Let's say that you have multiple entrances to your event and you have created multiple API keys, one for each of the entrances so you can check after the event which entrance was the busiest. In such cases, this add-on becomes extremely handy as it adds another column to the table of the existing API keys within Tickera Settings -> API Access tab that displays the number of check-ins for each of the API keys.
This add-on is installed and activated like any other WordPress plugin and works with Tickera as a standalone as well as with Bridge for WooCommerce.
