Retrieving URLQueryString elements?

Questions
1

I have a URLQueryString that WL has interpreted per the following screenshot:

…which appears to be a set of Rules. I can’t figure out how to retrieve the value of “checkin” from this input and then ImportString it as RawJSON to create a Dataset because WL keeps complaining that it’s not a String.

I’m not entirely clear on what you want, but interpreting “how to retrieve the value of ‘checkin’” literally, you can do this:

"checkin" /. j

or

Query["checkin"][j]

So, to get the json,

ImportString[Query["checkin"][j], "RawJSON"]

Also, it would help if you formatted your code to be copy-paste-able.

Correction to your answer: Should be Query["checkin"][k] … why Wolfram couldn’t make this consistent is beyond me (with Dataset and Association I’d use k[["checkin"]]).

Um…where does the k come from?

Oops, my bad; the script I’m implementing this in uses j as the raw query text while k is the Interpreter value. Forgot I had copied this from my testbed. :slight_smile:
