To connect to ServiceNow, 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 ServiceNow 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 ServiceNow};OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;")
