Pinned messages

Pinned messages allow users to highlight important messages, make announcements, or temporarily promote content. Pinning a message is, by default, restricted to certain user roles, but this is flexible. Each channel can have multiple pinned messages and these can be created or updated with or without an expiration.

Pin and unpin a message

An existing message can be updated to be pinned or unpinned by using the .pinMessage and .unpinMessage methods. Or a new message can be pinned when it is sent by setting the pinned and pin_expires fields when using channel.sendMessage.

// Create pinned message
val pinExpirationDate = Calendar.getInstance().apply { set(2077, 1, 1) }.time
val message = Message(
  text = "Hey punk",
  pinned = true,
  pinExpires = pinExpirationDate
)

channel.sendMessage(message).enqueue { /* ... */ }

// Unpin message
channel.unpinMessage(message).enqueue { /* ... */ }

// Pin message for 120 seconds
channel.pinMessage(message, timeout = 120).enqueue { /* ... */ }

// Change message expiration to 2077
channel.pinMessage(message, expirationDate = pinExpirationDate).enqueue { /* ... */ }

// Remove expiration date from pinned message
channel.pinMessage(message, expirationDate = null).enqueue { /* ... */ }

// create pinned message
const { message } = await channel.sendMessage({
  text: "my message",
  pinned: true,
  pin_expires: "2077-01-01T00:00:00Z",
});

// unpin message
await client.unpinMessage(message);

// pin message for 120 seconds
await client.pinMessage(message, 120);

// change message expiration to 2077
await client.pinMessage(message, "2077-01-01T00:00:00Z");

// remove expiration date from pinned message
await client.pinMessage(message, null);

// create pinned message
final message = await channel
  .sendMessage(Message(
   text: 'my message',
   pinned: true,
   pinExpires: DateTime.now().add(Duration(days: 3)),
  ))
  .then((resp) => resp.message);

// unpin message
await channel.unpinMessage(message);

// pin message for 120 seconds
await channel.pinMessage(message, 120);

// change message expiration to 2077
await channel.pinMessage(message, DateTime(2077));

// remove expiration date from pinned message
await channel.pinMessage(message, null);

let messageController = client.messageController(cid: .init(type: .messaging, id: "general"), messageId: "message-id")

// Pin message for 120 seconds
messageController.pin(.expirationTime(120))

// Unpin message
messageController.unpin()

// Pin message to specific date
messageController.pin(.expirationDate(Date()))

name	type	description	default	optional
pinned	boolean	Indicates whether the message is pinned or not	false	✓
pinned_at	string	Date when the message got pinned	-	✓
pin_expires	string	Date when the message pin expires. An empty value means that message does not expire	null	✓
pinned_by	User	The user that pinned the message	-	✓

To pin the message user has to have PinMessage permission. You can find the list of permissions and defaults in Permission Resources and Default Permissions sections

Retrieve pinned messages

You can easily retrieve the last 10 pinned messages from the channel.pinned_messages field:

channelClient.query(QueryChannelRequest()).enqueue { result ->
  if (result.isSuccess) {
    val pinnedMessages: List<Message> = result.data().pinnedMessages
  } else {
    // Handle result.error()
  }
}

// get channel state
const channelState = await client.channel("messaging", channelId).query();
// get pinned messages from it
const pinnedMessages = channelState.pinned_messages;

// get channel state
final channelState = await channel.query();

// get pinned messages from it
final pinnedMessages = channelState.pinnedMessages;

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

channelController.synchronize() { error in
  if error == nil {
    channelController.channel?.pinnedMessages
  }
}

// Not yet supported in the Unreal SDK

$response = $channel->query([
      "watch" => false,
      "state" => false,
      "presence" => false
    ]);
$pinnedMessages = $response["pinned_messages"]

channel_state = channel.query(watch=False, state=False, presence=False)

pinned_message = channel_state["pinned_messages"]

channel_state = channel.query(watch: false, state: false, presence: false)

pinned_message = channel_state['pinned_messages']

_, err = channel.Query(ctx, map[string]interface{}{"watch": false, "state": true})
msgs := channel.PinnedMessages

var currentChannelState = await _channelClient.GetOrCreateAsync(_channel.Type, _channel.Id, new ChannelGetRequest
{
  State = true,
  Watch = false,
});

var pinnedMessags = currentChannelState.PinnedMessages;

// Will be implemented soon, raise a GitHub issue if you need this feature https://github.com/GetStream/stream-chat-unity/issues/

// Android SDK
channelClient.query(new QueryChannelRequest()).enqueue(result -> {
  if (result.isSuccess()) {
    List<Message> pinnedMessages = result.data().getPinnedMessages();
  } else {
    // Handle result.error()
  }
});

// Backend SDK
ChannelGetResponse resp = Channel.getOrCreate("type", "id").request();
List<Message> messages = resp.getPinnedMessages();

Paginate over all pinned messages

Stream Chat also provides dedicated endpoint for pinned messages of the channel which can be used to retrieve all pinned messages page by page:

// List the first page of pinned messages, pinned before now, of the channel with descending direction (newest on top)
channelClient.getPinnedMessages(
  limit = 10,
  sort = QuerySortByField.descByName("pinnedAt"),
  pagination = PinnedMessagesPagination.BeforeDate(
    date = Date(),
    inclusive = false,
  ),
).enqueue { result ->
  if (result.isSuccess) {
    val pinnedMessages: List<Message> = result.data()
  } else {
    // Handle result.error()
  }
}

// You can use a pinnedAt date retrieved from the previous request to get the next page
val nextDate = Date()
// List the next page of pinned messages
channelClient.getPinnedMessages(
  limit = 10,
  sort = QuerySortByField.descByName("pinnedAt"),
  pagination = PinnedMessagesPagination.BeforeDate(
    date = nextDate,
    inclusive = false,
  ),
).enqueue { result ->
  if (result.isSuccess) {
    val pinnedMessages: List<Message> = result.data()
  } else {
    // Handle result.error()
  }
}

// list first page of pinned messages of the channel with descending direction (newest on top)
const descPage1 = await channel.getPinnedMessages(
  { limit: 10 },
  { pinned_at: -1 },
);
const descLastMsg = descPage1.messages[descPage1.messages.length - 1];
// list next page of pinned messages
const descPage2 = await channel.getPinnedMessages(
  {
    limit: 10,
    id_lt: descLastMsg.id,
  },
  { pinned_at: -1 },
);

// list first page of pinned messages of the channel with ascending direction (oldest on top)
const ascPage1 = await channel.getPinnedMessages({ limit: 10 });
const ascLastMsg = ascPage1.messages[ascPage1.messages.length - 1];
// list next page of pinned messages with ascending direction
const ascPage2 = await channel.getPinnedMessages({
  limit: 10,
  id_gt: ascLastMsg.id,
});

    .enqueue(result -> {
      if (result.isSuccess()) {
        List<Message> pinnedMessages = result.data();
      } else {
        // Handle result.error()
      }
    });


// Backend SDK

  .request();

channelController.loadPinnedMessages(
  pageSize: 10,
  sorting: [.init(key: .pinnedAt, isAscending: false)],
  pagination: .earlier(Date(), inclusive: true)) { result in
    switch result {
    case .success(let pinnedMessages):
      print(pinnedMessages)
    case .failure(let failure):
      // …
