📝 About Stream

You can sign up for a Stream account at our Get Started page.

You can use this library to access chat API endpoints server-side.

For the client-side integrations (web and mobile) have a look at the JavaScript, iOS and Android SDK libraries (docs).

⚙️ Installation

$ composer require get-stream/stream-chat

✨ Getting started

require_once "./vendor/autoload.php";

Instantiate a new client, find your API keys in the dashboard.

$client = new GetStream\StreamChat\Client("<api-key>", "<api-secret>");

Generate a token for client-side usage

$token = $client->createToken("bob-1");

// with an expiration time
$expiration = (new DateTime())->getTimestamp() + 3600;
$token = $client->createToken("bob-1", $expiration);

Update / Create users

$bob = [
    'id' => 'bob-1',
    'role' => 'admin',
    'name' => 'Robert Tables',

$bob = $client->upsertUser($bob);

// Batch update is also supported
$jane = ['id' => 'jane', 'role' => 'admin'];
$june = ['id' => 'june', 'role' => 'user'];
$tom = ['id' => 'tom', 'role' => 'guest'];
$users = $client->upsertUsers([$jane, $june, $tom]);

Channel types

$channelConf = [
    'name' => 'livechat',
    'automod' => 'disabled',
    'commands' => ['ban'],
    'mutes' => true

$channelType = $client->createChannelType($channelConf);

$allChannelTypes =  $client->listChannelTypes();

Channels and messages

$channel = $client->Channel("messaging", "bob-and-jane");
$state = $channel->create("bob-1", ['bob-1', 'jane']);
$channel->addMembers(['mike', 'joe']);


$msg_bob = $channel->sendMessage(["text" => "Hi June!"], 'bob-1');

// Reply to a message
$reply_bob = $channel->sendMessage(["text" => "Long time no see!"], 'bob-1', $msg_bob['message']['id']);


$channel->sendReaction($reply_bob['message']['id'], ['type' => 'like'], 'june');



$channel->banUser('june', ["reason" => "Being a big jerk", "timeout" => 5, "user_id" => 'bob-1']);
$channel->unbanUser('june', ["user_id" => 'bob-1']);


$device_id = "iOS_Device_Token_123";
$client->addDevice($device_id, "apn", "june");
$devices = $client->getDevices('june');

$client->deleteDevice($device_id, 'june');

🙋‍♀️ Frequently asked questions

  • Q: What date formats does the backend accept?
  • A: We accept RFC3339 format. So you either use raw strings as date or you implement a serializer for your DateTime object.
class MyDateTime extends \DateTime implements \JsonSerializable
    public function jsonSerialize()
        // Note: this returns ISO8601
        // but it's compatible with 3339
       return $this->format("c");

$createdAt = new MyDateTime();

	['type' => "messaging"], 
	['created_at' => ['$lte' => $createdAt]], 
	['limit' => 10]
