3. Anonymous Access

The following instructions detail how to allow anonymous access to your saved query API endpoint.

Navigate to the table your query will be referencing. In this example, it is the Accessibility Assessments table (Image 1).
Navigate to Data Controls > Entitlements.
On a new row, add in the Anonymous user and ensure that either "View All Comuns" (to expose all the data) or "View Selected Columns" (to select individual columns) is checked off (Image 1).

Clicking on inline images in Gitbook will open a larger version.

4. Design your query (Image 2). For more information on creating new saved queries, click here.

5. Once you have written your query, navigate to Design Query > Info, on the left navigation bar.

6. Change your API Result Format to JSON (Image 3).

7. Navigate to Design Controls from the left navigation bar.

8. To ensure that anonymous users have the correct permission needed to execute the query that generates the API response, add the "Anonymous" user to the users permission group uiunder "Who can execute this query?" (Image 4).

9. Navigate to "Execute Query" from the left navigation bar.

10. Copy your REST API endpoint URL (Image 5).

11. To confirm that anonymous access has been successfully set up, paste the URL into an incognito/private browser (Image 6).

3.1 Troubleshooting

401 errors likely mean you have not added the Anonymous user to the list of users (not "Groups") that can execute the query.
