Klaviyo v2 (Edge)

Last updated on Sep 11, 2026

Klaviyo is a marketing automation platform used by consumer brands to manage email, SMS, and other messaging channels from a single account. It unifies customer and behavioral data so businesses can build personalized, cross-channel marketing campaigns and automated flows.

Hevo uses the Klaviyo REST APIs to replicate data from your Klaviyo account to the Destination of your choice. To ingest data, you must provide Hevo with a Private API key generated from your Klaviyo account that grants read access to your account’s data.

Handling of Deletes

Once every 7 days, Hevo compares the data fetched from the Source object with the data present in the Destination table. If a record exists in the Destination but is no longer returned by the Source, the record is marked as deleted by setting the value of the metadata column __hevo__marked_deleted to True. This applies to the following objects:

  • Campaign

  • Campaign List

  • Campaign Message

  • Campaign Message Send Time

  • Campaign Tracking UTM Param

  • Email Template

  • Flow

  • Global Exclusion

  • List

  • List Exclusion

  • List Person

  • Metric

  • Person

  • Segment

  • Segment Person

For all other objects, Hevo does not support capturing deletes.
