Prevent redeeming a gift card via the URL

When a gift card email is received, there is a Redeem button which contains a URL with the gift card. When a customer clicks on the button, it will automatically apply the gift card to the cart.

If you do not want to allow a gift card to be applied to the cart via URL, perform the following steps:

1. Install the free Code Snippets plugin:
2. Create a new Snippet with the following code:

add_filter( 'pwgc_allow_applying_by_url', '__return_false' );

Note: if you prefer, add the code to your functions.php rather than using Code Snippets.
