Domain expiry alert on Telegram
Every week, check when your domains expire and get a Telegram alert 30 days before.
How it works
Trigger: Schedule — Mondays at 9:00
- List your domains in the Code step.
- Look up each domain's registration with the free RDAP service.
- Alert on Telegram when one expires within 30 days.

Code
JavaScript used in the Code steps — already included in the template below.
// The domains to watch. Add yours here.
const DOMAINS = ["yourcompany.com", "shop.yourcompany.com"];
return DOMAINS.map((domain) => ({ json: { domain } }));// Mode: Run Once for Each Item
// Reads the expiry date from the RDAP answer and works out the days left.
const expiry = ($json.events || []).find((e) => e.eventAction === "expiration")?.eventDate;
const domain = $json.ldhName ? String($json.ldhName).toLowerCase() : "unknown";
if (!expiry) return { json: { domain, daysLeft: 9999, expires: "unknown" } };
return {
json: {
domain,
expires: expiry.slice(0, 10),
daysLeft: Math.floor((new Date(expiry) - Date.now()) / (24 * 60 * 60 * 1000)),
},
};Build it

}In Make, create a new scenario and add these modules in order:
- Schedule the scenario: Mondays 9:00
- Tools › Set variable / Iterator + Array aggregator (same logic as the Code step)
- HTTP › Make a request
- Tools › Set variable / Iterator + Array aggregator (same logic as the Code step)
- Filter on the next route: “Expires within 30 days?”
- If yesTelegram Bot › Send a Text Message or a Reply
- Every module run uses Make operations — the free plan includes a monthly quota.
- Make's built-in functions (map, sum, formatDate…) can replace most Code steps; for complex logic use a code module.
- Module and step names can differ slightly as Make and Zapier update their apps.
In Zapier, create a new Zap and add these steps in order:
- Schedule by Zapier — Mondays 9:00
- Code by Zapier — Run JavaScript (paste the code from the Code section)
- Webhooks by Zapier — GET
- Code by Zapier — Run JavaScript (paste the code from the Code section)
- Filter by Zapier: “Expires within 30 days?”
- If yesTelegram — Send Message
- Zaps with more than two steps need a paid Zapier plan.
- Webhooks, Filters/Paths and Code by Zapier are premium features on some Zapier plans.
- Code by Zapier runs JavaScript: reuse the code shown above, reading inputs from inputData instead of $json.
- Module and step names can differ slightly as Make and Zapier update their apps.
Tips
- Some country domains (like .eg) don't publish RDAP data; check those at your registrar.
