I started using ZOHO CRM API.

It is mentioned in the API that records can be inserted using the below url in xml format 

https://crm.zoho.com/crm/private/xml/Leads/insertRecords?authtoken=Auth Token&scope=crmapi&xmlData=Your XML Data

But I want to insert records in Json format and I am using Java.

Can anyone tell me how can I achieve this?

Thanks in advance
