Disconnecting a store stops its syncs and deletes everything Merchant Sheets holds for it. If you only need to change the store's keys, update them instead, which keeps all your data.
Disconnect a store
Disconnecting can't be undone. Merchant Sheets deletes the store's synced orders, products, inventory, and other data, plus the app keys you gave us.
In the web app, go to Data Connectors.
Next to the store, select Disconnect.
Type the store's .myshopify.com address to confirm.
Select Disconnect and delete data. Syncing stops right away.
What happens after you disconnect
Your data: Usually deleted within minutes, and always within 30 days. Data Connectors tells you if any is still being removed.
Saved queries: They stay, but return no rows for that store.
Your workbooks: Tables already in your sheets keep their numbers until you refresh them. After a refresh, that store's rows are gone.
Your plan: The store no longer counts toward your plan's store limit.
The Shopify app: It stays installed on your store. Delete it in your Shopify Dev Dashboard if you no longer need it.
Uninstalling the app in Shopify
Deleting or uninstalling the Merchant Sheets app in Shopify stops new syncs, and Data Connectors shows the sync as failed. It doesn't delete what Merchant Sheets already holds. To delete that data, disconnect the store in Merchant Sheets too.
Connect a store again
To use a disconnected store again, connect it the same way you did the first time, following Connect your Shopify store. It syncs from scratch and gets a new history start date.
If you reconnect within a few minutes of disconnecting, you may see a message that the store is still being disconnected. Wait a few minutes and try again.
Update keys without disconnecting
If you created a new app or reset its Client secret, update the keys on the store you already have connected. Your data and history stay as they are. Update your Shopify app credentials has the steps.
