Adding email through API

Adding email through API

I'm currently working on a system that syncs with Zoho. 

We want to be able to track the emails we send (through our system) to a Contact using Zoho CRM.

We want to track the email as if we sent it from the Zoho CRM (like the picture below) even if the email was sent from our system.



The sending of the email though is done by our application, so we'd like to know if we could use the API to insert a new row to the emails of a contact so we could keep track of it.

Any help on this would be appreciated.
