Pay by Link

The link is
the integration.

Generate a payment URL with one API call (or one button in the dashboard). Share it on email, Slack, WhatsApp, an invoice, or a QR code. Customers pay — you get a webhook.

What's included

  • Fixed amount, open amount, or pick-from-list
  • Single-use or multi-use links
  • Custom expiry windows
  • Per-link conversion stats (views vs. payments)
  • QR code generated automatically
  • Works with any payment method the customer picks
