Extract individual values from JArray of Lists of JInts - json

Question

I am practising Scala and Akka Streams on Stripe-payment API. I am looking to extract the transaction date: created from the Json response.
This is the response (showing 2 transactions):
{
"object": "list",
"data": [
{
"id": "txn_1Fqdyl2eZvKYlo2CXfUAnz1z",
"object": "balance_transaction",
"amount": 10000,
"available_on": 1577145600,
"created": 1576581159,
"currency": "usd",
"description": null,
"exchange_rate": null,
"fee": 320,
"fee_details": [
{
"amount": 320,
"application": null,
"currency": "usd",
"description": "Stripe processing fees",
"type": "stripe_fee"
}
],
"net": 9680,
"source": "ch_1Fqdyk2eZvKYlo2CwjSNI1vO",
"status": "available",
"type": "charge"
},
{
"id": "txn_1Fqdyk2eZvKYlo2C7MuBhLpe",
"object": "balance_transaction",
"amount": 2000,
"available_on": 1577145600,
"created": 1576581158,
"currency": "usd",
"description": "テスト支払い",
"exchange_rate": null,
"fee": 88,
"fee_details": [
{
"amount": 88,
"application": null,
"currency": "usd",
"description": "Stripe processing fees",
"type": "stripe_fee"
}
],
"net": 1912,
"source": "ch_1Fqdyk2eZvKYlo2Ccg96i1QQ",
"status": "available",
"type": "charge"
}
],
"has_more": true,
"url": "/v1/balance_transactions"
}
It can vary from 1 to 100 transactions. So far I have been able to extract the value I need when there is only 1 transaction. I need to be able to extract values when there are multiple results. At the moment the value is hardcoded as: case Some(JArray(List(JInt(int)))).
My code:
def epochToDate(epochMillis: BigInt): String = {
val convertedToLong = epochMillis * 1000L
val df:SimpleDateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss")
df.format(convertedToLong)
}
val stripe = new Stream("txn_1Fqdyl2eZvKYlo2Cn0OSmwaY", "starting_after", hasMoreFromJson, 1, idFromJson)
stripe.asSource().runForeach(id => {
val rawValue = (parse(id) \ "data" \ "created").toOption
rawValue match {
case Some(JArray(List(JInt(int)))) => println("Date: " + epochToDate(int))
case _ => println("Value not present in JSON")
}
})

Try
val rawValue = (parse(id) \ "data" \\ "created").toOption
rawValue match {
case createdObjOpt: Option[JObject] =>
createdObjOpt match {
case Some(createdObj) =>
createdObj.obj.foreach { created =>
println(created)
}
case None => println("oh no!")
}
case _ => println("Value not present in JSON")
}
