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

loHttp = CreateObject('Chilkat.Http')

* Use your previously obtained access token here:
* See the following examples for getting an access token:
*    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
*    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
*    Refresh Access Token (Azure AD v2.0 Endpoint).
*    Refresh Access Token (Azure AD Endpoint).

* To send email, we'll POST to the following endpoint:
* 
* POST /users/{id | userPrincipalName}/sendMail
* 
* (The special keyword "me" may be used in place of a principal name.)
* 

* The body of the POST request will contain the MIME source of the email in base64 format.

* Create a new email object
loEmail = CreateObject('Chilkat.Email')
loEmail.Subject = "Test Outlook API to Send HTML Email with Attachments"
loEmail.From = "Mary <mary@somewhere.com>"
loEmail.AddTo("Joe","joe@example.com")

* Add a plain-text alternative body, which will likely never be seen.
* (It is shown if the receiving email client is incapable of displaying HTML email.)
loEmail.AddPlainTextAlternativeBody("This is a plain-text alternative body...")

* Our HTML will include an image, so add the related image here.
lcContentIdStarfish = loEmail.AddRelatedFile("qa_data/jpg/starfish.jpg")
IF (loEmail.LastMethodSuccess = 0) THEN
    ? loEmail.LastErrorText
    RELEASE loHttp

    RELEASE loEmail
    CANCEL

* The src attribute for the image tag is set to the contentIdStarfish:
loSbHtml = CreateObject('Chilkat.StringBuilder')
loSbHtml.Append("<html><body><p>This is an HTML email with an embedded image.</p>")
loSbHtml.Append('<p><img src="cid:CONTENT_ID_STARFISH" /></p></body></html>')
lnNumReplacements = loSbHtml.Replace("CONTENT_ID_STARFISH",lcContentIdStarfish)

loEmail.AddHtmlAlternativeBody(loSbHtml.GetAsString())

* Finally, add some attachments to the email.
* Add a file attachment.
lnSuccess = loEmail.AddFileAttachment2("qa_data/pdf/fishing.pdf","application/pdf")
IF (lnSuccess = 0) THEN
    ? loEmail.LastErrorText
    RELEASE loHttp
    RELEASE loJsonToken
    RELEASE loEmail
    RELEASE loSbHtml
    CANCEL
ENDIF

* Add an attachment where the content is contained in a string.
lcContent = "This is the content of the 2nd attached file."
loEmail.AddStringAttachment("someText.txt",lcContent)

* Get the email as multi-line base64..
loBdMime = CreateObject('Chilkat.BinData')
loEmail.GetMimeBd(loBdMime)

* Now get it as multi-line base64
loSbBase64 = CreateObject('Chilkat.StringBuilder')
loBdMime.GetEncodedSb("base64_mime",loSbBase64)

* Send the HTTP POST (i.e. send the email)
loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpSb("POST","https://graph.microsoft.com/v1.0/me/sendMail",loSbBase64,"utf-8","text/plain",loResp)
IF (lnSuccess = 0) THEN

    RELEASE loJsonToken
    RELEASE loEmail
    RELEASE loSbHtml
    RELEASE loBdMime
    RELEASE loSbBase64
    RELEASE loResp
    CANCEL
ENDIF

* The send succeeded if the response status code = 202.
* In the success case, there is no response body.  (We just get the response code to know that it succeeded.)
IF (loResp.StatusCode <> 202) THEN
    loJson = CreateObject('Chilkat.JsonObject')
    loJson.Load(loResp.BodyStr)
    loJson.EmitCompact = 0
    ? loJson.Emit()
    ? "Failed, response status code = " + STR(loResp.StatusCode)
