To connect to PayPal, you can use either a DSN or an ODBC connection string. Both of these methods use the sql package's Open function.

Connect to a DSN

To connect using a DSN:

db, _ := sql.Open("odbc", "DSN=CData PayPal Sys;")
defer db.Close()

Provide a Driver Connection String

To connect using an ODBC connection string:

db, _ := sql.Open("odbc", "DRIVER={CData ODBC Driver for PayPal};Schema=REST;InitiateOAuth=GETANDREFRESH;OAuthClientId=ClientId;OAuthClientSecret=ClientSecret; UseSandbox=true;;")
defer db.Close()
