# Hook Structure

Delos webhooks contain a typed structure consisting of main fields and objects depending on the type of webhook

**Example**

```json
{
  //Unique Event ID (uuid4)
  "hook_id" : "string",
  //Webhook Type
  "hook_type" : int,
  "Data" : {
    // Object by webhook type
    // "Operation" : {}
    // or
    // "Client" : {}
    // or
    // "Account" : {}
    // or
    // "Counterparty" : {}
  }
}
```

### Webhook Types

Field `hook_type` is string value:

* 1 = OPERATION - Webhook contains Operation object
* 2 = DEPOSIT\_ACCOUNT - Webhook contains Deposit Account object
* 3 = CLIENT - Webhook contains customer object
* 4 = COUNTERPARTY - Webhook contains Counterparty (Beneficiar) object
* 5 = DEPOSIT\_ACCOUNT\_REQUISITE - Webhook contains Deposit Account object (Raised if requisites is changed)

Webhooks are sent whenever the status or state of the corresponding object changes.
