Hey @Enea,
Webhooks are almost always delivered within seconds of order creation. There are some factors that can affect this (temporary network issues, unusually high load on a server), but generally webhooks are delivered immediately.
However, as mentioned in our webhook documentation, webhooks shouldn't be relied on as the sole source of information for your app. It's possible for a webhook to be missed, and although our webhooks are generally reliable, we can't guarantee delivery 100% of the time so it's best to have another mechanism in place to look for anything that may have been missed. Implementing webhooks is a great way to be notified of events in real-time, and having that cron job in place can serve as a back-up in the very rare occurrence that a webhook isn't delivered.
If you're seeing instances of webhooks not delivering as expected, please provide the resource id (order_id, product_id etc) as well as an approximate time frame for when you expected to see it fire, and I can check our logs to hopefully help identify the issue.
