Dynamic Event Property Reference Guide For Sonar-Powered Klaviyo Flows

Sonar Send events mirror Klaviyo’s standard schema—so product images, titles, prices, and links should render seamlessly in your Sonar-powered flows. This guide highlights the most common event types and properties to help you get started quickly.

Always validate in Klaviyo using Preview & Test → All properties, and when building dynamic content, copy variables directly from Klaviyo to ensure proper casing and syntax.

Use the below tables as a starting point to explore the properties that matter most to your flows. There is a single table per Sonar-metric we send to Klaviyo.

Wrapping Up

By aligning Sonar Send events with Klaviyo’s standard schema, you can confidently build dynamic flows that display the right content at the right time. To get the most from these properties, keep a few best practices in mind and lean on Klaviyo’s documentation when needed.

Troubleshooting

If a property doesn’t render, check Preview & test → All properties and copy the correct variable.
Use lookup syntax for keys with spaces: {{ event|lookup:'Product Name' }}.
For arrays (line_items), either reference specific indexes (0, 1, 2) or use a loop.
Wrap prices in {% currency_format … %} if they display as raw numbers.
Establish default values whenever possible using default:.
For deeper guidance, check out Klaviyo’s own resources that cover much of this in more detail.
- Message personalization reference – variable syntax, lookup, and currency formatting.
- Use event data to personalize flows – copy tags from Preview & Test.
- Build dynamic blocks – arrays, loops, and row collections.
