# Groups and Permissions ## Roles, Groups & Method-Level Permissions Users can be organized into groups (e.g., admin group with full rights, read-only groups, groups with limited write access). Permissions are managed at the method level: individual methods can be made visible or invisible to specific users or user groups via the "Manage Methods" function. Example permission scenario: some users can view and add data but cannot delete objects. External users may not have permission to modify shipped system data types — `System > System Configuration > Data Types` is effectively read-only for external users. Custom data type creation (`System > Data Types > New Data Type`) is available to users even when modifying existing system data types is restricted. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
