Issue Summary

Trello Power-Up developers currently have no way to add Google Analytics 4 (GA4), Facebook Pixel, or other third-party tracking scripts to their Power-Up marketplace listing pages. This prevents developers from understanding how users discover and interact with their listings, making it impossible to measure the effectiveness of marketing campaigns, paid ads, or organic traffic channels driving visits to the listing.

Expected Results

Power-Up developers should be able to add a GA4 measurement ID (and optionally a Facebook Pixel or similar tracking script) to their listing page, similar to what is already available for Atlassian Marketplace app listings (via GA4 and Segment integrations). This would allow developers to track page views, traffic sources, and conversion events (such as installs) for their Power-Up listing.

Actual Results

There is no field or mechanism available for Trello Power-Up developers to add any third-party analytics or tracking to their marketplace listing. Analytics tracking is only possible inside the Power-Up iframe itself, not on the listing page.

Workaround

Developers can add GA4 tracking inside their Power-Up's own iframe pages to track in-Power-Up interactions, but this does not cover the marketplace listing page or traffic source attribution.
