📝 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

stream-chat-ruby supports:

  • Ruby (2.7, 3.0, 3.1)
$ gem install stream-chat-ruby

✨ Getting started

require 'stream-chat'


💡 Note: since v2.21.0 we implemented Sorbet type checker. As of v2.x.x we only use it for static type checks and you won't notice any difference, but from v3.0.0 we will enable runtime checks 🚨 🚨 🚨.

What this means, is that you'll receive an error during runtime if you pass an invalid type to our methods. To prepare for that, just make sure whatever you pass in, matches the method signature (sig { ... }).

Update (2022-May-24): we have relased v3.0.0 with enabled runtime checks.

Additionally, in a future major version, we would like to enforce symbol hash keys during runtime to conform to Ruby best practises. It's a good idea to prepare your application for that.

# Wrong:
user = { "user" => { "id" => "bob-1"}}
# Correct:
user = { user: { id: "bob-1" }}

Generate a token for client-side usage:


Create/Update users

    id: 'bob-1',
    role: 'admin',
    name: 'Robert Tables'

# Batch update is also supported
jane = {id: 'jane-1'}
june = {id: 'june-1'}
client.upsert_users([jane, june])

Channel types

    name: 'livechat',
    automod: 'disabled',
    commands: ['ban'],
    mutes: true

channel_types = client.list_channel_types()


# Create a channel with members from the start
chan ="messaging", channel_id: "bob-and-jane", data: {:members => ['bob-1', 'jane-77']})

# Create a channel and then add members
chan ="messaging", channel_id: "bob-and-jane")
chan.add_members(['bob-1', 'jane-77'])


chan.send_reaction(m1['id'], {type: 'like'}, 'bob-1')



chan.ban_user('bob-1', timeout: 30)



m1 = chan.send_message({text: 'Hi Jane!'}, 'bob-1')

deleted_message = client.delete_message(m1['message']['id'])


jane_phone = client.add_device({:id => 'iOS Device Token', :push_provider => push_provider.apn, :user_id => 'jane-77'})


client.remove_device(jane_phone['id'], jane_phone['user_id'])


client.create_blocklist('my_blocker', %w[fudge cream sugar])

# Enable it on 'messaging' channel type
client.update_channel_type('messaging', blocklist: 'my_blocker', blocklist_behavior: 'block')



Export Channels

# Register an export
response = client.export_channels({type: 'messaging', id: 'jane'})

# Check completion
status_response = client.get_export_channel_status(response['task_id'])
# status_response['status'] == 'pending', 'completed'


# Create a user or channel segment
client.create_segment({ name: 'test', type: 'user', filter: { uniq: 'a flag on users' } })

# Create a campaign that uses the segment
    name: 'test',
    text: 'Hi',
    sender_id: campaign_sender,
    segment_id: segment_id,
    channel_type: 'messaging'

# Schedule the campaign

# Query the campaign to check the status
response = client.query_campaigns(filter_conditions: { id: campaign_id })
response['campaigns'][0]['status'] == 'completed'

# Read sent information
client.query_recipients(filter_conditions: { campaign_id: campaign_id })

Rate limits

# Get all rate limits
limits = client.get_rate_limits

# Get rate limits for specific platform(s)
limits = client.get_rate_limits(server_side: true)

# Get rate limits for specific platforms and endpoints
limits = client.get_rate_limits(android: true, ios: true, endpoints: ['QueryChannels', 'SendMessage'])
