I want to search response/request through keywords written in payload.
It's quite difficult to press and check every request.
Please let me know if there is a good way.
I want to search with any keyword that I cricled...

I am trying to scrape the "Amenities and More" portion of the Yelp, and came across this very helpful answer that explains the best way to do it (BeautifulSoup web scraping for a webpage where information is obtained after clicking a button).
The problem is, I am unsure how the person who posted the answer (Martin Evans) knew that typing "GetBusinessAttributes" and "GetBizPageProperties" would tell Yelp to return the requested data. I used my network dev tools to check what data was being requested when I visited https://www.yelp.com/biz/ziggis-coffee-longmont, but found no mention of "GetBusinessAttributes" or "GetBizPageProperties".
Can someone explain how he knew that sending "GetBusinessAttributes" and "GetBizPageProperties" would return the desired data?
I remember coming across APIs/URLs like: http://www.testsite.com/students.json, which returns a JSON response, and read somewhere that you can find it via e.g. Chrome dev tool under Network tab.
Where/how can I find the JSON APIs/URLs? Would ultimately use requests to fetch the JSON.
The best place to find out about a JSON-based API is the documentation provided by API's maintainer. Typically, maintainers who would like their API to be consumed by clients provide documentation. Sometimes, they build a navigable API where responses have http links to other resources of their API and do not provide an explicit documentation. If they do so, that could be called as implicit documentation.
Networks tab in a web browser's developers' tools provides a way to capture network traffic going in and out of the browser. If a website makes any asynchronous http request, that will be captured and shown here. Again depending on the design and strategy of the website maker, this could be a JSON based response coming from a URL or a HTML or any other type. Content-Type header hints at the type of response. You can use this cue as well to see if the content of the response is application/json. Thus, obtaaining a url that you can use in your scripts.
What you are trying to do here is observing a website's network traffic from your browser and are trying to see if there is any link that brings you a JSON based response instead of HTML. So, that you can use a JSON parser instead of a HTML parser. Possibly, because HTML parsers are slow.
The Answer to your specific question is, if you get lucky you might find a link that serves a JSON response. If not, you might wanna fall back on HTML parsing.
I am trying to get started with REST API calls by seeing how to format the API calls using a browser. Most examples I have found online use SDKs or just return all fields for a request.
For example, I am trying to use the Soundcloud API to view track information.
To start, I've made a simple request in the browser as follows http://api.soundcloud.com/tracks/13158665.json?client_id=31a9f4a3314c219bd5c79393a8a569ec which returns a bunch of info about the track in JSON format
(e.g. {"kind":"track","id":13158665,"created_at":"2011/04/06 15:37:43 ...})
Is it possible to only to get returned the "created_at" value using the browser? I apologize if this question is basic, but I don't know what keywords to search online. Links to basic guides would be nice, although I would prefer to stay out of using a specific SDK for the time being.
In fact, it's really hard to answer such question since it depends on the Web APIs. I mean if the API supports to return only a subset of fields, you could but if not, you will receive all the content. From what I saw on the documentation, it's not possible. The filters only allow you to get a subset of elements and not control the list of returned fields within elements.
Notice that you have a great application to execute HTTP requests (and also REST) in Chrome: Postman. This allows to execute all HTTP methods and not only GET ones and controls the headers and sent content and also see what is received back.
If you use Firefox, Firebug provides a similar thing.
To finish, you could have a look at this link to find out hints about the way Web APIs work and are designed: https://templth.wordpress.com/2014/12/15/designing-a-web-api/.
Hope it helps you and I answered you question,

Straight from the browser bar you can utilize REST endpoints that respond to a GET message. That is what you are doing when you hit that URI, you are sending an HTTP GET message to that server and it is sending back a JSON.
You are not always guaranteed a JSON, or anything when hitting a known REST endpoint. What each endpoint returns when hit with a GET is specific to how it was built. In that case, it is built to return a JSON, but some may return an HTML page. In my personal experience, most endpoints that utilize JSON returns expect you to process that object in a computer fashion and don't give you a lot of options to get a specific field of the JSON. Here is a good link on how to process JSON utilizing JavaScript.
You can utilize REST clients (such as the Advanced REST Client for Chrome) to craft HTTP POST and PUT if a specific REST endpoint has the functionality built in to receive data and do something with it. For example, a lot of wiki style REST endpoints will allow you to create a page with a specifically crafted HTTP POST with either specific header information, URI parameters or a JSON as part of it.
you can install DHC client app in your chrome and send request like put or get
I think this is how should it work: I record the HTTP activity while browsing my website online. Then, When running my website's HTML offline, no network activity is made. And when a request is made, a response is retrieved from the recorded log.
I need to know how can I make this.
I think this tool is little near from what I want to do. But, unfortunately I don't know how to use it for my case.
The fact that you tagged this post with Fiddler suggests that you know that Fiddler can already do this using the AutoResponder tab. You may wish to update your question to explain why you don't want to do that.
Say I go to google.com and search for "Klaus Harmony". The first result is a Wikipedia page. If I open the network tab and click "preserve log", so that the requests won't be cleared upon navigation, I see 2 things:
A POST request, with the status (ping)
A GET request which carries the HTTP Referrer of "http://google.com"
My questions are:
What are they trying to accomplish here, especially with that strange first request?
How are they changing the HTTP Referrer?
I'd say its to check if the site still works or should you see see the last crawled version of the page if the ping fails, another thing might be for google analytics purposes
if you search at google.com, google.com is your referrer, there is no need to change anything. You can modify it to omit the ?Q=== part by proper meta, you can read here: http://wiki.whatwg.org/wiki/Meta_referrer
