ls_error = ln_json.parse('[{"route":"Transaction","service_status":"Active","balance":82,"validity":"2022-08-11T18:30:00.000Z"},{"route":"Promotional","service_status":"Active","balance":100,"validity":"2022-12-30T18:30:00.000Z"}]')
if ls_error = "" then
	if ln_json.isarray() then
		any la_array[]
		la_array[] = ln_json.getarray()
		messagebox("array length:", string( upperbound( la_array[] ) ) )
		ln_json.retrieve("1/route", ref la_data)
		string ls_route
		ls_route = la_data
		messagebox("1st route:", ls_route)
	end if
end if

int li_start, li_end
String ls_error, ls_response, ls_value
any la_data
any la_value

ln_json = create json
ls_response = '{"contents": [{"id" : "1", "name" : "one"},{ "id" : "2", "name" : "Two"}]}'
