Is s2member provide any button for the refund transaction from the paypal using transaction id

[Vinita]

I am searching for the method to get the s2member button for the refund amount through paypal using transaction id.

You refund using the PayPal interface and the s2Member gets notified via IPN and demotes the user’s subscription accordingly.
