Insert the current time your Zap runs into a field

{{zap_meta_human_now}}

I have gotten full access to the JSON array through the following steps:

1) Catch a raw webhook

2) Send the webhook data to a Code by Zapier step

3) Start with the following code and output the values you want to use.

var obj = {},

data = JSON.parse(inputData.data); //Data will now function like a json object



//Pull out your values

obj.value = data.user_column_data[1].string_value

return obj;
