# Payment Links

> Generate hosted payment and receipt URLs for invoices and orders.

Turn published invoices or orders into shareable URLs customers can pay on a Dollr-hosted page with **mobile money** or **card** — no Dollr account required.

**Try in API Reference:** [Payment link](/api-reference/links/get-payment-link) · [Receipt link](/api-reference/links/get-receipt-link)

## When to use

* Send a pay link by SMS, email, or WhatsApp
* Redirect customers after checkout to a receipt page
* Hosted checkout without building your own payment form — see [Hosted checkout](/guides/hosted-checkout)

Requires the source to be published (`ACTIVE` or later). See [Invoices](/api/invoices) and [Orders](/api/orders).
