I’ve been trying to fix my n8n workflow, but it’s asking for an API key that starts with KLV. 
When I generate a new key in Klaviyo, it only gives me one that starts with pk_—not KLV. Anyone else run into this?? Not sure what I’m missing here…
Hey @Renzel_Baltazar hope all is well, welcome to the community.
Would you like to expand on you question? Which node are you using? Can you show an error you are getting on a screenshot?
I am not sure why you have the impression about KLV
It can use the private key start with pk_ and working normally
change the key in here
Klaviyo-API-Key pk_{private_key}
Replace pk_{private_key} to your private key and remain the Klaviyo-API-Key at the begining.
