# Sending Party Invites

In order to access online features, the player must be logged in with the **Online Subsystem**. Please visit the [**Authentication**](/kronos-matchmaking/usage/authentication/authenticating-users.md) page for more information.

## Invite Players To The Party <a href="#classes" id="classes"></a>

There are two ways to invite players into a party.

### External Invite UI

This invite method uses the online platform's own invite UI (e.g. **Steam Overlay**) to send party invites. Simply use the `ShowPartyInviteUI` to make the external invite UI appear. This is the easiest, most convenient way of handling invites because this way you do not have to set up your own widgets and query friends list. When the user accepts the invite, they will join the party automatically.

{% tab title="C++" %}

```cpp
#include "KronosStatics.h"
```

```cpp
// Show the external invite UI for party sessions (e.g. Steam Overlay).
// Note that not all Online Subsystems support this.
UKronosStatics::ShowPartyInviteUI();
```

{% endtab %}
{% endtabs %}

### In-Game Party Invite

You can also use the `SendPartyInviteToFriend` function in `KronosStatics`. This function requires the friend's unique id. You can get a list of online friends via the `ReadUserFriendsList` node.

{% hint style="warning" %}
**NOTE:** The Steam Online Subsystem does not have the necessary callbacks registered for when an invite is received which means that an in-game "invite received" popup cannot be implemented currently. The invite must be accepted through the Steam Overlay.
