i want the travelDistance, travelDuration and travelDurationTraffic

but if i do
rule:

var String json = sendHttpGetRequest(“http://dev.virtualearth.net/REST/V1/Routes/Driving?o=json&wp.0=london&wp.1=leeds&avoid=minimizeTolls&optmz=timeWithTraffic&routeAttributes=routeSummariesOnly&key=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaL”)

var String travelDistance1 = transform(“JSONPATH”, “$.travelDuration”, json)

i’am getting null

I think, you will have to use

transform("JSONPATH", "$.resourceSets[0].resources[0].travelDuration", json)

@Udo_Hartmann Thanx a lot
