Login in vCloud Director using REST API Client - POSTMAN

• Nowadays most of the virtualization products support REST-API.  
• I first learned to interact using rest-api is with RavelloSystems(a cloud platform by Oracle)
• The best client I have come across for it is POSTMAN client available for windows, mac & Linux. I have installed it on my MacBook & windows 10 machine. 
• So this time I wanted to interact with vCloud Director 8.2 & 9.0 using REST-API
• After a long day meeting and looking for how to log in successfully in vCD using postman client, somehow I figured it late night
• So the basic options that we use in it are GET, PUT, POST & DELETE.
• So if you have worked on HTML it makes it easy to understand the output.
• As VMware has already started in vCenter 6.5 - REST API explorer.

Steps to login in vCD using POSTMAN

• URL for vCD i.e
  https://IP or FQDN/api/sessions
• Authentication- Basic (As per snapshot no. 1)
      Username- administrator@system   :- If you are a system administrator.
      I found it difficult for the username which took me this much time. So this user can be a LDAP integrated user or Active Directory.
      Password-  As per your directory
• Once authorized with Status:200 OK .  In the AUTHORIZATION tab as highlighted, we have HEADERS tab where we will recieve a x-vcloud-authorization: token.
• Instead of using your credentials for authentication, we can use the custom header (As per snapshot no. 2 & 3).
• Now we are ready to work on this REST-API for interaction using postman client.
