Hi, I am trying to fetch data from a API using "get_webpage". The website respods with a json array. No I am not able to use "cut document" to get specific values from the response by writing json queries.
I use the query : $.result.accountStatistics[0].

Seems it is expecting a double dot, this works :
$.result.accountStatistics[0]..
summary.totalInteractionCount As an alternative you can also just cut on the accountStatistics and then use a json to data component as below example, this makes it a bit more easy to work with the full set of data.
