PUT {endpoint}/pools/{poolId}/nodes/{nodeId}/users/{userName}?api-version=2025-06-01
With optional parameters: 
PUT {endpoint}/pools/{poolId}/nodes/{nodeId}/users/{userName}?api-version=2025-06-01&timeOut={timeOut}

Request Header

Media Types: "application/json; odata=minimalmetadata"

Name Required Type Description
client-request-id

string

The caller-generated request identity, in the form of a GUID with no decoration such as curly braces, e.g. 9C4D50EE-2D56-4CD3-8152-34347DC9F2B0.
return-client-request-id

boolean

Whether the server should return the client-request-id in the response.
ocp-date

string (date-time-rfc7231)

The time the request was issued. Client libraries typically set this to the current system clock time; set it explicitly if you are calling the REST API directly.

Request Body

Media Types: "application/json; odata=minimalmetadata"

Name Type Description
expiryTime

string (date-time)

The time at which the Account should expire. If omitted, the default is 1 day from the current time. For Linux Compute Nodes, the expiryTime has a precision up to a day.
password

string (password)

The password of the Account. The password is required for Windows Compute Nodes. For Linux Compute Nodes, the password can optionally be specified along with the sshPublicKey property. If omitted, any existing password is removed.
sshPublicKey

string

The SSH public key that can be used for remote login to the Compute Node. The public key should be compatible with OpenSSH encoding and should be base 64 encoded. This property can be specified only for Linux Compute Nodes. If this is specified for a Windows Compute Node, then the Batch service rejects the request; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request). If omitted, any existing SSH public key is removed.
