Use case
Failed payment email
When a subscription charge fails and the user must update payment. Copy the HTML into your app and send with one API call.
Subject line ideas
- Payment failed — update your card
- We could not process your payment
- Action needed: billing
HTML example
Replace placeholders in your app before send. This is not a Notify template product — it is a starting snippet.
<p>We could not process your latest payment.</p>
<p>Please update your payment method to avoid interruption.</p>
<p><a href="{{BILLING_URL}}">Update billing</a></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: "Payment failed — update your card",
message: `${html}`
})
});Security notes
- Do not include full card numbers
- Link to a secure billing portal
- Be clear about grace period / access impact
