API vs. SDK: What's the difference?

[@richa9719]

An SDK is just a pre-packages set of code (for a specific language) that you don’t have to write yourself. Sometimes free and sometimes you have to,purchase them. In the case of this video, he is suggesting a “API-Interaction” SDK a developer would use. There are all sorts of other SDK’s out there including things like an SDK to simplify building a User Interface.

[@ulicqueldromal]

What you describe sounds more like a framework to me. Isn't an sdk (software development kit) something you use during the development rather than during actual runtime? Like a debugger etc. If I'm wrong (which is totally possible), could you tell me where you would draw the line between framework and sdk?

[@tresaidh3y90]

Summary : - API : enables a system to communicate with another (without having to understand the complexity of the other system) - SDK : enables you to use APIs easily

[@janglestick]

well ... SDK's are actually code. It's actually instantiated, rather than being a protocol.

1 Quick Question. Can a API not work properly without an appropriate SDK and vice-versa ?

[@hachiman_1]

@@bibekanandabhattacharjee952 My understanding is that sdk make it easier and faster to implement the api communication rather than writing code from scratch as it contains already all the methods needed to make api calls so we can just call the methods instead of writing the entire implementation. (Without reinventing the wheel)

[@PoolarityChannel]

Prior to 2000 and there is a period of overlap, API was synonymous with function calls to external libraries exposed by other modules. It could be local, in memory, inter-process or remote libraries (or set of libraries SDK), whether it was binary or textual. API's around 2000 became synonymous with HTTP SOAP Web Services, and circa 2012 became synonymous with REST Web Services.

[@jamzbraz]

I'm glad to see this comment cuz what's being discussed in the video is a Web API instead of a regular API. Nobody I work with seems to understand there's a difference there.

[@mytestchannel2-e1f]

API is also the library of interfaces to a desktop application or program. For example, you can integrate a program to Excel by using its COM API Interface. API is basic, it's only an interface. An SDK is more complete as it can have library API interfaces AND Tools to work with a specific technology. For example, if you want to develop mobile apps from Windows, you will need an SDK for a mobile OS, which is a complete set of tools to compile the code to Native Mobile OS, a debugger, an IDE, etc. etc.

[@electricz3045]

I save you some time here: API is if you make the requests yiursefl to an url to get, post, put etc. json data. SDK is a sort of module written by the service provider which contains functions you can use to complete your task. Example would be: upload_image("cat.png")

[@chrisinhim]

I understand now what all this means, but sometimes you are just looking for simple definitions: API is a URL that does something (retrieve info, change something or perform an action). SDK is a file or files which have libraries that developers download and use in their proyects. Then it comes everything else that you brilliantly explained.

[@rtothec1234]

Without SDKs we would need to send API requests using low level HTTP commands in whatever language we use. For example: Wanna talk to the Stripe API to get customer info using PHP? Without an SDK you probably need Guzzle HTTP library to send several requests to the /customer/ endpoints while needing to pass authentication credentials each and every time in your code. With their PHP SDK you aunthenticate once within your scripts and use the Customer object to get customer related data. SDKs facilitate using an API but are not the API and are not guaranteed be offered by the service/company that published the API. On the other hand, consuming the API using lower level commands offers us more control depending on how deep the SDK was implemented or not. I highly recommend checking out Stripe’s APIs and SDK documentation to get a good example of amazing implementation.

[@ricky08454]

Perfect. Was struggling with these terms. Helped me get a basic idea to build on.

[@karianpour]

The down side of the SDK is its size. It has many funcrionality that one app might not use, also as SDK should be consistent over time, it should have the older versions which make them even larger over time. Also, as they run on our thread, they could have security issues, as well as malwares. It is better to make a good document for API vs an SDK. But big companies like to creare SDK to abscure data from developer. So never use an SDK unless it is open source.

[@OEThe11]

Very Interesting. And here I thought SDK's was a great Idea.

[@BooleanDev]

worth noting that if the language has tree shaking, sdk size is not an issue

The advantage of SDK is just to avoid handeling api requests and response , but in reality SDK will not reduce the extra code form application . In simple word SDK is a sinthetic sugar over API

[@bsummer]

[@superheaton]

That's the idea. It should always be the guiding principles of good software. It's also great that the api or design when they are easy for the layperson to dive into the subject. Yes there is still a learning curve. If you look at search engines you dont ever had to think about issues about ranking or api or syntaxes almost never. Similarly, difficult concepts should be enjoyed by everyone. So there is a lot of work still. Glad you're enjoying it

[@Euler123-h8n]

Some misconceptions on this video: 1. API is not synonymous of REST, API it’s about interface exposition. 2. There are kinds of APIs: Communications API: Like Rest; Systems API: Like Windows API, Programming Languages API: Like JAVA APIs… and so forth 3. SOAP it’s a specification for a messaging protocol, not an API effectively. His implementation can be. I really don’t like to see people using the words API and REST indistinctly…

[@victortang94]

[@angeldimitrov1353]

Great video, I think this helps remind us of what an API ‘actually’ is…I personally tend to use the term API when I should really be saying ‘SDK’. I think another important concept to mention is that an API requires the logic to be hosted on 3rd party hardware, whereas SDK entails assemblies that you absorb as local references to your project and publish along with your build.

[@Potzakv20]

What is the difference between a SDK and a package then?

[@daneast]

TLDR: an API is a specification. An SDK is an actual set of libraries, code and / or tools. There is usually overlap between the two.

They're both in the name. API, Application Programming...Interface - a way of programming an application. An application is already built and is already running. An SDK, Software Development...Kit. A set of tools (a kit) to develop software. This is independent from the application (a prebuilt binary). It's tools that you use to build a binary that does a specific thing. They usually consist if multiple APIs.

The main difficulties of existing API multilevel systems are: 1.The difficulty of porting a program code from one API interface to another. 2.Loss of functionality upon jumping from lower layer to higher.

The term API has been in use since the 1980s. Then it referred to callable functions to allow programmers to interact with the program product such as IBM CICS. In the 1990s we started to use the term with intra company systems. The customer information system at the bank where I worked had no screens of its own. Every action was performed by API calls. It is wrong to say that API calls are standardised, The same API could be called using XML (SOAP when it became popular bespoke initially) over HTTP or MQ or natively from a message switch. There is no requirement to use JSON or XML. It appears that the term API has been hijacked to mean REST, but that is only one implementation

An API is the protocal used to comumicate with another program, regardless of its loaction. Not all APIs, out side of networking, are standardized and some on networks are not either. I've worked with several different APIs. Unfortunately, some (think hardware) did not provide an SDK, so I had to write my own. An SDK is basically software/code that translates your requests and commands into the protocol required to communicate. In this way the programmer doesn not need to know the protocal to communicate with the API. An SDK is usualy a library integrated into your software, but can also just be a module in your application.
