### Handle Incoming Webhook Data
When configuring a webhook, it is imperative that the URL specified is capable of handling **POST** requests.
**API Request Retry Policy**
When initiating a request to a specified URL, the system will automatically attempt to connect up to three times at 30-minute intervals.
If, after three attempts, the URL remains unreachable, the data will be classified as an **undelivered record.**
Sample data payload that will be sent to the provided URL.
```json
{
"data": [
{
"id": "\\x1af00600",
"vid": 50,
"hour": 454682,
"block$": 56200,
"protocol": "\\x4200000000000000000000000000000000000010",
"timestamp": 1636856051,
"block_number": 56200,
"cumulative_transaction_count": 1621,
"cumulative_transfer_in_count": 1440,
...
},
{

},
{

}
]
}
