"API enables communication between different applications" Thank you for being the first person to give an understandable explanation. I kept running into video after video giving vague descriptions of what an API does by using the Waiter and Chef analogy, without ever explaining they were representing applications.
A much simpler way to understand what an API is, imagine you login to your Bank and do all the activities there - wire funds to another account, transfer, view balances, search a transaction by a specific amount or date, etc. This is User Interface, or UI. Now imagine you are a big company and have hundreds or thousands of daily Bank transactions. Inputting, handling and managing them manually would be a herculean task, very time consuming, would need a lot of people to manage these tasks manually, hence costly, as well as will be prone to error when you want to bring these bank transactions to your company's accounting ledger, like an ERP system. So, to facilitate this, most Banks provide secure digital interface with exactly same feature as you can perform via a UI. This digital feature is what is called an API. More appropriately, we will say that such and such features are implemented or exposed by a specific application (in our example the Bank) via APIs.
You put lot information in a very small video that is not an easy task for someone. It requires lot of skills and experience to make this kind of clear and crystal explanation about one confusion topic so anybody could understand in an easy manner. Thanks a lot for sharing very beautiful information. God may increase your knowledge
This is one topic which has so much information available on the internet including on youtube and yet i find myself continuing to come back to search for it again and again because something stays amiss. Thank you for this wonderful video and must I say that your style of speaking is very soothing and genuine. No flamboyance, only pure knowledge. You keep it real. Thanks.
You are the best teacher I am looking for these many years... Subscribed ur channel in the first video itself and am gonna watch all ur videos without miss from scratch... Hats off Sir.
Mr. Pal, thanks for all you do.. What a nice tutorial. In fact, the best tutorial I've seen on APIs. I've been stuck for some weeks now because I wasn't understanding how and what to begin with on Payment Integration but with this tutorial, you have explained so much to me. Thank you.
Very simple presentation and perfect example as well. Subscribed ! Also an API maybe used if you don't want to create a functionality from scratch because it already exists (LOGIN for example) so you might want to use OAuth or some other login service that already exists and handles security protocols, etc for you without having to worry about encryption, data security , etc. So using an API can save you some time as a developer and complications in your project. :)
Well and carefully explained tutorial. I like your approach man! You definently deserve more subscribers. Thank you i was so confused with this whole API's configurations and never really understood what are they and what are they used for but thanks to people like you now i have a general idea. Now its time to implement them :) Keep girnding and happy coding ! :)
You are a fantastic teacher and you are doing an amazing deed with free accessibility to your content. Appreciate it. 🙏🏼 will definately recommend and share your video to all newbies who are trying to get into IT.
@RaghavPal Its very difficult to explain correct thing in a simple way and you are really very good in it. The question what is an API is difficult to explain but the way you explained it is awesome. I can explain it very easily to anybody else now.
@@RaghavPal You are welcome Raghav. A quick question - as I am a PL/SQL developer, how can I use Webservices or APIs in Oracle? if you have the know-how, where is the starting point for me or where should I begin? Please let me know.
This is a very good video to understand API, In fact, the best so far. This is a short but straight to the point video while extinguishing any confusion about what API is.
If you used indigo website directly does it mean you have not used any API? Relating this to the restaurant analogy, the user makes a request via a browser to the website. So is that an API there too?
Hi Raj, today most of the communication happen through API calls. Even if you go to Indigo website, they may also be using api at the backend. As they are faster, efficient, secure.
Hey Raghav.. Loved your videos.. It would be great if you could make series of videos for API testing. But to be honest your videos and way of teaching and showing real time examples .. great!!
You are awesome, you are given a lot of information about API, which is a very simple way and just within 8 minutes. Thanks for the simple API definition.
Your description implies that “make my trip” is an API between you and the multiple airlines. But my interpretation is that there are 2 layers of APIs here. The web page is an API between you and Make my trip, and there is another API between make my trip and each airline, correct?
Hello, I have a question. We are using a third-party SaaS provider that has a large amount of data we need to use in our proprietary application. They do have the means to extract the data via API, etc. We use the data in our proprietary application to create charts, etc. As it is a large amount of data we need to make use of, I am not sure if doing a GET request each time to fetch the data is ideal. Do you suggest pulling the data locally into our database and then retrieving the data from there? Also, do we use ETL for this? I am kind of new to ETL as well. What is the best approach?
Hi Nate, here we need to check the reliability of the systems and performance, if you run a GET api each time, how reliable is that, what is the turn around time, etc. In case it meets your expectation you can use this way. Pulling the data into your local is an option. In case the data is not dynamic and does not change real time, you can check for the feasibility of this option
Hi Pavan SOAP and REST are two different types of web service APIs that are commonly used in software development. Here are some ways to identify them: SOAP API: WSDL: SOAP APIs typically use the Web Services Description Language (WSDL) to describe the service and its methods. WSDL is an XML-based language used to describe the functionality of a web service. You can identify a SOAP API by looking for a WSDL file or a URL that ends in ".wsdl". XML messages: SOAP APIs use XML messages to send and receive data. SOAP messages are typically more structured and have a strict schema defined in the WSDL file. SOAP headers: SOAP messages also contain SOAP headers that provide additional information about the message, such as authentication and encryption details. Example: Here is an example of a SOAP API request to get weather information:
New York United States
REST API: HTTP methods: REST APIs typically use HTTP methods such as GET, POST, PUT, and DELETE to interact with resources. You can identify a REST API by looking for URLs that contain the HTTP method name. JSON or XML payloads: REST APIs can use either JSON or XML payloads to send and receive data. JSON is becoming the more popular choice for REST APIs as it is more lightweight and easier to parse. Stateless: REST APIs are designed to be stateless, meaning that each request should contain all the information needed to complete the request. Example: Here is an example of a REST API request to get weather information: GET api.weatherapi.com/v1/current.json?key=API_KEY&q=New%20York&aqi=no In this example, we are using the HTTP GET method to request weather information for New York. The request URL contains the API key and query parameters needed to complete the request. The response will be in JSON format.
Hi Raghav, Need some clarification here. In your example of Online Booking system where it uses the API services of other application and gives the output. My question is so how it sends the API request to multiple applications at once (simultaneously) and gets the response, displays to the user.
