To connect to BigCommerce, you can use either a DSN or an ODBC connection string. Both of these methods use the connect function.

Connect to a DSN

To connect using a DSN:

cnxn = pyodbc.connect("DSN=CData BigCommerce Sys;User=MyUser;Password=MyPassword")

Provide a Driver Connection String

To connect using an ODBC connection string:

cnxn = pyodbc.connect("DRIVER={CData ODBC Driver for BigCommerce};AuthScheme=OAuth;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;StoreId='YoUrSToREId';CallbackURL='http://localhost:33333'")
