Kiket Ruby SDK

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

Features

• 🔌 Webhook decorators – define handlers with sdk.webhook("issue.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('issue.created', version: 'v1') do |payload, context|
  summary = payload['issue']['title']
  puts "Event version: #{context[:event_version]}"

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

  { ok: true }
end

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

  context[:endpoints].log_event('issue.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, set extension_api_key (or the KIKET_EXTENSION_API_KEY environment variable) so outbound calls to the extension API include X-Kiket-API-Key:

sdk.register('issue.created', version: 'v1') do |payload, context|
  project_id = payload.dig('issue', '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: '[email protected]',
    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('issue', '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_EXTENSION_API_KEY – Extension API key for /api/v1/ext/** endpoints (custom data client)
• 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)

Manifest File

Create an extension.yaml or manifest.yaml file:

id: com.example.marketing
version: 1.0.0
delivery_secret: sh_production_secret

settings:
  - key: API_KEY
    secret: true
  - key: MAX_RETRIES
    default: 3
  - key: TIMEOUT_MS
    default: 5000

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
}

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

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

    post '/v/1/webhooks/issue.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

Publishing to GitHub Packages

When you are ready to cut a release:

1. Update the version in kiket-sdk.gemspec.
2. Run the test suite (bundle exec rspec) and linting (bundle exec rubocop).
3. Build gem:

   gem build kiket-sdk.gemspec

4. Commit and tag the release:

   git add kiket-sdk.gemspec
   git commit -m "Bump Ruby SDK to v0.x.y"
   git tag ruby-v0.x.y
   git push --tags

5. GitHub Actions will automatically publish to GitHub Packages.

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
