GET /status

uid, statusIndicator

Success Responses:

{
    "status": 200,

        "statusMessage": "SUCCESS"

}

Error Responses:

{
    "status": 404,
    "error": {
        "err-message": "PENDING"

}

Once the webhook is triggered:

{

        "statusMessage": "SUCCESS",
        "paymentType": 1,
        "paymentScheme": "CHINA_UNIONPAY",
        "txType": "ONE_TIME_PAYMENT"
    }
}

Once the webhook is triggered with failure transaction attempts:

{
    "status": 404,
    "error": {
        "err-message": "PENDING"
    },
    "failures": [
        {
            "payableTransactionId": "685e76b6-67a1-11ed-a333-e56ff946e0a9",
            "paymentMethod": 1,
            "payableOrderId": "oid-24cc0778-67a1-11ed-b7f5-8bd93b27f26c",
            "statusMessage": "FAILURE",
            "paymentType": 1,
            "paymentScheme": "MASTERCARD",
            "txType": "ONE_TIME_PAYMENT"
        },
        {
            "payableTransactionId": " c3ff309b-67a1-11ed-a333-51569715c33f",
            "paymentMethod": " 1",
            "payableOrderId": " oid-8f7aaaea-67a1-11ed-b7f5-99d7358edafa",
            "statusMessage": " SUCCESS",
