§ Part V / V · Questions

Things merchants
ask about links.

Answered
In full, with links

Q.01Is this really no-code?

Yes. Sign up, open the dashboard, click Payment Links → New, fill in amount and accepted coins, copy the URL. That's it. If you also want programmatic creation, the POST /dashboard/payment-links endpoint above takes the same fields.

Q.02Can one link accept many payments?

Today each link is single-use — when the threshold is met the link settles and closes. For recurring or persistent flows, use Subscriptions or Static Address.

Q.03What expires after what?

expires_in (seconds) sets the link lifetime — defaults to 24h. After expiry the URL returns an expired state and no new payments are accepted. Already-landed deposits remain credited.

Q.04How does the customer know what they pay?

The hosted page shows a coin picker scoped to your accepted_coins, the USD price, the real-time crypto equivalent (pinned at coin pick), and a QR + address. The UI matches SETTLEMENT register and your brand assets if you configure them.

Q.05Can I add a callback webhook per link?

Yes — each link accepts a callback_url. If omitted, the merchant's default webhook URL from /dashboard/settings/webhook is used. HMAC-SHA512 signing applies either way.
