Here is my problem: I would like to fetch all events related to a contact in my CRM.

In order to achieve this, I use the searchRecords function from the API.

I use this kind of URL:

URL: https://crm.zoho.com/crm/private/xml/Events/searchRecords?authtoken=myTokenHere&scope=crmapi

Post datas: criteria=(Who Id:1688544000000132002)

Of course I tried some different field name, like "Contact Name", "CONTACTID", "RELATEDTOID", "Who Id", "What Id" and everytime with both contact name or contact ID. None of these seems to work.

But it is working when I search on the subject, for exemple "criteria=(Subject:Test)" so I guess there is a way, I just can't find it out. So any clue would be greatly appreciated 

Cordialy,
