Migrate to the Square Python SDK

Follow the instructions below to migrate your apps from the deprecated squareconnect library to the new square library.

Install the new library

Install the latest Square Python SDK using pip:

pip install squareup

Update your code

1. Change all instances of import 'squareconnect' to import 'square'.
2. Replace models with plain Python dictionary equivalents.
3. Update client instantiation to follow the method outlined below.
4. Update code for accessing response data to follow the method outlined below.
5. Check response.is_success or response.is_error rather than rescuing exceptions for flow control.

To simplify your code, we also recommend that you use method chaining to access APIs instead of explicitly instantiating multiple clients.

Client instantiation

from square.client import Client

square = Client(access_token='YOUR ACCESS TOKEN')

response = square.API.ENDPOINT(body=BODY)

Accessing response data

if response.is_success():
  print({response.body})
elif response.is_error():
  print({response.errors})

An example code migration

As a specific example, consider the following code for creating a new customer from this dictionary:

new_customer = {
  'given_name': 'Ava',
  'address': {
    'address_line_1': '555 Electric Ave',
    'locality': 'Los Angeles',
    'country': 'US'
  }
}

With the deprecated squareconnect library, this is how you instantiate a client for the Customers API, format the request, and call the endpoint:

from squareconnect import ApiClient
from squareconnect.rest import ApiException
from squareconnect.apis.customers_api import CustomersApi
from squareconnect.models.create_customer_request import CreateCustomerRequest

# Instantiate and initialize the client
api_client = ApiClient()
api_client.configuration.access_token = 'YOUR ACCESS TOKEN'

# Get an instance of the Square API you want call
api_instance = CustomersApi(api_client)

# Build the request
create_customer_request = CreateCustomerRequest(
  given_name=new_customer['given_name'],
  address=new_customer['address'],
)

# Call create_customer method to create a new customer and handle the response
try:
  api_response = api_instance.create_customer(create_customer_request)
  print(f"Success: {api_response.customer}")
except ApiException as err:
  print(f"Exception when calling CustomersApi->create_customer: {err}")

Now consider equivalent code using the new square library:

from square.client import Client

# Instantiate the client
client = Client(access_token='YOUR ACCESS TOKEN')

# Call create_customer method to create a new customer
result = client.customers.create_customer(new_customer)

# Handle the result
if result.is_success():
  # Display the response as text
  print(f"Success: {result.text}")
# Call the error method to see if the call failed
elif result.is_error():
  print(f"Errors: {result.errors}")

That's it! What was once a multi-block process can be handled in 2 lines of code and an if/elif block. Migrating to the square library reduces boilerplate and lets you can focus on the parts of your code that really matter.
