Ruby

Build and run Kiket extensions with a batteries-included, strongly-typed Ruby toolkit.

Features

🔌 Webhook decorators – define handlers with sdk.webhook("case.created", version: "v1").
🔐 Transparent authentication – HMAC verification for inbound payloads, workspace-token client for outbound calls.
🔑 Secret manager – list, fetch, rotate, and delete extension secrets stored in Google Secret Manager.
🌐 Built-in Sinatra app – serve extension webhooks locally or in production without extra wiring.
🔁 Version-aware routing – register multiple handlers per event and propagate version headers on outbound calls.
📦 Manifest-aware defaults – automatically loads extension.yaml/manifest.yaml, applies configuration defaults, and hydrates secrets from KIKET_SECRET_* environment variables.
📇 Custom data helper – call /api/v1/ext/custom_data/... with context[:endpoints].custom_data(project_id) using the configured extension API key.
📉 Rate-limit helper – inspect /api/v1/ext/rate_limit before launching heavy automation bursts.
🧱 Typed & documented – designed for Ruby 3.2+ with rich documentation.
📊 Telemetry & feedback hooks – capture handler duration/success metrics automatically.

Quickstart

gem install kiket-sdk

# main.rb
require 'kiket_sdk'

sdk = KiketSDK.new(
  webhook_secret: 'sh_123',
  workspace_token: 'wk_test',
  extension_id: 'com.example.marketing',
  extension_version: '1.0.0'
)

# Register webhook handler (v1)
sdk.register('case.created', version: 'v1') do |payload, context|
  summary = payload['case']['title']
  puts "Event version: #{context[:event_version]}"

  context[:endpoints].log_event('case.created', summary: summary)
  context[:secrets].set('WEBHOOK_TOKEN', 'abc123')

  { ok: true }
end

# Register webhook handler (v2)
sdk.register('case.created', version: 'v2') do |payload, context|
  summary = payload['case']['title']

  context[:endpoints].log_event('case.created', summary: summary, schema: 'v2')

  { ok: true, version: context[:event_version] }
end

sdk.run!(host: '0.0.0.0', port: 8080)

Custom Data Client

When your manifest includes custom_data.permissions, the SDK automatically uses the runtime token provided in the webhook payload for API calls via context[:client]:

sdk.register('case.created', version: 'v1') do |payload, context|
  project_id = payload.dig('case', 'project_id')
  custom_data = context[:endpoints].custom_data(project_id)

  list = custom_data.list('com.example.crm.contacts', 'automation_records', limit: 10, filters: { status: 'active' })

  custom_data.create('com.example.crm.contacts', 'automation_records', {
    email: 'lead@example.com',
    metadata: { source: 'webhook' }
  })

  { synced: list['data'].size }
end

SLA Alert Stream

You can also query live SLA alerts from within webhook handlers:

sdk.register('workflow.sla_status', version: 'v1') do |payload, context|
  project_id = payload.dig('case', 'project_id')
  sla_events = context[:endpoints].sla_events(project_id)

  events = sla_events.list(state: 'imminent', limit: 5)
  next { ok: true } if events['data'].empty?

  first = events['data'].first
  context[:endpoints].secrets # available if you need per-alert secrets

  context[:endpoints].log_event('sla.warning', issue_id: first['issue_id'], state: first['state'])
  { acknowledged: true }
end

Configuration

Environment Variables

KIKET_WEBHOOK_SECRET – Webhook HMAC secret for signature verification
KIKET_WORKSPACE_TOKEN – Workspace token for API authentication
KIKET_BASE_URL – Kiket API base URL (defaults to https://kiket.dev)
KIKET_SDK_TELEMETRY_URL – Telemetry reporting endpoint (optional)
KIKET_SDK_TELEMETRY_OPTOUT – Set to 1 to disable telemetry
KIKET_SECRET_* – Secret overrides (e.g., KIKET_SECRET_API_KEY)

API Reference

KiketSDK

Main SDK class for building extensions.

sdk = KiketSDK.new(
  webhook_secret: String,
  workspace_token: String,
  base_url: String,
  settings: Hash,
  extension_id: String,
  extension_version: String,
  manifest_path: String,
  auto_env_secrets: Boolean,
  telemetry_enabled: Boolean,
  feedback_hook: Proc,
  telemetry_url: String
)

Methods:

sdk.register(event, version:, &handler) – Register a webhook handler
sdk.webhook(event, version:) – Decorator for registering handlers
sdk.run!(host:, port:) – Start the Sinatra server

Handler Context

Context hash passed to webhook handlers:

{
  event: String,
  event_version: String,
  headers: Hash,
  client: KiketSDK::Client,
  endpoints: KiketSDK::Endpoints,
  settings: Hash,
  extension_id: String,
  extension_version: String,
  secrets: KiketSDK::Secrets,
  secret: Proc,              # Secret helper with payload-first fallback
  auth: {
    runtime_token: String,   # Per-invocation API token
    token_type: String,      # Typically "runtime"
    expires_at: String,      # Token expiration timestamp
    scopes: Array<String>    # Granted API scopes
  }
}

Secret Helper

The secret proc provides a simple way to retrieve secrets with automatic fallback:

# Checks payload secrets first (per-org config), falls back to ENV
slack_token = context[:secret].call("SLACK_BOT_TOKEN")

# Example usage
sdk.register('case.created', version: 'v1') do |payload, context|
  api_key = context[:secret].call("API_KEY")
  raise "API_KEY not configured" unless api_key

  # Use api_key...
  { ok: true }
end

The lookup order is:

Payload secrets (per-org configuration from payload["secrets"])
Environment variables (extension defaults via ENV)

This allows organizations to override extension defaults with their own credentials.

The Kiket platform sends a per-invocation runtime_token in each webhook payload. This token is automatically extracted and used for all API calls made through context[:client] and context[:endpoints]. The runtime token provides organization-scoped access and is preferred over static tokens.

sdk.register('case.created', version: 'v1') do |payload, context|
  # Access authentication context
  puts "Token expires at: #{context[:auth][:expires_at]}"
  puts "Scopes: #{context[:auth][:scopes].join(', ')}"

  # API calls automatically use the runtime token
  context[:endpoints].log_event('processed', { ok: true })

  { ok: true }
end

Scope Checking

Extensions can declare required scopes when registering handlers. The SDK will automatically check scopes before invoking the handler and return a 403 error if insufficient.

# Declare required scopes at registration time
sdk.register('case.created', version: 'v1', required_scopes: ['cases.read', 'cases.write']) do |payload, context|
  # Handler only executes if scopes are present
  context[:endpoints].log_event('case.processed', { id: payload['case']['id'] })
  { ok: true }
end

# Or check scopes dynamically within the handler
sdk.register('workflow.triggered', version: 'v1') do |payload, context|
  # Raises KiketSDK::ScopeError if scopes are missing
  context[:require_scopes].call('workflows.execute', 'custom_data.write')

  # Continue with scope-protected operations
  context[:endpoints].custom_data(project_id).create(...)
  { ok: true }
end

Response Helpers

The SDK provides helper methods for building properly formatted responses. These ensure your extension returns data in the format Kiket expects.

Basic Responses

# Allow (success) response
KiketSDK.allow(message: 'Operation completed')
# => { status: 'allow', message: 'Operation completed', metadata: {} }

# Deny response
KiketSDK.deny(message: 'Invalid credentials')
# => { status: 'deny', message: 'Invalid credentials', metadata: {} }

# Pending response (for async operations)
KiketSDK.pending(message: 'Awaiting approval')
# => { status: 'pending', message: 'Awaiting approval', metadata: {} }

Output Fields

Output fields allow your extension to expose generated data (like email addresses, URLs, or status info) in the extension configuration UI. Users can see and copy these values after setup.

sdk.register('extension.testConnection', version: 'v1') do |payload, context|
  # Perform setup (e.g., create Mailjet parse route)
  route = create_parse_route(webhook_url)

  # Return success with output fields
  KiketSDK.allow(
    message: 'Successfully configured',
    data: { route_id: route.id },
    output_fields: {
      'inbound_email' => route.email,
      'connection_status' => 'active'
    }
  )
end

Output fields are declared in your extension manifest:

extension:
  output_fields:
    inbound_email:
      label: Inbound Email
      description: Send emails to this address to create cases
      type: copyable
      icon: envelope
    connection_status:
      label: Connection Status
      type: badge

Supported output field types:

copyable - Text field with copy button (default)
url - Clickable URL with copy button
code - Monospace code block
badge - Status indicator with color
status - Rich status with icon

Testing

The SDK includes test helpers:

require 'kiket_sdk'
require 'rack/test'

RSpec.describe 'My webhook handler' do
  include Rack::Test::Methods

  let(:sdk) do
    KiketSDK.new(webhook_secret: 'test-secret')
  end

  def app
    sdk
  end

  it 'handles case.created event' do
    sdk.register('case.created', version: 'v1') do |payload, context|
      { processed: payload['case']['id'] }
    end

    payload = { case: { id: '123', title: 'Test Issue' } }
    body = payload.to_json
    sig_data = KiketSDK::Auth.generate_signature('test-secret', body)

    post '/v/1/webhooks/case.created',
         body,
         'CONTENT_TYPE' => 'application/json',
         'HTTP_X_KIKET_SIGNATURE' => sig_data[:signature],
         'HTTP_X_KIKET_TIMESTAMP' => sig_data[:timestamp]

    expect(last_response.status).to eq(200)
    expect(JSON.parse(last_response.body)['processed']).to eq('123')
  end
end

Rate-Limit Helper

Before enqueueing expensive jobs, inspect the current extension window:

sandbox = sdk.register('automation.dispatch', version: 'v1') do |_payload, context|
  limits = context[:endpoints].rate_limit

  if limits['remaining'] < 5
    context[:endpoints].notify(
      'Rate limit warning',
      "Only #{limits['remaining']} requests remain (reset in #{limits['reset_in']}s)",
      'warning'
    )
    next({ deferred: true })
  end

  # Continue with the heavy work
  { ok: true }
end
