Two Ways Changes Are Tracked
Tag History records tag changes through two methods. The method used determines whether the change is attributed to a specific user.1. Webhooks (Automatic)
Shopify sends the app a notification whenever an order, product, or customer is updated. Tag History compares the new tags to the previously recorded state and saves any additions or removals.- Works automatically in the background — no action needed from your team
- Captures changes made anywhere: Shopify Admin, other apps, bulk edits, API
- Attribution shows as “Shopify Admin” because Shopify doesn’t tell us which user made the change
2. In-App Extension (With Attribution)
When a team member uses the Tag History block on an order, product, or customer page to add or remove a tag, the change is recorded with their name.- Shows the actual user name in the history timeline
- Supports optional comments to explain why a tag was changed
- The only way to capture user-level attribution
If you want to know who made a tag change, use the Tag History extension block rather than Shopify’s native tag field. Both result in the same tag being saved on the entity — the difference is attribution.
What Gets Recorded
Every tag change entry stores:User Attribution Explained
The “Changed by” field shows who made the change when we can determine it.Named user (e.g., 'Jane Smith')
Named user (e.g., 'Jane Smith')
The change was made through the Tag Historian extension block. The user was logged in to Shopify Admin and their identity was captured.
"Shopify Admin"
"Shopify Admin"
The change was detected via webhook — meaning it was made somewhere else (native Shopify tag field, another app, CSV import, API, bulk edit). We know the tag changed but not who changed it.
Free Plan Usage Limits
On the Free plan, Tag History records up to 30 tag changes per month. Once the limit is reached:- New tag changes are not recorded until the 1st of next month
- Existing history remains fully accessible
- A warning banner appears in the dashboard and extension blocks
- You can upgrade to Premium at any time for unlimited tracking
The counter resets automatically on the 1st of each month. Upgrading to Premium removes the limit entirely.

Tag history is stored indefinitely while the app is installed. There is no automatic expiry. All data is permanently and immediately deleted when the app is uninstalled.Entities Tracked
