Help required for json formatted data please

Hi,
I need to send json formatted data to the cloud and set up a web hook to send it on to our online server. (Similar to thingspeak). What I have is vehicles with data records. I want to send a bunch of data records periodically from each vehicle.

I am new to Json and have use the Arduino json object to generate the string below.

The topic is “bgLog” (which I can use the HologramCloud.attachTopic). I need each packet to have a number of the same type and size of record and a vehicle ID (timedate stamp plus raw data) so I can place the data for each vehicle correctly on our server once it arrives from the web hook.

Is the string below correct? (Vehicle ID is VH685).

Also, is there a simple example how to set up custom web hook for a json array like this?

{“VH685”:[“2017/07/06,09:30:56,1,3412,2”,“2017/07/06,09:30:56,1,8657,2”]}

JSON looks ok.

We have some documentation on that kind of stuff https://hologram.io/docs/guide/cloud/routing-rules/#app-types

Are you just trying the pass the data straight through to another service or do you need to manipulate it first?
