# Embedding

Find out which embedding option works for you.\
No matter if you work with a [custom Gateway](/developer/guides/gateway.md) or the [Payrexx tools](https://docs.payrexx.com/merchant/payrexx-administration/tools).

{% hint style="warning" %}
Prior to this article, you should have created a [Gateway ](/developer/guides/gateway.md)or configured a [Payrexx tool](https://docs.payrexx.com/merchant/payrexx-administration/tools)!
{% endhint %}

## Redirect

After the payment, your buyer will be redirected back to your site.

{% hint style="success" %}
We recommend redirection for complex integrations using the Payrexx API
{% endhint %}

## iFrame

The iFrame lets you seamlessly integrate a payment form into your website.\
This can be a good marketing website integration opportunity.

### Limited Payment Providers in iFrame

Some payment providers or payment methods do not allow embedding in an iFrame and cannot be used. These include *PayPal* and *Coinbase*.

Others can only be used with specific setup configurations. Such as *Google Pay*.

*PostFinance* is disabled in iFrames if the client device disallows 3rd party cookies. This is the standard behaviour for iOS and MacOS.

## Modal Window

Your buyer will never leave your website with the modal window. The payment form appears in a pop up window.
