Are Paypal language options available in authorize.net paypal API? - paypal

Question

We have a few clients who need it so their visitors can start off on the Paypal login page in Spanish by default.
Paypal Express allows parameters to be passed into the setExpressCheckout URL, in order to set default locale and language.
Is there an equivalent of Paypal's LC or LOCALECODE parameters that can be set using the authorize.net Paypal functions, or a query string suffix that can be passed into the Paypal secure redirect URI, so that one can declare what language the Paypal login screen displays when Express checkout initiates?

Locale Codes
You can use any PayPal-supported language and locale to
localize PayPal checkout pages.
Localize the buyer's checkout experience Pass a locale code to PayPal
to customize the locale of the buyer's checkout experience.
PayPal payment buttons Merchants who use a PayPal payment button
(PayPal Payments Standard) can set the locale code using the lc
variable. To learn more about PayPal payment button HTML variables,
see HTML variables for displaying PayPal checkout pages.
Express Checkout Merchants who use the Express Checkout
SetExpressCheckout ( NVP, SOAP ) or Callback ( NVP ) API operations
can set the locale code using the LocaleCode parameter.
For an example, see changing the locale in the Express Checkout
integration guide.
And clicking the integration guide link:https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECCustomizing/#change-the-locale
Change the locale
You can change the locale of PayPal pages to match
the language on your website using either a 2-character country code
or a 5-character locale code from the supported codes listed on the
NVP/SOAP API locale codes page. To change the language displayed on
the PayPal pages, set the LOCALECODE parameter to one of the allowable
values in the SetExpressCheckout call.
Since authorize.net uses the Express Checkout API, is this option available?

Yes, you can pass this as a parameter which is then passed through to Paypal. The field is called paypalLc and is nested under createTransactionRequest -> transactionRequest -> payment -> payPal -> paypalLc.
