# App Embeds Overview

> Turn on the ReferRush widgets in your Shopify store so customers can see, join and share your referral program.

ReferRush adds three widgets to your Shopify store. You switch each one on once from your Shopify admin, and each takes less than a minute.

> **[Notification Popup](/setup/app-embeds/notification-popup.md)**
>
> Shows friends their gift when they open a referral link, and tracks the referral.

> **[Signup Form](/setup/app-embeds/signup-form.md)**
>
> A floating button that lets any visitor join and get their referral link.

> **[Thank You Page](/setup/app-embeds/thank-you-page.md)**
>
> Shows customers their referral link right after they buy.

> [!WARNING]
>
> **The Notification Popup is required.** Referral links only track visitors when it is turned on, so without it no referral sales are counted.

## Where each one is turned on

| Widget | Turn it on in Shopify | Customize it in ReferRush |
| - | - | - |
| Notification Popup | Online Store → Themes → Customize → App embeds | Channels → Notification Popup |
| Signup Form | Online Store → Themes → Customize → App embeds | Channels → Signup Form |
| Thank You Page | Settings → Checkout → Customize → Apps | Channels → Checkout Extension |

## Recommended order

**1. Set your offer and reward**

The widgets show the offer and reward you set in [Offer & Reward](/setup/offer.md), so set those first.

**2. Turn on the Notification Popup**

This makes referral links work. [Set it up](/setup/app-embeds/notification-popup.md).

**3. Turn on the Signup Form**

This lets any visitor join your program. [Set it up](/setup/app-embeds/signup-form.md).

**4. Add the referral link to your Thank You page**

This asks every customer to refer right after they buy. [Set it up](/setup/app-embeds/thank-you-page.md).

> [!TIP]
>
> To check that the popup and signup form are on, open them in your ReferRush dashboard under **Channels**. Each page shows an **ACTIVE** badge once its embed is turned on in your live theme.
