    Hi Achintya,

    WhoID in Salesforce refers to people things. So that would be typically a Lead ID or a Contact ID. The WhoId represents a human such as a lead or a contact. WhoIds are polymorphic. Polymorphic means a WhoId is equivalent to a contact’s ID or a lead’s ID. The label is Name ID.
    WhatID in Salesforce refers to object type things. That would typically be an Account ID or an Opportunity ID. The WhatId represents nonhuman objects such as accounts, opportunities, campaigns, cases, or custom objects. WhatIds are polymorphic. Polymorphic means a WhatId is equivalent to the ID of a related object. The label is Related To ID.
