Rails 4.2.4 error: ActionController::InvalidAuthenticityToken

[ziomio]

I am testing 2checkout in Sandbox env and upon redirecting back to my site I receive this error:

ActionController::InvalidAuthenticityToken at /billing/twocheckout_redirect
ActionController::InvalidAuthenticityToken

Just do skip_before_action :verify_authenticity_token to specific action
