detection.door.keyData (Read key data)

detection.door.keyData: Read key data

detection.door.keyData · device scope · permission Config

What it does

Read key data. Struct fields follow model and device.property.get read-back.

Request URL

POST https://openapi-[DataCenter].easy4ip.com/openapi/v2/device.property.get

Minimum permission

The administrator does not need an extra permission on a device they bound. A shared device needs the basic configuration permission. A bound sub-user does not. A sub-account needs Config. Do not send channelId on device-scope capabilities. Mixing device and channel properties in one request returns DV2008.

Request parameters

NameTypeRequiredDescription
tokenStringyesAccess token for an administrator, sub-user, or sub-account
deviceIdStringyesDevice serial number
productIdStringnoOptional. If sent and it does not match the device model → DV2009
propertiesArrayyes["detection.door.keyData"]

For common request fields and signing, see Signing conventions and Common request payload.
