Zoho CRM convert lead api not working for me.

Zoho CRM convert lead api not working for me.

Hi Zoho Community

I want to use Zoho CRM's convert lead API in our backend server to convert lead to deals.
I am passing the following input:
{
      overwrite: true,
      NotifyLeadOwner: true,
      Deals: {
                        DealName: "Sanika Yerawar",
                        ClosingDate:"19-Jan-2022",
                        Stage:"Scanning Scheduled",
                  }
}.

But the response I am getting from Zoho is an empty response, with no data even for status of the API action. Could anyone guide me further on how to debug this API?
