New Requirements for Allowing Guest Community Users to Log a Case

To ensure your guest community users can securely log cases directly through contact support, enable Guest Access to the Support API and add NewCase to the quick actions.
  1. From Setup, enter Communities in the Quick Find box, then select All Communities.
  2. Select Manage next to the community you want your guest users to log cases via contact support.
  3. On the left-hand panel, click Administration.
  4. Click Pages.
  5. Click Go to
    Administration area of Community Management
  6. On the Sites Detail page, click Edit.
  7. Enable Guest Access to the Support API.
  8. Add NewCase, or a custom quick action to add cases, to the Selected Quick Actions.
  9. Click Save.


You must take these steps on each community you have guest users enabled. It isn’t global across all communities.
