Safer Klaviyo settings with valid API keys
May 06, 2026
Saving Klaviyo settings now requires a working API key, so merchants are less likely to leave a broken connection in place. The Klaviyo integration is also available without the previous limited-access restriction.
Summary
- Invalid Klaviyo API keys can no longer be saved
- Klaviyo integration is available to more merchants
- Settings stay usable only with a working key
