Changing the Response Body Format
When receiving a JSON response, I change the format of the response to JSON to make it easier to analyze. However, it resets to HTML every time I receive a new response. I wish it would stay JSON until I manually switch it so that I can examine responses faster and more efficiently. More on community.postman.com

JSON is a text-based data format following JavaScript object syntax. It represents structured data as a string, which is useful when you want to transmit data across a network. Even though it closely resembles JavaScript object literal syntax, it can be used independently from JavaScript.

Two things:
1) You're json encoding an object with a single string but you need to encode an object with an array.
2) You're using http_build_query which will urlencode the array arguments and break the JSON structure.
Do this:
$del = array("delete_list" => [ "8bca1d69c82d939d65ef8ea9a7947bbe" ]);
$j = json_encode(
apiToken = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$httpHeadersArray = Array();
$httpHeadersArray[] = 'Authorization: key='.$apiToken;
$httpHeadersArray[] = 'Content-Type: application/json';
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $curlUrl);
#curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, $j);
curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeadersArray);
$res = curl_exec($ch);
echo "<pre>";
print_r($res);
echo "</pre>";

r/learnjavascript on Reddit: Can someone please explain JSON to me?
November 24, 2023 -
I've never worked with any DB or back-end, etc stuff, but I am in need of some sort of data storage. I'm working on a javascript application that will only be run on my pc, offline, and I need to be able to save information. I don't want to rely on localStorage because if the browser history is wiped then all the data goes with it.
While searching for a way to collect and store info, I read about JSON, and it sounded like what I was looking for--and yet I've spent the last 4 hours watching tutorials and so far all I know about it is it's fching JS. I sat through a 12 minute video where all the guy did was write out an object in json and then copy and paste into a js file and said "now you know how to use json in all your future projects" ๐ like what in ACTUAL fk. You could have just WROTE that in js. What's the point of JSON? Everything I've seen or read is practically just the same as this video.
DOES json collect and store data?
Like, if I put an input form in my app, and type a name and hit submit, can I make that Input hardcode into the json file to be saved forevermore and called upon when I needed in this app? Because that's what I need. Any explanation or help on this would be GREATLY appreciated.

JSON is used to exchange data between your data store and your application through an API. It doesnโt do much by itself. You can think of a JSON file as a text file with a specific format. The importance of JSON comes from how itโs used. Youโll usually make an API call to request data from an API, and the API returns the information in JSON format. Before JSON we used XML (the X in AJaX). Before XML weโd just use csv or flat files (txt). You can create a JSON file and read data from it in your application but you usually create a backend for the application to make GET and POST requests to read and change the data.

When your JSON is validated with JSONLint this is the result:
Error: Parse error on line 1:
{ taco: { name: "",
--^
Expecting 'STRING', '}', got 'undefined'
The object keys should be strings. This is valid JSON:
{
"taco": {
"name": "",
"price": "",
"photo_url": ""
}
}
