Description

handle 5xx error for Volt payments webhooks

In the Volt connector for payment webhooks in production, a field is occasionally changing. The payment field sometimes comes as id instead, with the same expected value as payment. Since it’s coming as id rather than payment, the webhook body deserialization is failing, causing a 5xx error. To prevent this, I have added an alias for payment as id.

Check for webhooks in Volt dashboard under transactions.  
Then for Notifications check for all webhooks, In All the 4 notifications `PENDING ` , `COMPLETED`, `RECEIVED` and `REFUND_CONFIRMED ` should have status `Delivered` and http code `200 OK`.
