Please help me, I'm stuck Third stage HIU

After following all steps for HIU
I received a webhook from health-information/hiu/on-request
{
“requestId”: “7cc14b95-80d6-4a82-814d-84fb6fd42b82”,
“timestamp”: “2021-10-14T12:45:12.553819”,
“hiRequest”: {
“transactionId”: “a41e77ad-f531-49ab-8fc5-9584a4817401”,
“sessionStatus”: “REQUESTED”
},
“error”: null,
“resp”: {
“requestId”: “4cb65d29-7419-425a-a79f-57283719f9c8”
}
}

Im clue less what to do with this response after that ?
How will i get the data ?
