Invites

Invites allow you to add users to a channel with a pending state. The invited user receives a notification and can accept or reject the invite.

Unread counts are not incremented for channels with a pending invite.

Invite Users

val channelClient = client.channel("messaging", "general")

channelClient.inviteMembers(memberIds = listOf("nick")).enqueue { result ->
  if (result is Result.Success) {
    val channel: Channel = result.value
  } else {
    // Handle Result.Failure
  }
}

use GetStream\ChatClient;
use GetStream\GeneratedModels as Models;

$client = new ChatClient("{{ api_key }}", "{{ api_secret }}");

$client->updateChannel("messaging", "team-chat-5", new Models\UpdateChannelRequest(
    invites: [new Models\ChannelMemberRequest(userID: "thierry")],
));

await channel.inviteMembers(['nick']);

import StreamChat

let controller = client.channelController(for: .init(type: .messaging, id: "general"))

// Controllers

controller.inviteMembers(userIds: ["thierry"])

// State layer (async-await)

try await chat.inviteMembers(["thierry"])

require 'getstream_ruby'

Models = GetStream::Generated::Models

client.chat.update_channel("messaging", "general", Models::UpdateChannelRequest.new(
  invites: [Models::ChannelMemberRequest.new(user_id: 'thierry')]
))

using GetStream;
using GetStream.Models;

var client = new StreamClient("{{ api_key }}", "{{ api_secret }}");
var chat = new ChatClient(client);

var channelId = "channel-id";

// Send invites
await chat.UpdateChannelAsync("messaging", channelId,
    new UpdateChannelRequest
    {
        Invites = new List<ChannelMemberRequest>
        {
            new ChannelMemberRequest { UserID = "thierry" }
        }
    });

// Android SDK
ChannelClient channelClient = client.channel("messaging", "general");

List<String> memberIds = Arrays.asList("thierry", "tommaso");
Map<String, Object> data = new HashMap<>();
data.put("invites", Arrays.asList("nick"));

channelClient.create(memberIds, data).enqueue(result -> {
  if (result.isSuccess()) {
    Channel channel = result.data();
  } else {
    // Handle result.error()
  }
 });


// Backend SDK
chat.updateChannel("messaging", "general", UpdateChannelRequest.builder()
    .invites(List.of(
        ChannelMemberRequest.builder().userID("thierry").build(),
        ChannelMemberRequest.builder().userID("tommaso").build()))
    .build()).execute();

Accept an Invite

Call acceptInvite to accept a pending invite. You can optionally include a message parameter to post a system message when the user joins (e.g., "Nick joined this channel!").

channelClient.acceptInvite(
  message = "Nick joined this channel!"
).enqueue { result ->
  if (result is Result.Success) {
    val channel: Channel = result.value
  } else {
    // Handle Result.Failure
  }
}

// initialize the channel
const channel = client.channel("messaging", "awesome-chat");

// accept the invite
await channel.acceptInvite({
  message: { text: "Nick joined this channel!" },
});

// accept the invite server side
await channel.acceptInvite({ user_id: "nick" });

// Initialize the channel
final channel = client.channel('messaging', id: 'awesome-chat');
await channel.watch();

// Accept the invite
await channel.acceptInvite();

// Or with a system message
await channel.acceptInvite(Message(text: 'Nick joined this channel!'));

import StreamChat

let controller = client.channelController(for: .init(type: .messaging, id: "general"))

// Controllers

controller.acceptInvite(message: "Nick joined this channel!")

// State layer (async-await)

try await chat.acceptInvite(with: "Nick joined this channel!")

using GetStream;
using GetStream.Models;

var client = new StreamClient("{{ api_key }}", "{{ api_secret }}");
var chat = new ChatClient(client);

var channelId = "channel-id";

// Accept invite
await chat.UpdateChannelAsync("messaging", channelId,
    new UpdateChannelRequest
    {
        AcceptInvite = true,
        UserID = "thierry"
    });

// Android SDK
channelClient.acceptInvite("Nick joined this channel!").enqueue(result -> {
  if (result.isSuccess()) {
    Channel channel = result.data();
  } else {
    // Handle result.error()
  }
});

// Backend SDK
chat.updateChannel("messaging", "general", UpdateChannelRequest.builder()
    .acceptInvite(true)
    .userID("nick")
    .message(MessageRequest.builder().text("Nick joined the channel").userID("nick").build())
    .build()).execute();

Reject an Invite

Call rejectInvite to decline a pending invite. Client-side calls use the currently connected user. Server-side calls require a user_id parameter.

await channel.rejectInvite();

import StreamChat

let controller = client.channelController(for: .init(type: .messaging, id: "general"))

// Controllers

controller.rejectInvite()

// State layer (async-await)

try await chat.rejectInvite()

using GetStream;
using GetStream.Models;

var client = new StreamClient("{{ api_key }}", "{{ api_secret }}");
var chat = new ChatClient(client);

var channelId = "channel-id";

// Reject invite
await chat.UpdateChannelAsync("messaging", channelId,
    new UpdateChannelRequest
    {
        RejectInvite = true,
        UserID = "thierry"
    });

// Android SDK
channelClient.rejectInvite().enqueue(result -> {
  if (result.isSuccess()) {
    // Invite rejected
  } else {
    // Handle result.error()
  }
});

// Backend SDK
chat.updateChannel("messaging", "general", UpdateChannelRequest.builder()
    .rejectInvite(true)
    .userID("nick")
    .build()).execute();

Query Invites by Status

Use queryChannels with the invite filter to retrieve channels based on invite status. Valid values are pending, accepted, and rejected.

Query Accepted Invites

val request = QueryChannelsRequest(
  filter = Filters.eq("invite", "accepted"),
  offset = 0,
  limit = 10
)
client.queryChannels(request).enqueue { result ->
  if (result is Result.Success) {
    val channels: List<Channel> = result.value
  } else {
    // Handle Result.Failure
  }
}

const invites = await client.queryChannels({
  invite: "accepted",
});

//server side (query invites for user rob)
const invites = await client.queryChannels(
  {
    invite: "accepted",
  },
  {},
  { user_id: "rob" },
);

final invites = await client.queryChannels(filter: Filter.equal('invite', 'accepted'));

import StreamChat

let controller = chatClient.channelListController(
  query: .init(
    filter: .equal(.invite, to: .accepted)
  )
)

controller.synchronize { error in
  if let error = error {
    // handle error
    print(error)
  } else {
    // access channels
    print(controller.channels)

    // load more if needed
    controller.loadNextChannels(limit: 10) { _ in

const rejected = client.queryChannels({

//server side (query invites for user rob)
const invites = await client.queryChannels(

    invite: "rejected",

final rejected = await client.queryChannels(filter: Filter.equal('invite', 'rejected'));
