Help to handle API 404 error

Hello Wapplers,

I’m try to handle external API call when there is 404 error.
I have Condition after API call api.resposne==200 which handle good when external API return 200, but when there is 404 error I see this message in output: {"errorCode":404,"message":"Device not found for specified identifier","activityId":"8f1925a7-dc7e-4d6e-bd82-955714eb0012"}

And errors in WebLogs:

  server-connect:server Got error? '{"errorCode":404,"message":"Device not found for specified identifier","activityId":"b7b1c30a-70b0-426c-8360-94593a182025"}' +13s

How then to design handle when 404 error appears?
