Product triggers, step by step

Shopify Flow can tell you that a product was updated. It cannot tell you what changed, and it cannot tell you what the value was before. These eleven triggers do both: each one fires for one kind of change and hands your workflow the value before and after.

Every section below is a small tutorial: what makes the trigger fire, what arrives in Flow, and a workflow you can rebuild in a few minutes.

Product Update

Fires on every save of a product, whatever changed. Since 2.10.0 it also carries changes: the tracked fields that changed (title, handle, description, status, vendor, type, tags) with the value before and after.

Fires from	Shopify webhook plus change detection
Permission	Product, Variant & Collection Data Access
Switched on	Turning on a Flow workflow that uses it switches it on. Its own switch is on the app's Triggers page

Use it for

• One workflow that reacts to several kinds of product edits and branches on changes.fields.
• An audit trail: write every tracked change, old and new, to a sheet or a Slack channel.
• A catch-all while you find out which narrower trigger you really need.

What Product Update sends to your workflow

Variable in Flow	Type	What it holds
product	Product (Shopify)	The product that was updated. A full Shopify product, so all of its fields and Flow's own product actions are available.
payload	Text	JSON object containing the GID of the product that was updated (e.g. {"id":"gid://shopify/Product/123"})
changes	Object	Which tracked fields changed (title, handle, description, status, vendor, type, tags), with the old and new value of each
changes.fields	List of text	Names of the tracked fields that changed
changes.items	List of objects	Old and new value per changed field
changes.items (each).field	Text	The field that changed: title, handle, description, status, vendor, productType or tags
changes.items (each).oldValue	Text	The value before the update. Long values are shortened
changes.items (each).newValue	Text	The value after the update. Long values are shortened
eventId	Text	The id of this event. Search for it in the app's Event History to see exactly what was sent.

Example: Log every tracked product change with its old and new value

1. In Shopify Flow choose Select a trigger, open Workflow Trigger Extensions and pick Product Update.
2. Add a Condition: changes.fields Not empty and exists. Updates outside the tracked fields (a price edit, an image) arrive with an empty list and stop here.
3. Add Send internal email (or Send HTTP request to Slack). Flow's text fields accept Liquid, so a for loop over changes.items can print one line per change: the entry's field, then its oldValue and newValue, next to {{product.title}}.
4. Turn the workflow on. That switches the trigger on in the app as well.

Product Status Changed

Fires when a product moves between active, draft, archived and unlisted. A save that leaves the status alone does not fire it.

Fires from	Shopify webhook plus change detection
Permission	Product, Variant & Collection Data Access
Switched on	Turning on a Flow workflow that uses it switches it on. Its own switch is on the app's Triggers page

Use it for

• Tell the marketing team the moment a product goes live.

newStatus	Text	The new product status (active, draft, archived, or unlisted)
eventId	Text	The id of this event. Search for it in the app's Event History to see exactly what was sent.

Example: Announce a product that just went live

1. Pick Product Status Changed as the trigger.
2. Add a Condition: newStatus Equal to active, and a second criterion oldStatus Equal to draft.
3. Under Then add Send internal email: subject Now live: {{product.title}}, body with {{product.onlineStoreUrl}}.
4. Optional: add Add product tags with new-arrival so a collection picks it up.
5. Turn the workflow on.
