  description: 'The Instant Tests API operations lets you create and run new instant tests. You will need to be an Account Admin.


    The response does not include the immediate test results. Use the Test Results endpoints to get test results after creating and executing an instant test. You can find the URLs for these endpoints in the _links section of the test definition that is returned when you create the instant test.
