{
   "subscriptions": null,

            },
            "blocked_value": {

         }
      ],
      "securities": [
         {
            "figi": "BBG004S683W7",
            "blocked": 0,
            "balance": 10,
            "position_uid": "8615c3f2-758c-42be-a69d-c97ac9d95f04",
            "instrument_uid": "1c69e020-f3b1-455c-affa-45f8b8049234",

      "date": "2023-12-25T10:01:36.457517Z"
   },
   "ping": null
}

Но обычно ответ такой:

{
   "subscriptions": {
      "accounts": [
         {
            "account_id": "2103311XXX",
            "subscription_status": 1
         },
         {
            "account_id": "2103434YYY",
            "subscription_status": 1
         }
      ]
   },
   "position": null,
   "ping": null
}

А ещё чаще вот такой:

{
   "subscriptions": null,
   "position": null,
   "ping": {
      "time": "2023-12-25T14:49:19.658264Z"
   }
