads all transactions from the beginning paginated.

The `shopify_partner_query` resource can be used to run custom GraphQL queries to load paginated data.

pipeline = dlt.pipeline(

# Construct query to load transactions 100 per page, the `$after` variable is used to paginate
query = """query Transactions($after: String, first: 100) {
transactions(after: $after) {
edges {
node {

# Configure the resource with the query and json paths to extract the data and pagination cursor
resource = shopify_partner_query(
# JSON path pointing to the data item in the results
# JSON path pointing to the highest page cursor in the results
# The variable name used for pagination

load_info =

if __name__ == "__main__":
# Add your desired resources to the list...
resources = ["products", "orders", "customers"]
load_all_resources(resources, start_date="2000-01-01")

# incremental_load_with_backloading()

# load_partner_api_transactions()

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


4. Inspecting your load result

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

dlt pipeline shopify 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 shopify 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:
