  "password": "string",
  "labels": "map<string, string>"
}

Field	Description
registry_id	string Required field. ID of the registry to create a device in. To get a registry ID, make a yandex.cloud.iot.devices.v1.RegistryService.List request.
name	string Required field. Name of the device. The name must be unique within the registry.
description	string Description of the device.
certificates[]	Certificate Device certificate.
topic_aliases	object (map<string, string>) Alias of a device topic. Alias is an alternate name of a device topic assigned by the user. Map alias to canonical topic name prefix, e.g. `my/custom/alias` match to `$device/{id}/events`.
password	string Device password. The password must contain at least three character categories among the following: upper case latin, lower case latin, numbers and special symbols.
labels	object (map<string, string>) Resource labels as `key:value` pairs.

Certificate

Specification of a device certificate.

Field

Description

certificate_data

string

Public part of the device certificate.

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
created_at	google.protobuf.Timestamp Creation timestamp.
created_by	string ID of the user or service account who initiated the operation.
modified_at	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	CreateDeviceMetadata Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	Device The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.

CreateDeviceMetadata

Field

Description

description	string Description of the device. 0-256 characters long.
topic_aliases	object (map<string, string>) Alias of a device topic. Alias is an alternate name of a device topic assigned by the user. Map alias to canonical topic name prefix, e.g. `my/custom/alias` match to `$device/abcdef/events`.
status	enum Status Status of the device. `STATUS_UNSPECIFIED` `CREATING`: Device is being created. `ACTIVE`: Device is ready to use. `DELETING`: Device is being deleted.
monitoring_data	DeviceMonitoringData Device monitoring data, returns if FULL view specified.
