Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

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

http = Chilkat::CkHttp.new()

# 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.put_AuthToken("MICROSOFT_GRAPH_ACCESS_TOKEN")

sbResponse = Chilkat::CkStringBuilder.new()

# 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","chilkatsoft@outlook.com")
success = http.QuickGetSb("https://graph.microsoft.com/v1.0/users/{$userPrincipalName}/mailFolders",sbResponse)
if ((success != true) and (http.get_LastStatus() == 0))
    print http.lastErrorText() + "\n";
    exit
end

json = Chilkat::CkJsonObject.new()
json.LoadSb(sbResponse)
json.put_EmitCompact(false)

print "Status code = " + http.get_LastStatus().to_s() + "\n";
if (http.get_LastStatus() != 200)
    print json.emit() + "\n";
    print "Failed." + "\n";
end

print json.emit() + "\n";
print "----" + "\n";

# 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
numFolders = json.SizeOfArray("value")
while i < numFolders
    json.put_I(i)
    print json.stringOf("value[i].displayName") + "\n";
    i = i + 1
end

# The output from the above loop:

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