{% hint style="info" %} This FAQ is about Shopify events specifically. For a more general treatment of this question, refer to Why don't I see any events in my task's activity?. {% endhint %}
Start by checking status.mechanic.dev and shopifystatus.com for service interruptions. (If you're not signed up for Mechanic status notifications, this is a good time to take care of that!)
If the event is well and truly missing, email team@usemechanic.com for further assistance.
