Learn about the actions folder

The actions folder for this sample app contains a few JavaScript files and one folder called commerce. The JavaScript shown is an excellent example file that can be reused if it is relevant to your work. This folder can save you time in development efforts when connecting to the Adobe Commerce application using OAuth and REST.

The actual names of folders in this example are arbitrary, but knowing their names can help you interpret the sample code. By using a meaningful naming convention, you can avoid confusion if the application grows more complex.

Who is this video for?

  • Developers new to Adobe Commerce with limited experience with Adobe App Builder who are learning about the actions folder in the sample application.
