gmda_sendFriendInvite

Sends a friend invitation to a player by key, with an optional message.

Asynchronous (result via event)

Signature

gmda_sendFriendInvite(player_key, [message]) -> real

What it does

POSTs /friends/invite. Returns 1 when the request is fired, 0 when there is no active session. The result arrives later as an invite_sent event: on success response.invitation is the created row { id, to_player_key, to_player_name, status, message, created_at, expires_at }. On failure success is false and error explains why (self-invite, already friends, a duplicate pending invite, the other player already invited you, that player is not accepting invitations, or not found).

Parameters

Name	Type	Default	Description
player_key	string	required	The target player's key (e.g. from a leaderboard row, search result, or profile).
message	string	""	Optional note attached to the invite (stripped of control chars and capped at 200 chars).

How to call it

Fire gmda_sendFriendInvite(), then read the invite_sent event from gmda_pollEvent() in your Step loop. Reverse-pending means they already invited you, so accept their pending invite instead of sending a new one.

Result event: invite_sent { success, response }

Example

gmda_sendFriendInvite(player_key, "Let's play!");

// In the Step event, drain results:
var _e = gmda_pollEvent();
while (!is_undefined(_e)) {
    if (_e.event == "invite_sent") {
        if (_e.success) show_debug_message("invited " + _e.response.invitation.to_player_name);
        else show_debug_message("invite failed: " + string(_e.error));
    }
    _e = gmda_pollEvent();
}

Use cases

Add-friend button on a player's profile.
Invite someone you saw on a leaderboard or in search results.
