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

    let http = CkoHttp()!

    // 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).

    http.authToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

    let sbResponse = CkoStringBuilder()!

    // 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
    http.clearUrlVars()
    http.setUrlVar("userPrincipalName", value: "chilkatsoft@outlook.com")
    var success: Bool = http.quickGetSb("https://graph.microsoft.com/v1.0/users/{$userPrincipalName}/mailFolders", sbContent: sbResponse)
    if (success != true) && (http.lastStatus.intValue == 0) {
        print("\(http.lastErrorText!)")
        return
    }

    let json = CkoJsonObject()!
    json.loadSb(sbResponse)
    json.emitCompact = false

    print("Status code = \(http.lastStatus.intValue)")
    if http.lastStatus.intValue != 200 {
        print("\(json.emit()!)")
        print("Failed.")
    }

    print("\(json.emit()!)")
    print("----")

    // 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:
    var i: Int = 0
    var numFolders: Int = json.size(ofArray: "value").intValue
    while i < numFolders {
        json.i = i
        print("\(json.string(of: "value[i].displayName")!)")
        i = i + 1
    }

    // The output from the above loop:

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