Registrations:

Your application must be registered with Bentley’s OpenId provider in order to access resources from Bentley services such as iModelHub. A registration identifies your application to other services and specifies what resources your application can access such as iModels, reality data, and user emails.

Also, you need an iModel to test your application. If you don’t have your own iModel you can request one below by selecting ‘Registered Projects’. When you register a new project we will create a Bentley CONNECT project for your personal use. You can seed the project with an iModel copied from our sample library, with a copy of an iModel that you supply.
