How to Add a Standalone
ESXi
Host to
vCenter Server

You can use the
vSphere Automation
REST
APIs to add a standalone host to a
vCenter Server
instance.
Add a single
ESXi
host to a
vCenter Server
instance by using the
POST https://
<vcenter_ip_address_or_fqdn>
/api/vcenter/host
request and submitting a
HostCreateSpec
JSON object in the request body. When you construct the host object, make sure that you set values for the IP address or the DNS resolvable host name and the administrator credentials.
