Hi @LPatPSP,
After consulting with some colleagues, retrying is not a supported option for webhooks.
However, you might consider this workaround:
Log an event if and when a webhook fails. Then, run a scheduled search to check for these failure events and alert on them. Set up a webhook alert action on this alert. The webhook can retry the original request. Note that the log event might need to include the original data payload from the first webhook notification.
Hope this is helpful!
