Hi everyone,
I need some clarification regarding the upcoming change where Shopify will stop allowing new Legacy Custom Apps after January 1, 2026.

My current workflow:
I ask my clients (Shopify merchants) to:

  1. Go to Settings → Apps and sales channels → Develop apps

  2. Create a Custom App (Legacy Custom App)

  3. Enable API scopes like read_products

  4. Install the app

  5. Copy the Admin API access token and share it with me

  6. I then use this token to call the Admin API and fetch their store products

This method works well today.

  1. For new clients after 2026, can I still ask them to use the same approach?

    • Or will the ability to create a custom app from the store admin be completely removed?

    • Will merchants still get access tokens this way?

  2. If this method won’t work for new clients after 2026,
    what is the recommended future-proof approach?

You’ll need to create the app through the new dev dashboard, and use something like Using the client credentials grant

If you are a partner creating a client transfer store that is going to be transferred to a merchant you are still able to create custom apps in the admin before you transfer the store. After the store is transferred you will must create apps for that merchant organization using the dev dashboard.

With the new access with Token, it’s possibile use REST API ADMIN ? or only GRAPH-QL ?
