Hi @moisb, you can put below code into your theme functions.php:

add_filter( 'add_to_cart_text', 'custom_add_to_cart_button_text' );
add_filter( 'woocommerce_product_single_add_to_cart_text', 'custom_add_to_cart_button_text' );

function custom_add_to_cart_button_text() {
  return __( 'Redeem', 'woocommerce' );
}
