Can’t integrate my Klaviyo account to contact 7

Hi,

Do you know how to integrate Klaviyo with contact 7 ?

I received an error message when I tried to put the API code.

In Contact 7 I went to >> Integration >> Sendinblue or Constant Contact.

I tried both of them, and that didn’t work. I create an API code in Klaviyo and put the API code in the same day I created it, and I received the error message.

Thank you.
