This API is currently in Beta. The Exotel Heartbeat API monitors the health of your Exophone in real time. The API notifies the ‘health’ of an Exophone based on which actions can be taken at your end. This webhook will ping information about your ExoPhone health as configured. The URL endpoint will receive heartbeat notifications continuously at the frequency you set. The Heartbeat API can help gain visibility into the operational health of your Exophone by continuously initiating calls across different combinations of Exophones to derive its status. This information is useful to understand if fallback options are needed. Exotel is an Asia cloud telephony company, that provides communications infrastructure services.
