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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Use your previously obtained access token here:
loHttp.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

* This example will search /Inbox for a message we want to delete.
* First we need to get the folder ID for /Inbox.
* Then we'll search for messages based on some criteria, and delete the matching messages.

* Get the folder ID for /Inbox from the folder map created by this example 
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Hashtable')
loHtFolderMap = CreateObject('Chilkat.Hashtable')
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbMap = CreateObject('Chilkat.StringBuilder')
loSbMap.LoadFile("qa_data/outlook/folderMap.xml","utf-8")
loHtFolderMap.AddFromXmlSb(loSbMap)

* Get the ID for the "/Inbox" folder:
lcFolderId = loHtFolderMap.LookupStr("/Inbox")
IF (loHtFolderMap.LastMethodSuccess <> 1) THEN
    ? "Folder ID not found"
    RELEASE loHttp
    RELEASE loHtFolderMap
    RELEASE loSbMap
    CANCEL
ENDIF

lnSuccess = 1
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.EmitCompact = 0

* Search for emails in this folder with the phrase "Amazon SES" in the subject, and return only the id and subject.
loHttp.SetUrlVar("folder_id",lcFolderId)
loHttp.SetUrlVar("select","id,subject")
loHttp.SetUrlVar("filter","contains(subject,'Amazon SES')")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbResponse = CreateObject('Chilkat.StringBuilder')
lnSuccess = loHttp.QuickGetSb("https://graph.microsoft.com/v1.0/me/mailFolders/{$folder_id}/messages?$filter={$filter}&$select={$select}",loSbResponse)
IF (lnSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loHtFolderMap
    RELEASE loSbMap
    RELEASE loJson
    RELEASE loSbResponse
