Query parameter passthrough takes the query string (search parameters) from the current URL the display is appearing on and appends it to the associated link.

This is useful for tracking campaigns and referrals across your site.

In the Link section of an image, button, or sticker component, check the "Query param passthrough" checkbox.

Example 1: Campaign tracking
A user lands on https: //yoursite.com/campaign?utm_source=google&utm_campaign=mycampaign and clicks on a popup link to https: //yoursite.com/product

Enabling query parameter passthrough will result in a final link with parameters https: //yoursite.com/product?utm_source=google&utm_campaign=mycampaign

​Example 2: Referral tracking
A user follows a referral link https: //yoursite.com/?referrer=yourfriend and clicks on a registration popup link to https: //yoursite.com/register
​

Without query parameter passthrough the referrer data for registration would be lost.

Enabling query parameter passthrough results in a final link with parameters preserved https: //yoursite.com/register?referrer=yourfriend
