What happens when the server that is setup to receive callbacks isn’t available due to a network issue or an issue with the server itself. Are any attempts made to retry the notification. Also, are there any suggestions on how to handle the integration situation if it isn’t possible to receive callbacks due to firewall rules? Should the integrator create some sort of polling to check the status of open packages and their signers that it has sent or is there a better solution?
The esignlive application only makes one attempt at notifying your listener. If for any reason the callback fails, then you will receive an email notification. There won’t be any attempts to resend notifications for an event. As for your second question, the backup plan should indeed be polling.
