**Note:** we will *automatically* prefix your partner/shop name in front of the event. For example, if sending an event called "OrderPlaced", we'll show it in our UI as "[Your Partner/Shop Name] - OrderPlaced" to distinguish it from others of a similar name.

ID of the subscriber the event should be associated with.

An external id to store for this event. This is for your own purposes and is optional. We'll set a default if you do not include it in your calls that's based on the time and date the event was received.
