  • The role name must match one of the roles defined by GET:site/roles.
  • External groups may not be renamed

C# Sample: Modify a Group's Role

The following code example updates group with ID 2 to have the Contributor role:

Sample Code

Plug p = Plug.New("http://deki-hayes/@api/deki");
p.At("users", "authenticate").WithCredentials("admin", "password").Get();
XDoc groupDoc = new XDoc("group")
        .Elem("role", "Contributor")
p.At("groups", "2").Put(groupDoc);

Sample Response from executing Code

<group id="2" href="http://deki-hayes/@api/deki/groups/2">
    <name>My Contributors Group</name> 
    <service.authentication id="1" href="http://deki-hayes/@api/deki/site/services/1" /> 
    <users count="2" href="http://deki-hayes/@api/deki/groups/2/users" /> 
        <role id="4" href="http://deki-hayes/@api/deki/site/roles/4">Contributor</role>

Curl Sample: Modify a Group's Role

The following command sets a group's (group ID = 1) role to the one listed in "grouprole.xml".

Sample Code

curl -u admin:password -H "Content-Type: application/xml" -T grouprole.xml -i http://192.l68.168.110/@api/deki/groups/1

Implementation notes 

curl flags

Basic HTTP authentication. Sends a username and password to server so it can verify whether a user is of privilege to perform specific operation.
Adds a header or modifies an existing one. In this case, since an xml document is being sent, the content type must be set to "application/xml". The server will not accept the request otherwise.
-T file
Specifies a PUT request and XML document that contains the user data.
Includes the HTTP response header in the output. Useful for debugging.


ADMIN permission is required to execute above command. Otherwise, a 403 HTTP response (Forbidden) will be returned.
