Define precisely who gets notified, when, and how with a fully programmable workflow

Stop managing alerts through dashboards. When services fail, every second counts. Checkly transforms alerting and incident management by letting teams define their entire monitoring strategy in code. Configure custom alert conditions, route notifications, and automate response workflows—all using your existing development tools and frameworks.

alerts.check.ts
import { SmsAlertChannel } from '@checkly/cli/constructs'

const smsChannel = new SmsAlertChannel('sms-channel-1', {
  // receive recovery notifications
  sendRecovery: true,
  // receive failure notifications
  sendFailure: true,
  // receive degraded notifications [API checks only]
  sendDegrade: true,
  // receive a notification when a SSL/TLS certificate expires [API check only]
  sslExpiry: true,

  phoneNumber: '0031061234567890',
})

Go on. Pick a channel. Any channel.

Choose channels to alert teams in from a wide range of preconfigured integrations or use our custom web hooks to build your own. With everything from email, to Pagerduty, to Rootly, and SMS, you can alert the right team with the right information to get any downtime solved.

Alert channels: phone, mail, SMS, webhooks, Pageduty, Splunk, MS team, GitLab, Slack

About our webhooks...

We take webhooks very seriously. That's why we give you complete control over the webhook payload to hook up Checkly's alerts to basically any system out there.

webhook.check.ts
import { WebhookAlertChannel } from '@checkly/cli/constructs'

const webhookChannel = new WebhookAlertChannel('webhook-channel-1', {
  name: "Pushover webhook",
  method: "POST",
  url: "https://api.pushover.net/1/messages.json",
  template: `{
    "token":"FILL_IN_YOUR_SECRET_TOKEN_FROM_PUSHOVER",
    "user":"FILL_IN_YOUR_USER_FROM_PUSHOVER",
    "title":"{{ALERT_TITLE}}",
    "html":1,
    "priority":2,
    "retry":30,
    "expire":10800,
    "message":"{{ALERT_TYPE}} {{STARTED_AT}} ({{RESPONSE_TIME}}ms) {{RESULT_LINK}}"
  }`
})
