Default Subscription expiry time for office365 managment API RRS feed

  • Question

  • I am subscribing to the office365 management API using the below URL

    HTTP Request body is
    'webhook': {
    'address': 'https://<publicip>:9216/webhook/office365?apikey=N9jxvydjHi5wqmHIpPa2kbvylqHrGo4O',
    'expiration' : '2030-12-12'

    I am successfully subscribed with office365 management API, but in the above HTTP request body  'expiration'  value I have mentioned as '2030-12-12', does it mean that subscription is valid that time.
    If We do not provide the expiration value in the request, what is default value for expiration.
