Square Python SDK Quickstart

Learn how to quickly set up and test the Square Python SDK.

Before you begin, you need a Square account and account credentials. You use the Square Sandbox for the Quickstart exercise.

1. Create a Square account and an application. For more information, see Create an Account and Application.

2. Get a Sandbox access token from the Developer Console. For more information, see Make your First API Call.

3. Install the following:

   • Python - Square supports Python version 3.7 and later.

   • Square Python SDK - To install it, use the pip command:

     pip install squareup

1. Open a new terminal window.

2. Create a new directory for your project and then go to that directory.

       mkdir quickstart
       cd ./quickstart

1. In your project directory, create a new file named quickstart.py with the following content:

   from square.http.auth.o_auth_2 import BearerAuthCredentials
   from square.client import Client
   import os
   
   client = Client(
       bearer_auth_credentials=BearerAuthCredentials(
           access_token=os.environ['SQUARE_ACCESS_TOKEN']
       ),
       environment='sandbox')
   
   result = client.locations.list_locations()
   
   if result.is_success():
       for location in result.body['locations']:
           print(f"{location['id']}: ", end="")
           print(f"{location['name']}, ", end="")
           print(f"{location['address']['address_line_1']}, ", end="")
           print(f"{location['address']['locality']}")
   
   elif result.is_error():
       for error in result.errors:
           print(error['category'])
           print(error['code'])
           print(error['detail'])

2. Save the quickstart.py file.

   This code does the following:

   • Creates a Client object using your Square access token. For more information, see Set your Square credentials.
   • Calls the list_locations method on the client object.
   • If the request is successful, the code prints the location information on the terminal.

The Python code in this Quickstart reads your Square Sandbox access token from the SQUARE_ACCESS_TOKEN environment variable. This helps avoid the use of hardcoded credentials in the code.

For the following commands, replace yourSandboxAccessToken with your Square Sandbox access token:

export SQUARE_ACCESS_TOKEN=yourSandboxAccessToken

Set-item -Path Env:SQUARE_ACCESS_TOKEN -Value yourSandboxAccessToken

set SQUARE_ACCESS_TOKEN=yourSandboxAccessToken

1. Run the following command:

   python ./quickstart.py

2. Verify the result. You should see at least one location (Square creates one location when you create a Square account).
