Hey Rob,
Thank you for taking the time to report this issue. Our webhooks queue can back up when there is a large number of orders being placed, but typically, webhooks will send within seconds. We are aware of the issue causing latency with webhooks triggering at the moment and working to resolve it as quickly as possible. Apologies for any inconvenience the delays may be causing you in the meantime.
We will report back once this issue is resolved and welcome any additional details you're open to sharing that may aid in our investigation in the meantime.
Best,
Natalie
