Lua Requires Chilkat v11.0.0+

Insert Email into GMail Folder

See more GMail REST API Examples

Directly inserts a message into only this user's mailbox similar to IMAP APPEND, bypassing most scanning and classification. Does not send a message.

This example will create a Chilkat Email object and upload/insert it into GMail. Then adds the "INBOX" label to the email to make it appear in INBOX

-- IMPORTANT: After uploading/inserting, you won't see the message in the Inbox.
-- In your web browser, if you go to "All Mail", you will see it.
