With Share-to-get offers, your customers can choose to share on Facebook or Twitter to get your gift:

Share to Get offer

As Twitter doesn't provide information to detect if a tweet has been shared or not, the only solution is to show the coupon few seconds after customers click "Share".

However, with Facebook, only after customers share your products, they will get the coupon code. Therefore, you can enable Facebook sharing only and disable Twitter if you want.
