Custom Shopify webhooks, metaobject topics, metafields in webhooks

Mechanic now supports custom Shopify webhooks.

This gives advanced users a new way to receive Shopify webhook events in Mechanic, with Shopify filtering deliveries before they arrive, customizing payload fields, including metafields, and routing events onto custom event topics.

This also unlocks something new for Mechanic: Shopify metaobject webhook event topics.

You can now create custom Shopify webhooks for:

Each metaobject webhook uses a filter, so you can subscribe to the exact metaobject definition your task cares about. This filter is required by Shopify.

With a regular subscription, every enabled task listening to that topic receives every product update. If you have 20 product-update tasks, all 20 are triggered, and each task has to decide whether the update matters.

We also cleaned up Mechanic’s Settings area, removing the old tab layout and making the growing set of settings easier to scan and navigate.
