Meta's whatsapp API integration and response on webhook,

https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks/payload-examples

I am new to the whatsapp cloud integration and I am confused why inbound message response of webhook is too weird with nested array, in which cases facebook(meta) will give an multiple elements in nested of nested array. Is it good way to get entry[0].changes[0].value.messages[0].text.body or I require to add loop on every case? What are the changes we will received multiple elements?

{
  "object": "whatsapp_business_account",
  "entry": [{
      "id": "WHATSAPP_BUSINESS_ACCOUNT_ID",
      "changes": [{
          "value": {
              "messaging_product": "whatsapp",
              "metadata": {
                  "display_phone_number": PHONE_NUMBER,
                  "phone_number_id": PHONE_NUMBER_ID
              },
              "contacts": [{
                  "profile": {
                    "name": "NAME"
                  },
                  "wa_id": PHONE_NUMBER
                }],
              "messages": [{
                  "from": PHONE_NUMBER,
                  "id": "wamid.ID",
                  "timestamp": TIMESTAMP,
                  "text": {
                    "body": "MESSAGE_BODY"
                  },
                  "type": "text"
                }]
          },
          "field": "messages"
        }]
  }]
}

You can read the documentation of graph-api webhook,
https://developers.facebook.com/docs/graph-api/webhooks/getting-started#validate-payloads

Event Notifications are aggregated and sent in a batch with a maximum of 1000 updates. However batching cannot be guaranteed so be sure to adjust your servers to handle each Webhook individually.

You can also check the property-wise batch possibility in the provided link.
