How to add Petition Form to a Shopify store

Embed Petition Form on Shopify

01

Create a Petition Form app for Shopify on Common Ninja

First, create a Shopify Petition Form app on Common Ninja. On the apps catalog, find the Petition Form and enter the Editor.

02

Save the Petition Form app

When you're done creating the Petition Form app, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Petition Form Embed Code

When you're ready to add the Petition Form app to your Shopify store, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the app embed code. In the next steps, you will paste this code into your Shopify store.

04

Paste the code to your Shopify website’s HTML field.

Next, go to your Shopify store editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Shopify’s editor. Add it to your page, and paste the Petition Form Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Petition Form app on your Shopify store.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Petition Form app on your Shopify app. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Shopify store’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Petition Form app to your Shopify store. You can do this by putting it straight into your Shopify store's HTML code.

Why Use This Widget

Use the Petition Form widget when your goal is to gather visible support around a cause, policy, or initiative. It lets visitors sign with their details in a structured way that can be stored, exported, and used in campaigns or official submissions. You can describe the issue clearly, show how many people have already signed, and keep participants informed through notifications. This tool is valuable for nonprofits, advocacy groups, community organizers, and internal company initiatives that depend on collective backing. By hosting the petition on your own site, you control the experience, keep visitors connected to further information, and build a base of supporters who feel involved and heard.
