Installation with Onepage

In the editor via the code icon on the left: “Site Code”, area “<body>”.

Requirement: Access to the editor of your project.

Step by step

1. Open your project and any page in it. The code then applies to the whole project.
2. Click the code icon in the left sidebar. It opens the input field for custom code.
3. Choose “Site Code”. This code applies to all pages of the project; “Page Code” would only apply to the one page.
4. Paste the line of code into the “<body>” area. According to Onepage, that is where code belongs that runs on the page, for example a chat window.
5. Save and click “Update” or “Publish” so the change becomes visible.
