# How to install Pandectes widgets on older Shopify themes (Legacy theme support)

**Legacy theme support** is for stores on **older themes** that cannot use theme app sections. Instead of adding blocks in the theme editor, you copy **ready made code snippets** from the app and paste them into your theme files.

This guide covers:

* Customer data requests 
* Cookie declaration
* Do not sell my data
* EU withdrawal button

Each instructions view walks you through the **standard Online Store 2.0** setup first.

At the **bottom** of those instructions, you will see a panel:

If the above doesn't work for your store, check below:

That panel has two links:

* **Legacy theme support install instructions** — for older Shopify themes 
* **Custom storefront (headless) install instructions** — for Hydrogen or other external frontends

Click **Legacy theme support install instructions** to open the legacy setup page for your shop.

## When should you use legacy theme support?

Use it when **all** of the following are true:

* Your theme is an **older Shopify theme** that does not support Online Store 2.0 app sections, or you cannot add Pandectes blocks through the theme editor.
* You are **not** using a **custom headless storefront**. Headless stores should use the **Custom storefront** link in the instructions footer instead.

If your theme **does** support Online Store 2.0, follow the main steps in the instructions modal. Legacy snippets are only for when that standard flow is not possible.


## Plan requirement

Legacy theme support is available on **Premium and higher** plans.

If you are on a lower plan, install snippets appear locked in the app and you will see an upgrade prompt.


## How to set up a widget (step by step)

Every widget needs **three things**: app configuration, legacy theme support turned on, and snippets pasted into your theme.

### Step 1  Configure the widget in Pandectes

Open the widget’s settings page, set up the content and options you want, and click **Save**.

| Widget | Settings page |
| ---- |
| Customer data requests | Customer Data Requests |
| Cookie declaration | Cookies Declaration |
| Do Not Sell | Do not sell my data |
| EU withdrawal button | Withdrawal |

Saving updates what the storefront widget will show. It does **not** add the widget to your theme by itself.

### Step 2  Open legacy install instructions

1. On the same widget page, open **View instructions** or **Instructions**.
2. Scroll to the bottom panel: *If the above doesn't work for your store, check below:*
3. Click **Legacy theme support install instructions**.

You are taken to the legacy setup page for your shop.

### Step 3  Enable legacy theme support

On the legacy setup page:

1. Click **Enable** on the status banner at the top.
2. The app prepares install snippets for your shop.

When legacy theme support is **on**, you can view and copy snippets for **Eu Withdrawal button**, **Customer Data Requests**, **Do not sell my data**, and **Cookie declaration**.

When it is **off**, snippets stay hidden until you enable it.

### Step 4  Copy and paste the snippet for your widget

Still on the legacy setup page, open the section that matches the widget you are installing and follow the copy and paste steps.

Always copy snippets **from the app**. Do not edit the code or build the URLs yourself.


## Install steps for each widget

Enable legacy theme support first (steps above), then use the matching section on the legacy setup page.

### EU withdrawal

1. Open the Shopify page where the form should appear (or create one).
2. Press on the "Show Html" on the page editor.
3. Paste the **EU Withdrawal button snippet**.
4. Save your page.

If you use Online Store 2.0 instead, name your page template `withdrawal-requests`.

### Customer data requests (DSR)

1. Open the Shopify page where the form should appear (or create one).
2. Press on the "Show Html" on the page editor.
3. Paste the **Customer data requests snippet**.
4. Save your page.

If you use Online Store 2.0 instead, name your page template `datarequests`.

### Do Not Sell / CCPA

1. Open the page where visitors should opt out.
2. Press on the "Show Html" on the page editor.
3. Paste the **Do Not Sell snippet**.
4. Save your page.

If you use Online Store 2.0 instead, name your page template `donotsell`.

### Cookie declaration

1. Open your cookie declaration page.
2. Press on the "Show Html" on the page editor.
3. Paste the **Cookies** **declaration snippet**.
4. Save your theme.

If you use Online Store 2.0 instead, name your page template `declaration`


## Troubleshooting

| What you see | What to try |
| ---- |
| Snippets are blurred or show a lock icon | Upgrade to **Premium** or higher |
| Message: “Enable legacy theme first” | On the legacy setup page (opened from instructions footer), click **Enable** |
| Cannot find legacy setup | Open **View instructions** on any supported widget and click **Legacy theme support install instructions** at the bottom |
| Widget is blank on the live store | Confirm the snippet is on your **published** theme and on the correct page |
| Widget shows old text or settings | Save again in the widget’s Pandectes settings, then hard refresh your storefront |
| Widget loads twice or behaves strangely | Do not use manual snippets **and** theme app sections for the same widget — pick one method |
