How do I use the REST API?

Many apps can be developed for and used with 3dcart’s REST API functionality.  The REST API is commonly used by third-party applications to connect to your store and offer functionality with their product or service.  These third party apps will typically provide you the details to enable their app, including their App API Key.

The REST API should be enabled by default with your 3dcart account.  To confirm if it is available for your store please login into your 3dcart Online Store Manager and use the left hand navigation menu to:

  1. Go to Modules
  2. Once there, use the search bar at the top to search for “REST API”

Once completed, you will see the REST API icon and a link labeled “Change Settings” which will allow you to manage and add your REST API Connected apps.
