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

* Use the Chilkat Email API to create or load an email.
loEmail = CreateObject('Chilkat.Email')

* The From name/address don't need to be specified. 
* GMail will automatically use your Gmail address if the following 2 lines are omitted.
loEmail.FromName = "My Name"
loEmail.FromAddress = "my_account_name@gmail.com"

loEmail.AddTo("John Smith","somebody@somewhere.com")
* To add more recipients, make additional calls to AddTo or AddCC, one per recipient...

loEmail.Subject = "This is a test GMail email created using Chilkat."
loEmail.Charset = "utf-8"
loEmail.AddPlainTextAlternativeBody("This is a test")

* Create an HTML email body with an embedded image.
lcCid = loEmail.AddRelatedFile("qa_data/jpg/starfish.jpg")
loSbHtml = CreateObject('Chilkat.StringBuilder')
loSbHtml.Append('<html><body>This is a <b>test</b><br><img src="cid:STARFISH_CID"/></body></html>')
lnNumReplacements = loSbHtml.Replace("STARFISH_CID",lcCid)

loEmail.AddHtmlAlternativeBody(loSbHtml.GetAsString())

* Add some attachments..
lcMimeType = loEmail.AddFileAttachment("qa_data/helloWorld.pdf")
IF (loEmail.LastMethodSuccess <> 1) THEN
    ? "Failed to add PDF attachment."
    RELEASE loEmail
    RELEASE loSbHtml
    CANCEL
ENDIF

lcMimeType = loEmail.AddFileAttachment("qa_data/msword/sample2.docx")
IF (loEmail.LastMethodSuccess <> 1) THEN
    ? "Failed to add MS-Word attachment."
    RELEASE loEmail
    RELEASE loSbHtml
    CANCEL
ENDIF

* OK.. we now have an HTML email with 2 attachments..
loSbMime = CreateObject('Chilkat.StringBuilder')
loEmail.GetMimeSb(loSbMime)

* Send the email.  (GMail has a 5MB limit on the total email size.)
loHttp = CreateObject('Chilkat.Http')
loHttp.AuthToken = "GMAIL-ACCESS-TOKEN"

* Send using the simple upload request for the Gmail API
lcUrl = "https://www.googleapis.com/upload/gmail/v1/users/me/messages/send?uploadType=media"
lnSendGzipped = 1

loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpSb("POST",lcUrl,loSbMime,"utf-8","message/rfc822",loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loEmail
    RELEASE loSbHtml
    RELEASE loSbMime
    RELEASE loHttp
    RELEASE loResp
    CANCEL
ENDIF

* A status code of 200 indicates success.
? "Response status code: " + STR(loResp.StatusCode)
? "Response body:"
? loResp.BodyStr

* The response body contains JSON.
* Use the online tool at Generate JSON Parsing Code
* to generate JSON parsing code.

* A sample successful JSON response:

* {
*  "id": "166f0d4ac39e50bf",
*  "threadId": "166f0d4ac39e50bf",
*  "labelIds": [
*   "SENT"
*  ]
