Listeners object

The listeners object helps you keep track of events in the module and respond accordingly.

The following events are available:

Event	Expected data	Description
close	undefined	It's triggered when the user closes a widget.
error	{ name: String; message: String; }	Widget error message (not payment-related), see error codes.
loaded	undefined	It indicates the module is loaded with necessary data and ready to receive extra data if needed. This event may duplicate if the user is redirected to their bank's 3-D Secure verification page.
payment-status	{ status: String payment_id: String order_id: String tx_id: String // if available }	Possible statuses: `pending`, `canceled`, `failed`, `success`, `failover`. Events may not be unique for each status. `tx_id` appears in the `pending` status.
position	{ step: String }	Notifies changes in user flow position.
rate-update	{ ticker: String, fee_percent: String, currency_amount: String, fee_amount: String, commodity_amount: String, purchase_amount: String, miner_fee: String, currency_miner_fee: String }	Updates when the widget rate changes. We fix the exchange rate for 30 seconds.

Add the listeners object like this: the key is the event type, and the value is your callback function.

const widget = new WertWidget({
  ...options,
  listeners: {
    position: (data) => console.log("step:", data.step),
  },
});

To subscribe to the payment status data, you can do the following:

const widget = new WertWidget({
  ...options,
  listeners: {
    'payment-status': data => console.log('Payment status:', data)
  },
});

This will only be triggered when simulating the purchase, not in intermediary steps.
