Need Help Retrieving Shopify App Extension UUID

Shopify Apps

Topic summary

A developer is trying to create a deep link to automatically add a Shopify app extension in the theme editor. According to Shopify documentation, this requires a SHOPIFY_EXTENSION_NAME_ID (also called app_embed_uuid) that should be retrievable from the .env file.

Problem encountered:

  • Running npm run shopify app env show (Shopify CLI v3) only displays API key, secret, and scopes—not the extension UUID
  • Inspecting the extension in the editor and searching for &app_embed_uuid also yielded no results

Current status:

  • The extension has been deployed
  • A cross-post was made to the Shopify Community forums seeking solutions
  • One commenter attempted to access the community forum link but encountered a loading error
  • No solution has been provided yet; the question remains unanswered

Hi everyone,

I’m working on a Shopify app extension, and my goal is to create a deep link that takes users directly to the editor page while automatically adding the app extension.
According to the Shopify docs, there is this part of the deep link called SHOPIFY_EXTENSION_NAME_ID, which as per docs could be retrieved from the .env file. [Link for this doc]

I have already deployed the extension and executed npm run shopify app env show. However, I couldn’t find the SHOPIFY_EXTENSION_NAME_ID in the output. The only details shown were API key, API secret, and scopes.

Just to provide some context, I am using Shopify CLI version 3.
Could someone guide me on how to obtain the SHOPIFY_EXTENSION_NAME_ID for my Shopify app extension?

P.S.

I have also attempted an alternative solution by inspecting the app extension in the editor and searching for &app_embed_uuid, but i couldn’t find it.

Thanks in advance!
