If you wish to connect Notify Me! to Klaviyo, you will need both private and public API keys from your Klaviyo account.
Here are the steps to find them:
To find this you need to log in to your Klaviyo account.
On the top right corner, you should click on your shop name.
Select "Account".
Under Setting, you'll see the API keys option.
By selecting it, you can see the public and private API keys.
If you do not see a private key, don't worry! Simply click on "Create Private API Key" to generate one.
And voila! You have now successfully retrieved your Klaviyo API keys for the integration with Notify Me!."
