update creator's entry via email/webhook?

hi

via workflow customers receive entry data in manner "if this than that"
and via email they can reply "accepted" or "rejected"

in email subject / message body there is for identification unique zoho creator's entry id
how can i via customer's reply update currect entry status?

first variant - work with reply email and via entry id update entry
second variant - i can make email-to-webhook and via webhook update entry

question - is there any possibilities in updating zoho entries via email / webhook?
