Snowflake does not provide a public REST API to directly access or manage the data stored in it. Instead, Snowflake provides a Python connector that you can use to interact with your Snowflake account, execute SQL queries, and fetch data.
Step-by-step guide on how to access Snowflake data using the Python connector
Install the Snowflake Connector for Python. You can install the Snowflake Connector for Python via pip:
Connect to Snowflake. Use your Snowflake credentials to establish a connection to your Snowflake account.
Execute SQL Queries. Use the connection object to execute SQL queries on your Snowflake account.
Fetch Data. Fetch the data returned by the query and store it in a pandas DataFrame for easier manipulation.
Below is an example Python script that demonstrates these steps:
Replace the placeholder values in the conn object and the cur.execute method with your own Snowflake account details and the SQL query that you want to execute.
Note that this is a general approach and the exact details may vary based on your specific use case and Snowflake configuration. Additionally, you may need to install additional packages, such as pandas, if you have not already installed them.
Why get data from Snowflake Rest API using Python?
Sometimes, it's just easier
The Snowflake Python connector is specifically designed to interact with Snowflake using Python. It provides a simple and intuitive interface to connect to your Snowflake account, execute SQL queries, and fetch data.
Perf can be a big deal
The Snowflake Python connector is optimized for performance. It handles the low-level details of the connection, query execution, and data retrieval, which can lead to better performance compared to using a generic database connector or a third-party API.
Security is the priority
The Snowflake Python connector uses secure methods to authenticate and interact with your Snowflake account. This includes support for multi-factor authentication (MFA), client-side encryption, and other security features.
Again, sometimes, for some use cases it just is more convenient & flexible
Using the Snowflake Python connector gives you the flexibility to execute any SQL query on your Snowflake account and fetch the results. This can be more flexible than using a third-party API, which may have limitations on the types of queries that can be executed or the amount of data that can be retrieved.
Any risks associated with using the Snowflake Python connector?
Security can be at risk
Even though the Snowflake Python connector provides secure methods to interact with your Snowflake account, there is always a risk associated with sending your credentials and data over the internet. It is important to follow best practices for securing your Snowflake account and your Python code to minimize this risk.
It consumes more credits?
Executing SQL queries and fetching data from Snowflake consumes resources, both on your local machine and on the Snowflake servers. It is important to be mindful of the resource usage and costs associated with your queries.
Data Transfer inefficiencies
Fetching large amounts of data from Snowflake can result in large data transfers over the internet. This can impact the performance of your application and may incur additional costs for data transfer.
Using the Snowflake Python connector introduces a dependency on the Snowflake service and the Snowflake Python connector package. This means that your application may be affected by any changes or outages in the Snowflake service or the Snowflake Python connector package.

Fantastic tool for data discovery and documentation
“[I like] The easy to use interface and the speed of finding the relevant assets that you're looking for in your database. I also really enjoy the score given to each table, [which] lets you prioritize the results of your queries by how often certain data is used.”
