Points Exchanges gives you the ability to bring to your users the possibility to exchange any or a predefined points amount to any other points type.
First of all, you need to configure the exchange rates between the different points types you setup.
You can place a points exchange form anywhere, including in-line on any page or post, using the [gamipress_points_exchange] shortcode to allow exchange points.
In addition, you can announce the current available exchange rates through the [gamipress_points_exchange_rates] shortcode.
Also, you can place a purchase form on any sidebar through widgets provided by this add-on.
