What is the best way of getting information from an API?
In ClojureScript you can use Ajax GET requests to connect to an API.
For my exponent app, I want to have a button that when pressed, it connects to a website, say Google (doesn't have to be, just an example), and then simply returns the data.
I also need authentication for these requests so how would I add that as well?
In react native you can use fetch, how would I use this in ClojureScript?
Any help would be much appreciated. Thanks.
Actually it's really super simple.
(js/fetch your-arguments)
Just remember that you can get acces to js functions via js/. And don't forget to pass js data-structures to function. I'm talking about clj->js function.

I'm using an API to receive information from a server. I'm authorising using a token. I can query using curl or various api testers online. But now I'm trying to learn how to implement (and request) the results in practice.
I'd like to query, parse and display the json result on a web page (preferably a Wordpress site).
So I need to make a get request, authorise myself using my token, and receive the result and then display it in a nice way.
How do I do that?
This is a vague question, not really sure if you are making requests from just one side but you have 2 options, albeit one being better than the other.
You can create add multiple functions inside your themes function.php file to extend its capabilities but again these are limited to only the theme you are using.
I would recommend that you build a plugin, this will give you the flexibility to use both JS and PHP to do whatever you need to do. With this method you can create a shortcode to display the results from your API query.
You will need to learn to use the Wordpress function wp_remote_get() to perform external API calls.
Here is a tutorial with more information:

In a restful API, POST should be used to create, and GET should be used to read.
Sometimes, for security reasons, you can't pass sensitive variables in the URI. For example, if you have an /accounts API that requires you to pass "accountNumber". If your security team won't let you put that in the URI, then you have to use the POST method instead of the GET method to service the "read" operation, and you can then provide the account number in the request body.
That brings me to my question: If you've used up the POST method to service a read operation, how do you service the "create" operation of the same API?
"/accounts/create" wouldn't be advised because your APIs should be nouns, not verbs. It doesn't seem right to use up a different HTTP method like PUT. This issue has to come up a lot so I'm curious what people are doing to get around it?
If you're using POST for this, you are not building a RESTful service. The way I see this, you have 2 options:
Accept this, and build a more RPC-like system.
Change the id's in your application so that they are not a security risk. If knowing an id is a problem, consider using something else.
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'm making a Twitter account statistics program that reads tweets, retweet counts, and favorite counts. I could attempt to read the user's Twitter account URL line by line and parse the information from there, but I was wondering if there was a public API or part of Twitter that just spits out the raw data without formatting it all pretty for web browsers? Not only would this be more efficient in the program, but would also be much neater.
It seems as though API 1.1 uses JSON to fetch data, but I need to make a developer account and create unique identifiers in order to access such data. Is it worth it? Is there some sort of alternative that would be faster and easier?
All API calls to Twitter now require OAuth authentication, so there is unfortunately no way around signing up for a developer account and creating an app. It's not even possible to use a service that makes the requests on your behalf, as this is re-syndication which is forbidden by Twitter's API terms, so you need to make the calls yourself.
I've got an android and iphone app that both get the required data from a webserver. The data is sent via json to the client. Using this setup other people might simply retrieve the url the app is calling and this way could make use of the data that I gather with my scripts on the server. To make it short: I don't want that :)
My idea is to make the json unreadable for example by encrypting it. This would make it a little harder to retrieve the information since this way some who would like to use my service would had to decompile the app an lookup any decryption stuff I had implemented.
Therefore two questions:
Do there exist some libraries that already offer such a functionality (Server side is Java)?
Does anyone of you have any other suggestions how I could protect my api from unwanted guests?
Thanks in advance :)
I think the options available would be...
to lock down the API to Authorized/Authenticated users.
Using BSON to obfuscate the data.
You could always use oAuth to allow the users to authenticate based on an account they already have: Facebook, Twitter, Google etc.
