# Modal

> Integrate VPOS-2 as a modal payment form inside your website.

The **Alignet Modal** lets a merchant start a payment from its website and display VPOS-2 in a modal window. The request is built in an HTML form, signed with the merchant SHA-2 key, and opened through JavaScript.

<Warning>
  The official guide states that this procedure does not apply to merchants in Peru. Confirm the appropriate method with your acquirer or contact [integraciones@alignet.com](mailto:integraciones@alignet.com).
