How to display the modal automatically on thankyou page

Shopify Apps

Topic summary

A developer is building a Checkout UI extension for Shopify and needs to display a modal/popup automatically on the Thank You page, rather than requiring user interaction like a button click.

Current Challenge:

  • Modals in Checkout UI extensions currently only trigger through user actions
  • The developer wants automatic display upon page load

Attempted Solutions:

  • Referenced a Shopify community thread indicating the Shopify team is actively working on this functionality
  • Web pixels were suggested but don’t work for this use case

Status: The discussion remains open with the developer seeking alternative approaches, as native auto-trigger functionality appears unavailable in the current Checkout UI extension framework.

Hi

I hope this message finds you well.

I am currently working on building a Checkout UI extension to implement a custom feature for a Shopify store. However, I am encountering a challenge when attempting to display a popup on the Thank You page.

The issue is that the popup or modal only appears when triggered by a button click or a similar user interaction. My objective is to have the popup display automatically upon reaching the Thank You page.

I would greatly appreciate your advice on whether this is feasible using the Checkout UI extension. If not, I would welcome any suggestions on alternative approaches to achieve the desired functionality.

Thank you in advance for your assistance.
