execPayPal :: FromJSON a => EnvironmentUrl -> ClientID -> Secret -> PayPalOperations a -> IO (Either PayPalError a)

Authenticate with PayPal and then interact with the service.

execPayPalOpers :: EnvironmentUrl -> ClientID -> Secret -> AccessTokenWithExpiration -> PayPalOperations a -> IO (Either PayPalError (a, AccessTokenWithExpiration))

Executes a PayPalOperations monad as IO. Because the access token can expire and needs to be renewed, this function returns the desired value and the most current access token when successful.
