What is Extension Data?

Extension Data is a feature that allows you to attach additional data to user interaction events. This data will be passed along to your tag manager integrations.

How to use Extension Data?

There are a number of ways to use Extension Data.

1. Extension Data from URL query parameters

Format:

https://{url}/?komo_e:{unique key of extension data}={value}

Examples:

• Single string value: https://myhub.komo.site/?komo_e:custom_unique_id=ABC123
• JSON object: https://myhub.komo.site/?komo_e:custom_data={"some_id":"ABC123","some_measure":123456}

Extension data will be cleared when the session ends.

These komo_e:* values are not duplicated in eventData.queryString or eventData.url; they appear only on the sibling extensionData object.

2. Browser EmbedSDK

Once the setup script is loaded, you will be able to use the helper methods on the komoEmbed javascript object to set extension data. See the instructions here for more information.

3. React Native
