*  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).

loHttp.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

loSbResponse = CreateObject('Chilkat.StringBuilder')

*  Sends:  GET /users/{id | userPrincipalName}/mailFolders
*  Note: It is also possible to use the literal string "me" for the current logged-on user.
*  For example: GET /me/mailFolders
loHttp.ClearUrlVars()
loHttp.SetUrlVar("userPrincipalName","chilkatsoft@outlook.com")
lnSuccess = loHttp.QuickGetSb("https://graph.microsoft.com/v1.0/users/{$userPrincipalName}/mailFolders",loSbResponse)
IF ((lnSuccess <> 1) AND (loHttp.LastStatus = 0)) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loSbResponse
    CANCEL
ENDIF

loJson = CreateObject('Chilkat.JsonObject')
loJson.LoadSb(loSbResponse)
loJson.EmitCompact = 0

? "Status code = " + STR(loHttp.LastStatus)
IF (loHttp.LastStatus <> 200) THEN
    ? loJson.Emit()
    ? "Failed."
ENDIF

? loJson.Emit()
? "----"

*  In my test case, this is the result (see below)
*  Apparently, this lists folders without listing subfolders (aka child folders)
*  There's another REST API call to list child folders.

*  To iterate over the folders:
i = 0
lnNumFolders = loJson.SizeOfArray("value")
DO WHILE i < lnNumFolders
    loJson.I = i
    ? loJson.StringOf("value[i].displayName")
    i = i + 1
ENDDO

*  The output from the above loop:

*  	Archive
*  	Deleted Items
*  	Drafts
*  	Inbox
*  	Junk Email
*  	Outbox
*  	Sent Items

*  
*  The Microsoft Graph Outlook Mail API lets you read, create, and send messages and attachments, 
*  view and respond to event messages, and manage folders that are secured by Azure Active Directory 
*  in Office 365. It also provides the same functionality in Microsoft accounts specifically 
*  in these domains: Hotmail.com, Live.com, MSN.com, Outlook.com, and Passport.com.
