I'm new to Zoho (and JSON) I'm trying to create a webhook using JSON.  The webhook creation interface appears to be very rudimentary.  On the Webhook creation screen under "Parameters in the User Defined Format(XML, JSON, etc.)"

The insert is just a one line text field.  That seems like not very useful for building a JSON request, especially for someone just learning the JSON format.  

Can anyone show me a simple example of how a JSON request would look inside that text field for just say, posting an account_id and account_name from the accounts module (or something similar?)
