JSON value number array addition/sum

Configuration
1

Hello,

I have a JSON based api that has a value that returns an array of numbers, like this:

“numbers”:[0,1,15,0,23,15,0,0,0,0,2,19]

I want to make a sensor that adds those up into a single number. i.e. “totalNumbers”:75

Can someone please help me with this?
