# Embed offerwall iframe

Creating your Rewards Center iFrame is easy and simple. You just need a page with enough space to run it on your webpage/webapp.

You’ll need to dynamically generate the Rewards Center link based on the RapidoReach UID. This ensures that every user gets the right credit for their activity. First generate the RapidoReach UID using a script on the server, and pass that to the website.

## Embed the iframe

Append the dynamically generated User ID to the end of the User Greeting. userGreeting = [https://www.rapidoreach.com/offerwall/?userId=](https://www.rapidoreach.com/offerwall/?userId=) Example:

Join User Greeting with the RapidoReach UID:

```lang-bash
https://www.rapidoreach.com/offerwall/?userId= + 597a0ed87760ae04c29975ee-1sJ57hgit-838ab4b72d221a585af8b4be7a540234
```

## Becomes User Greeting URL:

```lang-bash
https://www.rapidoreach.com/offerwall/?userId=597a0ed87760ae04c29975ee-1sJ57hgit-838ab4b72d221a585af8b4be7a540234
```

Enclose your User Greeting URL in the iframe tags as shown below:

```HTML
<!-- Template -->
<iframe src="{{userGreetingURL}}" width="880px" height="2500px" frameborder="0" scrolling="no" name="RewardsCenter"></iframe>
```
