Use case
OTP email
When you need a short numeric or alphanumeric code for login or step-up auth. Copy the HTML into your app and send with one API call.
Subject line ideas
- Your verification code
- Login code
- {{CODE}} is your code
HTML example
Replace placeholders in your app before send. This is not a Notify template product — it is a starting snippet.
<p>Your code is:</p>
<p style="font-size:24px;font-weight:bold;letter-spacing:4px;">{{CODE}}</p>
<p>It expires in 10 minutes.</p>Send with Notify
const res = await fetch('https://notify.cx/api/email/send', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'x-api-key': process.env.NOTIFY_API_KEY
},
body: JSON.stringify({
to: 'user@example.com',
from: 'noreply@yourdomain.com',
subject: "Your verification code",
message: `${html}`
})
});Security notes
- Short codes with short TTL
- Limit attempts
- Never log codes in plain text client-side
