# Integrate a PayPal Hosted Payment Wall (/archive/paypal-plus/de/integrate/payment-wall)



> **Note:** **Important:** PayPal Plus Germany is not available for new integrations. PayPal provides this documentation to support existing integrations. For new integrations, see the [PayPal Checkout Integration Guide](/checkout).

PayPal PLUS replaces your Payment Selection Page (PSP) with the PayPal-hosted payment wall, which is the payment selection iframe. PayPal PLUS renders the payment wall on demand and bases it on the `approval_url` in the `links` object of the create payment response. Complete these steps to walk through a basic integration.

## Embed the iframe [#embed-the-iframe]

1. Include the JavaScript library on your checkout page using the following script:

   ```html lineNumbers
   <script src="https://www.paypalobjects.com/webstatic/ppplus/ppplus.min.js" type="text/javascript">
   </script>
   ```
2. Define a placeholder DIV on your checkout page for the PSP:

   ```html lineNumbers
   <div id="ppplus">
   </div>
   ```
3. Render the payment wall using the following script.

   ```html lineNumbers
   <script type="application/javascript">
       var ppp = PAYPAL.apps.PPP({
       "approvalUrl": "'.$approval_url.'",
       "placeholder": "ppplus",
       "mode": "sandbox",
       "country": "DE"
       });
   </script>
   ```

   In the script, the parameters are:

   | Parameter      | Type               | Description                                                                                                                                                                                                                                                                                                                  |
   | -------------- | ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
   | `approval_URL` | String             | Required. Returned as `approval_url` in the previous create payment call.                                                                                                                                                                                                                                                    |
   | `placeholder`  | String             | Required. The ID of the DOM object where the PSP is mounted in the page. The PSP sets the object's width.                                                                                                                                                                                                                    |
   | `mode`         | `enum`             | The library that loads the PSP: `live` loads from paypal.com.`sandbox` loads from sandbox.paypal.com.                          > **Note:** &#x2A;*Note:** The library emits a warning to the console if mode is set to `sandbox`. This warning is displayed in `live` mode only for required parameters.  Default is `live`. |
   | `country`      | ISO 3166-1 alpha-2 | Required. The country where the PayPal PLUS service is deployed, for example, `FR`, `GB`, `DE`, or `US` which is the default. Get the country code from the buyer's billing address.                                                                                                                                         |

## Payment methods [#payment-methods]

Based on the billing address country provided, buyers see PayPal's available funding sources for their country of origin. Additionally you can host up to 10 non-PayPal payment methods within the payment wall. For example:

<img src="https://www.paypalobjects.com/ppdevdocs/img/docs/paypal-plus/credit-card-de.png" />

## Payment Buttons [#payment-buttons]

A payment button is provided with the payment wall and can be set on the `buttonLocation` parameter to be:

* `inside`. Renders the button within the iframe.
* `outside`. Uses a DOM object that you provide to render the button outside the iframe.

The **Continue** button is a variation of the outside button. Use the **Continue** button to direct a buyer to an additional page in your checkout flow that's outside the iframe. On this additional page, place a button that redirects the buyer back to a PayPal landing page. Use the `PAYPAL.apps.ppp.doCheckout` function to implement the redirect.
