I think you should ask this question in vRealize Automation Tools . Adding custom attributes will require REST API call if you are trying to do it from a vRO workflow. Once you know what REST API you have to call you can do it from vRO workflow
Hi Thanks for the reply,
I can able to add it from the workflow.
I need to run the workflow with the Blue print.
For ex: If a requester requests the VM from the Blue print. The attributes should add automatically at the time of provisioning.
