Order ID not returning after payment successful

Hi Team,

We integrated the layer payment approach for our website. After payment successfully, we are not getting the Order ID which was showing at the time of transaction.

Endpoint: https://sandbox-payments.open.money/layer

Request:

{
'amount': 10.00,
'contact_number': "9876543210",
'email_id': "[email protected]",
"currency": INR,
'mtx': uniqid()
}

Response:

{
payment_id: "sb_py_BR7WtRUsv1bUMHh",

payment_token_id: "sb_pt_BR7WtH8vadZ0iMu",

status: "captured"

}
Kindly help us to get the Order ID so that we can track the transaction after payment success.
