algorithm.package.check (Validate algorithm)

algorithm.package.check: Validate algorithm

algorithm.package.check · device scope · permission Config

What it does

Validates an on-device algorithm package. Input: param, ref, type. Returns result. Each call runs once.

Request URL

POST https://openapi-[DataCenter].easy4ip.com/openapi/v2/device.service.invoke

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. See Permission codes. Shared devices must satisfy one alias in the capability row share_auth_code (for example Config,config). A timeout does not mean the operation did not execute.
