+title: "Manage User Permissions for Content"
+execute: 
+  eval: false
+---
+
+## Description 
+
+This recipe shows how to manage user permissions for a content item. This includes granting and revoking user access as either viewers or collaborators.
+
+This may be useful following the successful deployment of a content item where, by default, only the publisher has permission to view or change the content. It can also be helpful to revoke access if a user is no longer working on the project.
+
+## Output
+
+There is no generated output from this recipe, however the permissions for the specified content item are updated on the Connect server.
+
+## Workflow
+
+Four independent code samples are provided below:
+
+1. How to [grant a user access](#recipe-grant-a-user-access-to-a-content-item) to a content item.
+
+2. How to [revoke a users access](#recipe-revoke-a-users-access-from-a-content-item) from a content item.
+
+3. How to [grant a group access](#recipe-grant-a-group-access-to-a-content-item) to a content item.
+
+4. How to [revoke a groups access](#recipe-revoke-a-groups-access-from-a-content-item) from a content item.
+
+## Recipe: Grant a user access to a content item
+
+In this example, we grant a user access to a content item.
+
+This receipe requires the following inputs:
+
+1. The `content_guid` for the content item from which you want to add permissions.
+2. The `user_guid` for the user being granted access.
+3. The `access_type` which determines the type of permissions the user will receive. Valid values are "viewer" and "owner" (collaborator).

+## Recipe: Grant a group access to a content item
+
+In this example, we grant a group access to a content item.
+
+This receipe requires the following inputs:

+1. The `content_guid` for the content item from which you want to add permissions.
+2. Either the `group_guid` or `group_name` for the group being granted access. The `group_name` will be used if `group_guid` is blank.
+3. The `access_type` which determines the type of permissions the group will receive. Valid values are "viewer" and "owner" (collaborator).
