The account settings section in Umbraco is where you'll need to specify the user credentials that will be used to connect to your GatherContent account via the API. You have to set all these parameters in order to start:
Select "GatherContent" and "Account Settings"
Select "GatherContent" in your left-hand menu. Then select "Account Settings".
Enter Credentials
Enter your GatherContent GatherContent User Email Address, API Key, Output Date format, Import Date format, Platform URL and click "Save Credentials". You can get instructions on generating your API Key in our help docs.
All dates in the plug-in will be displayed in the specified format. If not set, ‘dd/mm/yyyy hh:mm tt’ format will be used by default.
