Does Zoho crm supports insertRecords as post body?

To insert a contact, I've used below URL.

https://crm.zoho.com/crm/private/xml/Contacts/insertRecords?authtoken=d3c628d4a475fe89b37a33abffcbdf84&scope=crmapi&newFormat=1&xmlData=  <Contacts> <row no="1"> <FL val="First Name">Scott</FL> <FL val="Last Name">James</FL> <FL val="Email"> test@test.com</FL> <FL val="Department">CG</FL> <FL val="Phone">999999999</FL> <FL val="Fax">99999999</FL> <FL val="Mobile">99989989</FL> <FL val="Assistant">John</FL> </row> </Contacts>

xmlData parameter added to this URL and tested in Postman which is working fine.
1. Is there any way to send my xmlData in post body instead of appending to url parameters?
2. Still zoho crm doesn't support insert records in json format?

Thanks for the help.
