# Triggers
Triggers are used to transfer information. When you send data from your app to users' chatbots, you use triggers:
### Create Trigger
To create a trigger, follow steps 1 to 6 in the following screenshot:
Click on **Add Item** to specify what information to send back to the chatbot. For example, a payment status:
You can send as many items as you need. When there are too many items, you might want to use a JSON variable to package them. And specify the JSON variable as an item here instead.
{% hint style="info" %}
TIP
The app field you select here must be an existing field. You are unable to create a new field here. Please create it in the **App Fields** section.
{% endhint %}
### Fire Trigger
Wherever you need to notify an event or send data to chatbots, use a **Fire Trigger** action.
### Use Trigger
Thereafter, users can set up a flow to deal with the payment paid event, e.g. mark the order as paid, send a receipt, etc.
