'Updated by' from API calls

'Updated by' from API calls

Hi,
I have my PHP code working well connecting to the Zoho CRM API and doing updates to fields in the contacts module.  I would like to change the name of the user that is in the 'updated by' in the record.  For example, the timeline for any API updates shows that I am the user updating the record, where I would really like it to say something like 'updated by App Automation' or something like that.  Is this possible?
Thanks!
