## Update Group

*In other words, as a group owner, how can I update the group details?*

You can update the existing details of the group using the `updateGroup()` method.

<Tabs>
  <Tab title="JavaScript">
    ```javascript theme={null}
    var GUID = "GUID";
    var groupName = "Hello Group";
    var groupType = CometChat.GROUP_TYPE.PUBLIC;
    var group = new CometChat.Group(GUID, groupName, groupType);

    CometChat.updateGroup(group).then(
    group => {
      console.log("Groups details updated successfully:", group);
    }, error => {
      console.log("Group details update failed with exception:", error);
    }
    );
    ```
  </Tab>

  <Tab title="TypeScript">
    ```typescript theme={null}
    var GUID: string = "GUID";
    var groupName: string = "Hello Group!";
    var groupType: string = CometChat.GROUP_TYPE.PUBLIC;

    var group: CometChat.Group = new CometChat.Group(GUID, groupName, groupType);

    CometChat.updateGroup(group).then(
      (group: CometChat.Group) => {
          console.log("Group details updated successfully:", group);
      }, (error: CometChat.CometChatException) => {
          console.log("Group details update failed with exception:", error);
      }
    );
    ```
  </Tab>
</Tabs>

This method takes an instance of the `Group` class as a parameter which should contain the data that you wish to update.

| Parameter | Description                  |
| --------- | ---------------------------- |
| `group`   | an instance of class `Group` |

After a successful update of the group, you will receive an instance of `Group` class containing update information of the group.

<Accordion title="Response">
  **On Success** — `updateGroup()` returns the updated `Group` object:

## Best Practices

<AccordionGroup>
  <Accordion title="Set the GUID on the Group object">
    The `Group` object passed to `updateGroup()` must have the correct GUID set. Only the fields you set on the object will be updated — unset fields remain unchanged.
  </Accordion>

  <Accordion title="Only owners and admins can update groups">
    The `updateGroup()` method requires the logged-in user to be the owner or an admin of the group. Participants and moderators cannot update group details.
  </Accordion>
</AccordionGroup>

## Troubleshooting

<AccordionGroup>
  <Accordion title="Update fails with permission error">
    Verify the logged-in user is the owner or an admin of the group. Use `getGroup()` to check the user's scope in the group.
  </Accordion>

  <Accordion title="Group type not changing after update">
    The `type` field of a group is not editable after creation. To change a group's type, you would need to create a new group with the desired type.
  </Accordion>
</AccordionGroup>
