    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.

      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?

    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.

    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.

    When developing software, if you opt to create an SDK initially, design it in a way that allows for its use across multiple applications. An SDK is essentially a language-specific wrapper for APIs, so building distinct SDKs for similar applications is simply redundant. Additionally, remember that APIs are not constrained by language. Thank you.

    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.

      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.

    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.

  • @electricz3045
    @electricz3045 Год назад +2

    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")

  • @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.

    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.

      Sorry, but there seems to be some confusion here...
      An sdk is typically a KIT for fx DirectX and the likes. Its purpose to give you a toolset on the box. It's also often including tools for advanced debugging like the Windows SDK. You work with a specific product to create something on that platform.
      Api is an interface where for you ask a system or part of a system through a defined protocol to do some task for you.
      Api exposes something through a specific paradigm whereas SDK's contains more than just a facade. That's more like lego.
      REST is really a bad example, if we're being academic here. Cause we're talking about a very old paradigme that has been popularized. So, when people talk about Apis today, we tend to think HTTP, and not the likes of a C header file.
      It's a matter of level of technology
      Oh on a side note: I find it weird that this videos discusses a topic with no reference to C or C++ where these terms came to life and back in the hayday set many standards including this topic.

    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

    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.

    I am new to APIs and trying to get myself around it so my question may be silly. But why is the POST method used in this case and not GET? I mean we do not try to push data to the external service, right? We only want to get information out of it, don't we?
