If you go look at the API doc on https://www.zoho.com/zeptomail/help/api/email-sending.html (which was the first result from googling "zeptomail api") it says "From", "JSON Object", "Allowed value - A valid sender email address with "address" and "name" key-value pairs."

So, try perl like:

from => { address => "noreply@email.com", name => "No Reply" },
