Hi Community,

Hopefully you can help me as I don’t know what I am doing wrong and the support emails are not getting me anywhere fast.

Firstly our setup is the following:

  • Magento CE 2.3.3 (soon to be upgraded but current version)
  • Klaviyo 1.2.3 (the latest for this version of Magento)

Steps Taken:

  1. Downloaded the Klaviyo Plugin
  2. Installed the Plugin
  3. Activated the Plugin
  4. Created a User
  5. Created a Public/Secret Key
  6. Setup the configuration
  7. Gone to Klaviyo and put the configuration in.


“Unable to connect to your store, check your Username and Password / API key. “

I have tried using the User Credentials configured on the plugin as well as the API Key as password but nothing is working.

It is a pitty there is no phone support as I feel like I have missed something so simple and the correspondance going back and forth has now been over two weeks. Really need to sort this soon.

Any help would be appreciated.

From what I see it seems to me like you switched Public and Private API keys in your Magento. Public key is shorter and Private key is longer.. just switch their places and it should be ok I think
