Frequently asked questions
Which alert channels does Uptime Tracker support?
Fourteen: Email, Slack, Discord, Telegram, Webhooks, SMS, Microsoft Teams, Google Chat, Pushover, ntfy, Gotify, Mattermost, Rocket.Chat, PagerDuty. Email, Slack, Discord, Telegram and webhooks are free; the others need Pro or Team.
Can Uptime Tracker send SMS alerts?
Yes, on Pro and Team. Numbers are verified with a code first, messages reach 231 countries, and they are paid from prepaid credit whose per-country price is shown before you buy. Voice calls are not offered.
How do I verify Uptime Tracker webhooks?
Every webhook request carries an HMAC-SHA256 signature over a timestamp and the exact request body, using a signing secret you choose. Recompute the signature with your secret, compare in constant time, and reject requests whose timestamp is outside your replay window.
Does Uptime Tracker integrate with PagerDuty?
Yes, on the Team plan, through the PagerDuty Events API v2. The incident ID is used as the de-duplication key, so retries and reminders update the same PagerDuty alert and recovery resolves it.
