Hi @justrsin, welcome to the community!
This is a rather old topic, so can easily be overlooked. Perhaps you could open a new thread and provide the relevant information requested in the template popping up when doing so?
With trigger/webhook trouble specifically it’d also be good to understand how your webhook URLs look like (you can view them in your trigger node) and whether webhooks other than the ones from Woocmmerce are working fine for you.
