Double-check that you copied the full key without any leading/trailing spaces. Some platforms show a truncated preview — make sure to copy the full token. If the key was generated with restricted scopes, verify it includes the permissions listed above.
Check that your group has been granted access to this integration in On Belay → Groups → [your group] → Integrations. Also verify the specific scopes your group is permitted to use match what your query requires.
Some API keys have expiration policies. Generate a new key in Klaviyo and update it in On Belay → Integrations → Klaviyo → Update key. Consider creating a dedicated service account or machine user for On Belay so the key isn't tied to a personal account.
