I am currently developing a Shopify App and at the moment, it only makes use of the Storefront API. I want my app to also make modifications to the Admin Area, specifically in a similar way that the Metafield Guru App adds a tab at product level, and allows you to go into the metafields of a certain product and make changes to them.
Metafields Guru App Tab at Product Level in Admin Area
I was hoping someone could point me in the right direction for this, as I am trying to create a similar feature in which the user can access other properties for the productt.
Thank you
This option is configured in the Shopify Partner account for the APP.
There is option where you can create Admin Links when you install the App. It's not code related, it's just Shopify feature for Apps. More info in here: https://shopify.dev/tutorials/add-an-admin-link-to-the-shopify-admin-with-app-extensions
There is no other way to modify the admin area (with code) since Shopify back-end is a closed platform and you don't have access to modify it.
