How to upgrade the cloudera runtime with cloudera rest api?

I am new to cloudera rest api.

I try to upgrade the cloudera runtime with rest api instead of the web-ui for automation. 

I am able to download the CDH with rest api. 

curl -X POST -u admin:admin "http://{url}:7180/api/v44/clusters/{cluster-name}/parcels/products/CDH/versions/7.1.8-1.cdh7.1.8.p0.30990532/commands/startDownload"

I am stuck on it ask for upgrade the cluster when it finish the download. From the Web-UI. 

it is a series of process.

I can skip all the checkup step(I understand the risks) and upgrade the cluster.

How to do that with the rest api?

Thank you very much!!
