This guide will walk you through the steps on creating a Shopify private app and ultimately retrieve the API credentials. We recommend opening a text editor to save the credentials that will be created, i.e. notepad or similar.
You will see the Admin API Permissions box which will say there are no active permissions. You will need to set Read Access to all permissions.
Click Show inactive Admin API Permissions
A dropdown list of permissions will appear.
Important: In the list of permissions, select Read Access for every permission. With only read access, nothing can be modified on your Shopify account.
