When Klaviyo and Keap operate in isolation, customer engagement data often fails to sync properly. For instance, if a customer subscribes to a newsletter in Klaviyo, that information may not be reflected in Keap, leading to missed follow-up opportunities. The marketing team is forced to manually check Klaviyo for new subscribers and then input that data into Keap, wasting hours each week and risking human error in data entry.

Top Ways to Automate Klaviyo & Keap

  • Automated Lead Nurturing: Automatically sync leads from Keap to Klaviyo, triggering personalized email campaigns based on user behavior and engagement, ensuring timely follow-ups and improved conversion rates.
  • Real-Time Customer Insights: Integrate customer data between platforms to create a unified view of customer interactions, enabling targeted marketing strategies and data-driven decision-making.
  • Streamlined Campaign Performance Tracking: Automatically update campaign metrics in Keap based on Klaviyo email performance, allowing for comprehensive analysis and optimization of marketing efforts without manual intervention.

How to Build the Klaviyo → Keap Sync

  1. In Klaviyo, navigate to the 'Webhooks' section and create a new webhook. Set the trigger to activate on 'Subscribe to List'.
  2. Configure the webhook to send a POST request to your Keap endpoint: https://api.keap.com/crm/rest/v1/contacts. Ensure you include the necessary payload data such as email, first_name, and last_name from the Klaviyo subscriber data.
  3. In Keap, ensure your API is set up to accept the incoming data. Map the incoming fields from Klaviyo to the corresponding fields in Keap, ensuring that the email field is marked as unique to avoid duplicates.
  4. Test the integration by subscribing a test email in Klaviyo and verifying that the contact appears in Keap with the correct details.
  5. Monitor the webhook logs in Klaviyo to ensure successful POST requests to Keap and troubleshoot any errors that arise during the data transfer.

Developer Warnings & API Gotchas

  • Ensure that the email field in Keap is set to unique; otherwise, duplicate entries may occur if the same user subscribes multiple times.
  • Be cautious of the data types being sent; Klaviyo may send strings while Keap expects integers for certain fields, leading to failed API calls.
  • When mapping fields, verify that all required fields in Keap are included in the payload from Klaviyo; missing fields can result in incomplete contact records.
