Develop an extension

Adobe Experience Platform Launch has been rebranded as a suite of data collection technologies in Adobe Experience Platform. Several terminology changes have rolled out across the product documentation as a result. Please refer to the following document for a consolidated reference of the terminology changes.

A tag extension should be thought of as a (small) product with its own requirements. Determining how an Adobe Experience Platform user will want to use your extension can help you sort the functionality into what event types, condition types, action types, and data element types your extension should provide.

With that knowledge, you can plan out what components should be provided in your extension.


With a plan in place, these guides can help you understand the extension development process:

  • The getting started guide and other documents under Extension development in the left navigation are great reference material for understanding extensions. They include details on what extensions can do, how user information is stored and passed between your extension and Adobe Experience Platform, how your code is bundled into libraries, and how your extension code is interpreted and used at runtime in the browser.
  • The extension tutorial video is a great place to start.
  • The Introduction to Extensions YouTube playlist walks through the process of creating extension packages.
  • Understanding JSON Schema article.
  • JSON Lint/Validator.
  • JSON Viewer Chrome extension to highlight & print JSON & JSONP.
  • editor to help create JSON schema from your object.
  • JSON Schema Validator An online, interactive JSON Schema validator.
