To get calls records I'm using below api:
https://crm.zoho.com/crm/private/json/Calls/getRecords?authtoken=mytoken&scope=crmapi&fromIndex=1&toIndex=200&version=4

To get records of particular contact, how should i construct the query?

I did like below and its not working.
https://crm.zoho.com/crm/private/json/Calls/getRecords?authtoken=mytoken&scope=crmapi&fromIndex=1&toIndex=200&version=4&CONTACTID=2847269000000474021&RELATEDTOID=2847269000000474021

1. Is there any parameters to query by CONTACTID?

2. And, I want to get deleted records from server. Is there any api to get deleted records from portal?
