The customer can set up callbackURL to be returned on completion of each step of the onboarding process of the investor. If this is set for a particular step, a JSON containing customerId, merchantId, status, pageName, and pageEventTimestamp is posted to the callback URL of that step.

# Expected Page Event Callback Response

```json
{
    "customerId": "..customerId..",
    "merchantId": "..merchantId..",
    "status": "draft",
    "pageName": "..pageName..",
    "pageEventTimestamp": "..pageEventTimestamp.."
}
```

**The below table describes the properties that are posted in the callback URL:**
