This custom shortcode allows your users to convert their myCRED points into a WooCommerce coupon, in order to give themselves a discount or partial payment on their order. In order for this to work, you need to set an exchange rate between points and your store currency and select. Requires myCRED 1.6+ and WooCommerce 2.4+

Hi,
This is a great script!

May I know where or how do I set the requirements for user to convert?

1. limit the number of times to convert, to prevent user separate the cart to make purchase
2. the promo code to that particular user
3. set expiry date. and if once expired, the points will return back to the user

Thanks!

hey, great snippet! is it possible that this is only possible for a few specific products? maybe id = 111, 234 & 6096?
