Once tickets have been purchased and delivered to the customer, you'll likely need a way to validate their ticket purchase at the venue on the day of the event. This is where the "Check In" functionality comes in handy.
Events provides a simple controller action endpoint for you to trigger. This will also check if a customer has already checked in, preventing ticket re-use.
Additionally, if producing a PDF template using our example, a QR code will be generated. This code is the full URL to this action endpoint.
Simply trigger the following action URL in your templates:
actions/events/ticket/checkin?sku=<sku>
<sku>: This is the ticket SKU which gets generated automatically at the purchase of the ticket. This SKU is unique.The controller returns a JSON response. On an error the response contains a simple error message. On success the response contains following:
success: Contains the string "Ticket checked in.".checkedInDate: The check in date in DATE_ATOM (opens new window) format.There are a number of ways you could setup this mechanism, but commonly you could setup a simple form on your website to allow staff at the door to check a customer in. Something similar to the below:
<form method="post" accept-charset="UTF-8">
<input type="hidden" name="action" value="events/ticket/checkin">
<input type="text" name="sku">
<input type="submit" value="Check in to event">
</form>
