Updates from Klaviyo 3
- identified
Some customers and third-party apps connected to Klaviyo accounts are experiencing delays receiving event webhooks. Webhook actions in flows are not affected at this time. To support recovery, we temporarily paused processing of new webhooks at 5:11 PM US/Eastern on October 22, 2026, and earlier webhooks are still being delivered with delays. Webhook data is being retained, and we expect delayed and paused webhooks to be delivered once processing resumes. We are working to resolve this as quickly as possible and will share another update shortly.

New event webhooks are being delivered again after processing resumed at 11:28 PM US/Eastern on October 22, 2026. Some customers and third-party apps connected to Klaviyo accounts may continue to see delays while the backlog is processed, and we expect these delays to decrease over time. Webhook data has been retained, and webhook actions in flows are not affected at this time. We continue to monitor closely and appreciate your patience throughout this incident.
