My aim is to select some text from a web page, start a google chrome extension and give the text to a google cloud api (Natural Language API) in my case.
I want to do some sentimental analysis and then get back the result to mark/ highlight positive sentences in green and negative ones in red.
I am new to this and do not know how to start.
The extension consists of manifest, popup etc. How should I call an API from there that does Natural Language Processing?
Should I create a Google Cloud Application with an API_KEY to call? In that case I would have to upload my credentials right?
Sorry sounds a bit confusing I know but I just don't know how I can bring this 2 things together an would be more than happy about any help
The best way to authenticate your app will depend on the specific needs and use cases of your application. You can see an overview of all the different methods here.
If you are not planning on identifying users nor on using a back end server that handles authenticating (as I assume to be your case), the best option would indeed be to use API keys. They do not identify the user, but are enough for the Natural Language APIs.
To do this you will need to create an API key for the services you want and add the necessary restrictions to make the key as secure as possible. Detailed instructions on how to do this and how to use the key in a url can be found here.
The API call could be made from within the Chrome extension with any JavaScript method capable of performing POST requests. For example using XMLHttpRequest or the Fetch API. You can find an example of the parameters that need to be included in the request here.
You may run into CORS issues when making the request directly from the extension. I recommend reading this answer, where a couple of workarounds for these issues are suggested.

I am wanting to pull all users in my company dropbox and then check to see if their accounts have MFA enabled. I read over the documentation for Dropbox api but did not see anything stand out where this was possible.
It's very sad to realize that a popular platform such as Dropbox doesn't expose A LOT of basic features through its API (and the SDK itself is far from being OK, compared to G-Suite). Anyway, there are two hacky methods you can use in order to pull out that information (with some limitations).
First method:
By analyzing the team events using team_members_list() you can filter out tfa_change_status_details events. When new_value=TfaConfiguration('[sms|other]', None) is specified - 2FA is enabled.
The information I found out that can be retrieved using this method is:
has_2fa - whether 2FA was ever configured.
is_tfa_enabled - whether 2FA is currently enabled.
tfa_type - whether 2FA is by SMS or by app.
However, keep in mind that you have to track changes constantly and also keep in mind that Dropbox saves team events for only two years.
Second method:
Using the front-end dashboard API this information can be retrieved (I can't remember the API name, I think that it is /2/get_multifactor and inside you'd find some information about its status and the organizational policy regarding 2FA). However, to use the front-end dashboard API (which is totally undocumented) you'd need to simulate a successful login (and correctly use the lid and jar cookies) and you'd also need to bypass the random captcha that appears when you abuse the service with too many requests.
To be honest, Dropbox's API is weak, neglected, and ugly. I wish I never had to use it. Anyway, I would recommend using the first method and pray for a significant update to the API
No, unfortunately the Dropbox API doesn't expose this. We'll consider it a feature request.
There's a feature request open for this one (https://www.dropboxforum.com/t5/Dropbox-API-Support-Feedback/MFA-status-for-users/m-p/468564#M23886). But I wouldn't hold your breath, as #Aviv mentioned the Dropbox API seems surprisingly neglected at the moment.
My app is a Personal Assistant who's main job is to redirect the user to something that complies with his/her wishes. I realize, for example that AllRecipies.com has no API. My question is that can I, say open the browser app with the url as
http://allrecipes.com/search/results/?wt=QUERY>&sort=re.
Is this considered as using their API? Not just AllRecipies, but numerous other such services. If I am using this method, then do I have to request API key, etc? I am not retrieving anything. I am simply redirecting the user to their page with the query pre-written. Does this require all the licensing fees, API Key, etc?
Do I have to agree to this fees(If they ask), Request API Key, etc?
With the particular URL in question, it is simply an HTML web server URL, rather than a web API, as such. You can still get data out of it, but you'd have to parse the HTML yourself to extract what you want from the HTML response.
They may have an API that you can use to access data more directly as JSON, XML, etc, but you'll have to look into that yourself. And you will possibly require an API key to access it. But perhaps not, if it's publicly available and they don't care how many calls they get to it by anonymous users.
You may find this resource useful. It contains a lot of open APIs and code snippets to access them: http://www.programmableweb.com/
If you are simply trying to hit a URL or directing a user to this particular URL which you already know and is static meaning you always hit the same url without change in parameters, then this is not considered an API call and will not be requiring any API key.
However, if they have some APIs exposed, you will need to go through their documentation and using this API most likely requires the use of an API key(alhough this might not be true always). Usually, most platforms have a bunch of APIs available for different scenarios and these are called based on user specific parameters and requirements.
How to get the API key for the authentication purposes for posting the request to get the email previews using Litmus?
There are actually a few different Litmus Preview APIs to cater to different use cases. We're in the process of simplifying this, partly in the hope of making the experience for a new API user a little more obvious.
If you reach out to hello#litmus.com we'll direct you to the appropriate API version and how to obtain your key.
I have a website that revolves around transactions between two users. Each user needs to agree to the same terms. If I want an API so other websites can implement this into their own website, then I want to make sure that the other websites cannot mess with the process by including more fields in between or things that are irrelevant to my application. Is this possible?
If I was to implement such a thing, I would allow other websites to use tokens/URLs/widgets that would link them to my website. So, for example, website X wants to use my service to agree user A and B on the same terms. Their page will have an embedded form/frame which would be generated from my website and user B will also receive an email with link to my website's page (or a page of website X with a form/frame generated from my server).
Consider how different sites use eBay to enable users to pay. You buy everything on the site but when you are paying, either you are taken to ebay page and come back after payment, or the website has a small form/frame that is directly linked to ebay.
But this is my solution, one way of doing it. Hope this helps.
It depends on how your API is implemented. It takes considerably more work, thought, and engineering to build an API that can literally take any kind of data or to build an API that can take additional, named, key/value pairs as fields.
If you have implemented your API in this manner, then it's quite possible that users of this API could use it to extend functionality or build something slightly different by passing in additional data.
However, if your API is built to where specific values must be passed and these fields are required, then it becomes much more difficult for your API to be used in a manner that differs from what you originally intended.
For example, Google has many different API's for different purposes, and each API has a very specific number of required parameters that a developer must use in order to make a successful HTTP request. While the goal of these API's are to allow developers to extend functionality, they do allow access to only very specific pieces of data.
Lastly, you can use authentication to prevent unauthorized access to your API. The specific implementation details depend largely on the platform you're working with as well as how the API will be used. For instance, if users must login to use services provided by your API, then a form of OAuth may suffice. However, if other servers will consume your API, then the authorization will have to take place in the HTTP headers.

What things should a developer designing and implementing an API for a community based website know before starting the heavy coding? There are a bunch of APIs out there like Twitter API, Facebook API, Flickr API, etc which are all good examples. But how would you build your own API?
What technologies would you use? I think it's a good idea to use REST-like interface so that the API is accessible from different platforms/clients/browsers/command line tools (like curl). Am I right? I know that all the principles of web development should be met like caching, availability, scalability, security, protection against potential DOS attacks, validation, etc. And when it comes to APIs some of the most important things are backward compatibility and documentation. Am I missing something?
On the other hand, thinking from user's point of view (I mean the developer who is going to use your API), what would you look for in an API? Good documentation? Lots of code samples?
This question was inspired by Joel Coehoorn's question "What should a developer know before building a public web site?".
This question is a community wiki, so I hope you will help me put in one place all the things that should be addressed when building an API for a community based website.
If you really want to define a REST api, then do the following:
forget all technology issues other than HTTP and media types.
Identify the major use cases where a client will interact with the API
Write client code that perform those "use cases" against a hypothetical HTTP server. The only information that client should start with is the response from a GET request to the root API url. The client should identify the media-type of the response from the HTTP content-type header and it should parse the response. That response should contain links to other resources that allow the client to perform all of the APIs required operations.
When creating a REST api it is easier to think of it as a "user interface" for a machine rather than exposing an object model or process model. Imagine the machine navigating the api programmatically by retrieving a response, following a link, processing the response and following the next link. The client should never construct a URL based on its knowledge of how the server organizes resources.
How those links are formatted and identified is critical. The most important decision you will make in defining a REST API is your choice of media types. You either need to find standard ways of representing that link information (think Atom, microformats, atom link-relations, Html5 link relations) or if you have specialized needs and you don't need really wide reach to many clients, then you could create your own media-types.
Document how those media types are structured and what links/link-relations they may contain. Specific information about media types is critical to the client. Having a server return Content-Type:application/xml is useless to a client if it wants to do anything more than parse the response. The client cannot know what is contained in a response of type application/xml. Some people do believe you can use XML schema to define this but there are several disadvantages to this and it violates the REST "self-descriptive message" constraint.
Remember that what the URL looks like has absolutely no bearing on how the client should operate. The only exception to this, is that a media type may specify the use of templated URIs and may define parameters of those templates. The structure of the URL will become significant when it comes to choosing a server side framework. The server controls the URL structure, the client should not care. However, do not let the server side framework dictate how the client interacts with the API and be very cautious about choosing a framework that requires you to change your API. HTTP should be the only constraint regarding the client/server interaction.
