It’s very easy to add Common Ninja’s HTML code to BigCartel. Note, however, that the option to edit HTML code on BigCartel is for premium users only.
1. First, copy the app’s HTML code. To do so, in the app’s dashboard, go to “Add to Website”. Here, click on the green button (it will automatically copy the code).
2. Then, go to your BigCartel dashboard, and choose the “Code” tab.
3. Then, choose the page you want to edit. You will now be able to edit the page's HTML code. Paste the code you’ve copied before to where you want the app to appear. When you are done, click “Publish”. That’s it. You should see Common Ninja’s app on your page.
