# PayLink

This guide explains how to fetch a url-link that can be embedded for example in your online portal or mobile application to give user a possibility to pay the invoice directly from your application. 

Paylink is fetched with invoice number parameter and the link gives direct access to payment process without MyRopo service in between.

2. Embed the URL in your portal or mobile app.
3. The debtor can start the payment process by clicking the link.

### Parameters

* `billnum` (required): invoice number.
* `callback_url` (required): After the payment, user is redirected to this URL in your application
