+
+ The minimal requirement of being able to start using the portal is to have an HPE user account or an HPE GreenLake Account. To leverage the HPE GreenLake platform APIs, the user will need to create an API client credentials for the HPE GreenLake platform. With the API client credentials, the user will be able to create an access token.

+## Summary 
 
 This blog post is intended to help you get started with the HPE GreenLake Developer Portal. Additional posts on the HPE GreenLake platform APIs have been produced by the HPE Developer Community team. There is a three-part series that takes you through the preparation steps you need  to use the APIs for common platform services and walks you through the steps required to obtain an OAuth access token to make secure REST API calls to the HPE GreenLake platform APIs. Then, you can dive into the Postman collection to learn how you, as an IT (Information Technology) administrator of the HPE GreenLake platform, can configure and manage workspace resources (users’ identity, devices, and subscriptions), and how you can track activities within your workspace to monitor the overall health of services and devices in your workspace.
