 If you do not provide any requestId it will be autogenerated.
-The maximum for the timeout should be 35 seconds as FaaS functions time out after 30 seconds.
+The maximum for the timeout should be 40 seconds, it will be internally split up in 10 seconds of connection timeout (40*0.25) and 30 seconds of request timeout (40*0.75) as FaaS functions time out after 30 seconds.
