Re: How to do a simple health check of vAPI (vRO 7.3 and vCenter 6.0)

1) All these actions with pscoe in their module name are not part of vAPI plug-in, I guess you've got them from some other plug-in/package.

2) Yes, by default it uses the credentials you provided in configuration workflows to import vAPI metamodel and register vAPI endpoint. If you want to use a different credentials for a particular vAPI method call, you can override them when you acquire a client from endpoint. That is, instead of

var client = endpoint.client();

you can use the form

var client = endpoint.client(someuser, somepassword);
