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

// 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("CkStringBuilder")

// 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

// 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
