I just took over as site manager for a eCommerce company. I have run into a few odd occurrences in getting onboarded here where settings in programs beyond Klaviyo were adjusted preventing them from working as intended. Klaviyo has been used for several years, but was not functioning when I started last week.
I was receiving error messages when trying to confirm the Integrations password / API Keys had been changed and after re-running the set up in Magento and receive the following error message:
We received a 401 authentication error. Please ensure your Magento server supports HMAC-SHA1 signatures for OAuth authentication and that your credentials are correct.
I’m not sure at this point were to look, or what additional settings were changed.
