# Reward preorders and signups with Smile.io

> Give customers Smile.io loyalty points for preorders and back in stock signups.

Use this guide if you run a Smile.io loyalty program and want to reward customers who commit before a product is in stock. By the end, customers will earn the points you choose in Smile.io when they place a preorder, pay a preorder balance, sign up for a back in stock alert, or buy after an alert.

## Before you begin

| Requirement | Detail |
|---|---|
| A paid STOQ plan | The **Connect Smile.io** toggle is disabled on the free plan. |
| A Smile.io account | You sign in to Smile.io to approve the connection. |

## What customers will see

STOQ tells Smile.io when a customer does one of the actions below. Each one appears in Smile.io as a way to earn, and you choose in Smile.io which ones earn points and how many. STOQ never decides the reward.

| Action | When it's sent |
|---|---|
| **Placed a preorder** | A customer places a preorder for a product in a preorder offer. |
| **Paid a preorder balance** | The remaining balance of a partial payment preorder is charged, so customers earn on both the deposit and the balance. |
| **Signed up for a back in stock alert** | A customer signs up through your 'Notify me' button. Each customer earns this at most once a day, so signing up for many products doesn't add up. |
| **Bought after a back in stock alert** | A customer buys a product after getting a back in stock alert for it. |

Customers see their points in your Smile.io rewards panel, the same as any other way to earn.

## Set it up

On a phone, this menu is collapsed. In the **Shopify mobile app**, tap the **STOQ** logo at the top of the screen to open it, then choose the section named below. There is no hamburger icon. See [Finding the STOQ menu](https://help.stoqapp.com/general/getting-started-with-stoq/#finding-the-stoq-menu).

1. **Open the Smile.io card**

   1. In the left menu bar of the STOQ app, click **Back in stock alerts**.
   2. Click the **Settings** tab, then open the **Integrations** sub-tab.
   3. Click **See integrations** to open the full **Integrations** page.
   4. In the **Marketing** section, find the **Smile.io** card and click **Set up**.

2. **Turn on Connect Smile.io**

   Turn on **Connect Smile.io**. Smile.io opens in a new browser tab.

3. **Approve the connection in Smile.io**

   Sign in to Smile.io and approve STOQ. Back in STOQ, the card shows **Your Smile.io account is connected.**

4. **Set the points in Smile.io**

   Click **Open Smile.io**. In your Smile.io admin, add the STOQ actions you want to reward as ways to earn, and set how many points each one gives.

## Check your setup

1. Sign up for a back in stock alert on your store with an email that has a Smile.io account. See [Test back in stock alerts](https://help.stoqapp.com/back-in-stock/test-back-in-stock-alerts/).
2. In Smile.io, open that customer and confirm the points from **Signed up for a back in stock alert** show up.

## Troubleshooting

### The Connect Smile.io toggle is greyed out

It's a paid-plan feature. Upgrade your STOQ plan to turn it on.

### A customer didn't get points for a signup

Check these:
1. You added **Signed up for a back in stock alert** as a way to earn in Smile.io.
2. The customer signed up with an email address. A signup with only a phone number isn't sent to Smile.io.
3. The customer hasn't already earned it today. Each customer earns the signup action at most once a day.

### STOQ shows Couldn't connect to Smile.io

Turn **Connect Smile.io** on again, and finish signing in and approving STOQ on the Smile.io tab before you close it.

## FAQ

### Does STOQ decide how many points customers get?

No. STOQ only tells Smile.io what the customer did. You set the points for each action in Smile.io.

### Why is the preorder balance its own action?

A partial payment order's total in Shopify is only the deposit, so a spend-based rule would underpay the customer. Rewarding **Paid a preorder balance** lets customers earn on the rest when it's charged.

### Do existing preorders and signups earn points?

No. Only actions that happen after you connect Smile.io are sent.

### How do I stop sending actions to Smile.io?

Turn off **Connect Smile.io** on the Smile.io card. Points customers already earned stay in Smile.io.
