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

Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    email := chilkat.NewEmail()

    // This example chooses to load an email from a file.
    success = email.LoadEml("qa_data/eml/testEmail.eml")
    if success == false {
        fmt.Println(email.LastErrorText())
        email.DisposeEmail()
        return
    }

    // Get the email as MIME.
    sbMime := chilkat.NewStringBuilder()
    email.GetMimeSb(sbMime)

    http := chilkat.NewHttp()
    resp := chilkat.NewHttpResponse()

    http.SetAuthToken("GMAIL-ACCESS-TOKEN")

    // Upload to GMail (does not send, but just inserts).

    // 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.
