Magento: It says 'Session expired' or 'Cannot authorise to RESTful API access' when retrieving store view list

Issue

You create a Magento integrated app using the Quick Start Guide. In step 3 Configure Plugin, when you verify connection, you get the warning message 'Session expired' or 'Cannot authorise to RESTful API access'. As a result, the store view list is unable to be retrieved and you fail to create your app.


Cause

This issue happens because the setting Use SID on Frontend in Magento Admin is set to NO while it should be set to YES.

  3. Save changes.
