Aside from the API, there's also webhook to listen for the trade status:

const onMessage = (event) => {
	// put your transaction event handler
	console.log(event.data);
}

// create tramsaction
const transaction = await BI.convert({
	inputCurrency: 'IDR',
    outputCurrency: 'BTC',
    phoneNumber: '08123456789',
    amount: 100000,
    username: 'anon',
    address: '3GB8jS8QGutd6bJWuSb3gF1WULf2Ut55KA',
    source: 'input',
});

const orderId = transaction.data.orderId;

// start listen
BI.listenStatus(orderId, onMessage);
