How do I get notified when someone signs up?
Add one HTTP POST to your signup handler with Lert. The moment a new user is created, send their name to your Lert link and your phone buzzes — even locked in your pocket. No account, no API keys, no SDK.
Those first few sign-ups are the most exciting moments of any project — and the easiest to miss if you're not staring at your analytics. Lert puts each new user straight on your lock screen. You already have a function that creates the account; you just add one line to it. Because your Lert link is the credential, there's no key to configure and nothing to install.
Set it up in under 30 seconds
- Download the app. Open it once — there's no account to create. Your private link is on screen.
- Copy your link. One tap copies
https://lert.dev/p/your-id. - Drop a POST into your signup handler. Right after the user record is saved, fire it off with the new user's email.
From then on, every new sign-up buzzes your phone.
Example: inside a Node signup handler
app.post("/signup", async (req, res) => { const user = await db.users.create(req.body); await fetch("https://lert.dev/p/your-id", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ title: "New sign-up 🙌", body: `${user.email} just joined`, tag: "signups" }) }); res.json({ ok: true }); });
No auth token, no SDK — just one fetch. Not a coder? If your sign-ups come through a form builder or CRM, connect it with Zapier and paste your link into a webhook step.
Tip: wrap the POST so a Lert hiccup never blocks a real sign-up — fetch(...).catch(() => {}). The account creation is what matters; the buzz is a bonus.
