Klaviyo Integration

Step 1: Set up your Klaviyo API key with Buy Again & Reorder Reminder

You can manage your Klaviyo account’s API keys from your account settings.

1: Create API keys

• Click your account name in the bottom left and then click on Settings.
• Click on API keys tab and Click on Create Private API Key.

Note

Make sure to copy and store private key securely just like your password. Once a private API key is created, it cannot be viewed again.

• Choose Full access key option in the ‘Select access level’ section.
• Name the API key and click on Create.

We recommend saving the API key with ‘Buy Again & Reorder Reminders Key’ so that it becomes clear that this key is used by Buy Again & Reorder Reminders App.

2: Review double Opt-In Settings

• Double Opt-In Enabled: If you’ve enabled double opt-in, customers who agree to marketing consent will receive a confirmation message via Email or SMS from Klaviyo. They must confirm their subscription before a new profile is synced to Klaviyo, along with subscription to SMS or Email & SMS reorder reminders channels.
• Double Opt-In Disabled: If you disable double opt-in, customers will not need to confirm their subscription. In this case, customer data will be synced to Klaviyo without explicit confirmation.

For more details and to adjust your settings, review the double opt-in settings in your Klaviyo account.

Our Recommendation

We recommend disabling the double opt-in setting if you wish to get the customer data synced instantly

Make sure to review the double opt-in settings.

3: Integrate Klaviyo with Buy Again & Reorder Reminder

To enable reorder reminders, copy the Klaviyo API key that you created above and paste it in Buy Again & Reorder Reminder app’s Reorder reminders settings.
