Question

WooCommerce completed orders missing in Klaviyo despite webhook 200 OK responses

My WooCommerce integration is enabled, but completed orders are not appearing as purchase events in Klaviyo.

Website: https://experiencebee.com
Klaviyo Site ID: W8e8j4
Klaviyo WordPress plugin: 3.8.3, active

Findings:

  • A paid order completed July 27, 2026 is missing from the matching billing-email profile. That profile shows Started Checkout but no purchase events.

  • Test order #16852 completed October 5, 2026 using a 100%-off coupon ($0 total).

  • Its matching Klaviyo profile also shows Started Checkout but no Placed Order, Ordered Product, or Fulfilled Order.

  • All five Klaviyo webhooks are Active.

  • The test order’s order.created and order.updated deliveries both received HTTP 200 OK at approximately October 6, 2026, 01:55:36 UTC.

  • The webhook destination’s account identifier matches my Klaviyo Site ID.

Please investigate why these acknowledged order notifications are not producing purchase events, including whether orders going directly to Completed affect processing. Please also advise how to recover missing historical order data safely.

I can provide the webhook logs and screenshots.

Hi Jeannie, 
Thank you for sharing all of those details for us to take a deeper look into this for you! 

I do see a periodic sync issue on the backend for your WooCommerce integration so I went ahead and re-ran that. I also ran an order resync for June 1st-today to hopefully capture any missing orders during this period. 

When investigating this order number: #16852 on the backend, I did see some 401 authorization issues. 

Can your team navigate to your WooCommerce integration: https://www.klaviyo.com/integration/woocommerce the re-authenicate from the bottom left of the page and save this? 

Once this is properly restored in authentication status, feel free to follow up on this post or via Community DM and I can run another sync for you!

Meghan, Thanks so much for these simple instructions! I was able to follow them perfectly without issue, and would now appreciate if you’d run another sync for us. Best, Jeannie with Experience Bee
