Hooking Rule onto custom entity event

I am trying to write a custom event using WriteEvents endpoint, and I want to add a Rule which triggers only when a CONDITION happens on that event.

I can see my new custom event appearing in the Rules UI screen, but I dont see any attribute values for the conditions? For example, I have a "Player_Opened_Pack" event, and I want a rule to trigger if the CardsOpened is equal to 5. I have tried writing CustomTags with a key = PacksOpened and the value = the number, but I dont see how I can use this key/value inside of the conditions text box? It's not appearing there, and there's no documentation demonstrating how to do this, but I suspect it's possible.

Since the custom attributes are written in the Payload, so you can access the value you want with Payload.[Key]. You can refer to the Rule config below.

And here is the request body of WriteEvents API.

{
  "Events": [
    {
      "Entity": {
        "Id": "{
                {TitleAccountID}}",
        "Type": "title_player_account",
        "TypeString": "title_player_account"
      },
      "EventNamespace": "custom",
      "Name": "test_event",
      "Payload": {
        "Foo": "Bar"
      }
    }
  ]
}

thanks for sharing @Gosen Gao. What is the functional difference between Payload and PayloadJSON for WriteEvents?

There is not much difference here, just two ways to transfer the payload, using an object or using a Json string.

thanks @Gosen Gao. Is there a log somewhere that shows when a trigger is actually fired?
