+## Customize Permissions
+
+Permissions determine what each role can access or modify within your workspace, including workspace objects records, settings, and actions.
+
+### Object Permissions
+
+Control access to records and fields:
+
+- Under **All Objects**, apply permissions like **See Record**, **Edit Records**, **Delete Records**, or **Destroy Records** to all objects
+- Under **Object-Level Permissions**, configure exceptions for individual objects. These override the settings from **All Objects**
+
+To override parent permissions and apply stricter rules:
+
+- Click **X** to remove the inherited rule
+- Select the specific permissions for the selected object 
+- Click the orange **Undo** icon (circular arrow) to revert changes
+
+When done, click **Finish**, then **Save** once redirected to the role page.
+
+### Workspace Settings Permissions
+
+Control access to workspace settings in two ways:
+
+- Toggle **Settings All Access** to grant full access 
+- Or enable specific permissions (e.g., API key generation, workspace preferences, role assignment, data model configuration, security settings, and workflow management)
+
+### Workspace Action Permissions
+
+Controll access to general workspace actions:
+
+- Toggle **Application All Access** to grant full permissions
+- Or enable individual actions such as **Send Email**, **Import CSV**, and **Export CSV**
