The User Management API allows you to manage user accounts from HTTP endpoints. To manage users, you must have the administrator role or your role must have been assigned the manage users and roles capability. For more information, see Manage Users.
Refer to Getting Started for Sumo Logic API Authentication, Endpoints, and Security.
Sumo Logic has several deployment types, which vary by geographic location and the date an account is created. Select the documentation link below that corresponds to your deployment. If you're not sure, see How to determine your endpoint.
