Klaviyo Shopify Integration Not Syncing

How to fix it

Try these in order — the most common fix is first.

1. 1. Re-authenticate Shopify

   Copy steps
   1. In Klaviyo open Integrations and select Shopify
   2. Re-authenticate with Shopify
   3. If it persists, remove and re-enable the integration and wait about 24 hours for a re-sync
   Did this fix it? Yes No

2. 2. Check events, not just status

   Copy steps
   1. Open the Placed Order metric activity feed and look at the latest event date
   2. A 'complete' historical sync doesn't prove new orders are arriving
   Did this fix it? Yes No

3. 3. Fix the onsite pixel

   Copy steps
   1. Confirm the Klaviyo app embed is enabled in the Shopify theme
   2. If Viewed Product or Added to Cart events are missing, check the Shopify customer privacy settings; a pixel stuck on awaiting consent blocks them
   Did this fix it? Yes No

4. 4. Find rejected profiles

   Copy steps
   1. Open the affected profile and read the sync failure reason
   2. Use the Sync failed filter to list all rejected profiles
   3. Check whether double opt-in is blocking new profiles
   Did this fix it? Yes No
