Retrieves a list of partner webhook topics. Use the subscription_status query parameter to filter the list as follows:

  • subscription_status=ALL returns all topics (ALL is the default value if query param not included)
  • subscription_status=SUBSCRIBED returns only topics to which I am subscribed
  • subscription_status=NOT_SUBSCRIBED returns only topics to which I am not subscribed

Currently, two webhook topics are available: billing tier upgrades (topic 1), and billing tier downgrades (topic 2).
