# Construct XML to Update Access Control Lists

To update the Access Control Lists of items in OneDrive, you must construct some XML that specifies the identifiers of the items to update, and provides information about how to change the ACL.

    <identifiersXML>
        <identifier value="...">
            <acl_update>
                ...
            </acl_update>
        </identifier>
    </identifiersXML>

In the identifier `value` attribute, replace "..." with the document identifier of the item that you want to update. A document identifier can be found in the `AUTN_IDENTIFIER` field of an indexed document.

You can update the ACLs of several items by including more than one `identifier` element in your XML:

    <identifiersXML>
        <identifier value="...">
            <acl_update>
                ...
            </acl_update>
        </identifier>
        <identifier value="...">
            <acl_update>
                ...
            </acl_update>
        </identifier>
    </identifiersXML>

The following table describes the XML elements that you can use in the `acl_update` element to specify how to change the ACL.

XML Element | Description | Permitted Occurrences
--- | --- | ---
`<ace action="...">` | Add or remove an entry from the ACL. The `action` attribute must be specified and accepts the value `add` or `remove`. The following child elements must all appear exactly once: `principal` - the user or group whose permissions you want to modify in the ACL. The value you set must correspond to `principalType`. `principalType` - the type of principal specified by the `principal` element: `Email` - an e-mail address. `UserId` - a user ID. `level` - a comma-separated list of permissions to add or remove: `read` `write` `*` - allowed only when removing permissions. NOTE: To grant a user `write` permission, the user must already have `read` permission. If this is not the case, you must grant both `read` and `write`. | 0 or more

The following example demonstrates how to change the ACL for an item in OneDrive. It makes the following changes:

- removes all permissions from `someuser@mydomain.com`
- grants read and write permissions to `otheruser@mydomain.com`
- grants read permission to the user with ID `123456ABCD`

    <identifiersXML>
        <identifier value="BASE64IDENTIFIER==">
            <acl_update>
                <ace action="remove">
                    <principal>someuser@mydomain.com</principal>
                    <principalType>Email</principalType>
                    <level>*</level>
                </ace>
                <ace action="add">
                    <principal>otheruser@mydomain.com</principal>
                    <principalType>Email</principalType>
                    <level>read,write</level>
                </ace>
                <ace action="add">
                    <principal>123456ABCD</principal>
                    <principalType>UserId</principalType>
                    <level>read</level>
                </ace>
            </acl_update>
        </identifier>
    </identifiersXML>
