Update certificate of SSL profile via REST API

Hi All,

Is there a way to update the exisiting certificate binded in the SSL profile of F5 ? I have installed the certificate already but not really sure how to add that cert to the SSL profile using iControl REST API. 

I tried sending the request as shown below, but it always throws error 400. 

URL: https://hostname/mgmt/tm/ltm/profile/client-ssl/profile_name?ver=15.1.2.1

POST Body:

{
	"cert": "/Common/cert_name.crt",
	"chain": "/Common/ca_package.crt",
	"key": "/Common/key_name.key"
}

The error i am getting is:

{
    "code": 400,
    "message": "one or more configuration identifiers must be provided",
    "errorStack": [],
    "apiError": 26214401
}
