Extensions are only available on select plans. Please reach out to your Customer Success Manager to request access.
You can create a extension under Implementation > Extensions. Each extension has a unique ID that identifies it on the page. If the same extension is inserted in multiple places, the code will only be included once and each instance will call into it by ID. Extensions can be inserted on multiple pages, but you can choose one Editor URL that will appear in the extension builder. The Name and Description are human-readable text in the Optimizely interface.
