* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.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")
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
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())

* OK.. we now have an HTML email with an embedded JPG image
* We'll need to get the full MIME of the email encoded to a base64url string.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbMime = CreateObject('Chilkat.StringBuilder')
loEmail.GetMimeSb(loSbMime)
loSbMime.Encode("base64url","utf-8")

* The body of the HTTP request will be JSON..
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateSb("raw",loSbMime)

* Send the email...
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')
loHttp.AuthToken = "GMAIL-ACCESS-TOKEN"

lcUrl = "https://www.googleapis.com/gmail/v1/users/me/messages/send"
loResp = loHttp.PostJson3(lcUrl,"application/json",loJson)
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loEmail
    RELEASE loSbHtml

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

* 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"
