# Set assignee

Use the Set assignee operation to set an assignee for one or more of actions.

## Operation parameters

Note
For the purpose of setting an assignee for the selected actions, the following fields should be set as follows:

- **Credentials to connect with**: The `Client ID` and `Client Secret` of any application in your tenant. Retrieve the credentials from any application in your tenant (available in the [application settings](https://portal.transmitsecurity.io/applications/)). These credentials are not scoped to a specific app—they grant access to the entire tenant. Once saved, the credentials are stored as a `Mosaic account` and can be updated at any time.
- **Resource**: `Detection and Response`
- **Operation**: `Create list`


- **Action IDs**: Specifies one or more action IDs to assign to the assignee.
- **Assignee**: Specifies the email of the user to assign the actions to.


## Result

As the Transmit node is run, the following data is returned:

- `success`: Defines if the operation was successful.
- `affectedActionsCount	`: Specifies the number of assigned actions.
