Creating the Private API Key in Shopify
It only takes a few steps to generate the Private API Key. First, access the Apps section in your Shopify Admin page. From there you will scroll all the way down to the bottom of the page. You will see the “Manage private apps” link under the Recommended Apps section.
Clicking this link will open the “Private Apps” page in Shopify. If this is the first time you’ve visited this section, then Shopify will prompt you to enable and accept the terms before you can create a new API Key. Once you’ve enabled the access, you can click on the “Create new private app” button. This will then bring-up the “Private App” details form where you must configure the basic settings of the app. It’s best to only configure the minimum required access scopes as required for the integration. Granting too much permission opens the door to potential data theft if the API Keys ever fall into the wrong hands.
