def success?
  true
end

#valid? ⇒ Boolean

To allow manual payment method we verify that the provided checksum corresponds to the one we can calculate with the provided params in the form.

This avoids forging a request with ‘manual_payment` in the URL for a cart which was not set to use this method, thus allowing people to validate orders without paying them.

Returns:

  • (Boolean)
