What is a REST API? 

Is no one else going to say it? This video is in Dark Mode, and that's why we love it

I'm not sure if I'm more impressed with the explanation or the fact that he wrote all this stuff backwards to our viewpoint

The mirror, fluorescent markers, the lightning, black background, this video looks amazing!

One of the best representations and explanations of this architectural pattern. REST really is straight forward if you can simply think about how the data should come and go in your app!

I was marveling at how he was writing backwards so easily, but the I realized that it's just mirrored. Dude's right handed

I worked as a Business Analyst on an Open Banking project - Gosh I wish this video/resource was available to me to simplify the crazy first couple of months to digest this information. Enjoyed this, very well done and simplified. Great job!

This was by far one of the the simplest and at the same time, thorough enough explanations about REST Apis. Big Thanks

This really helped clear up for me what a REST API is and how HTTP methods work. Marker squeak was a little painful but I appreciate the content.

As a person who is just starting out learning about APIs and Integration...this was a goldmine. Thanks a lot!

I can't help but think of the fact that he's technically writing backwards

Hey, Nathan Hekman , You are a wonderful presenter and you example was so précised, clear and from real world. Please keep making more content. It was a great video with great content.

Never seen such enthusiasm while explaining stuff :) GREAT!

Amazing video man. Understood it quickly and clearly. Loved the editing etc and the breakdown of timeline. Great work!

I'm a former techie who left the industry for a while, and came back as a leader of a large group of techies, so I'm playing a little bit of catch-up with videos like these, so I know what my teams are doing and can provide guidance or prioritisation. This video was straightforward and helpful. Thank you SO much for the really excellent, approachable and deliciou---I mean, descriptive bite of ice c---I mean, information. Damnit, I'm going for the Ben & Jerry's.

i made my first web app with REST weeks ago without knowing 100% of the concept. I wish i saw this video before! All i knew is that i needed to change my dependencies, make my link, make the client-server architecture and communicate with my DB with SQL commands. Great stuff!

i have watched many videos regarding rest API, but no one explained it this much clearly.. great job 🔥

It's rare to find good quality tutorial videos. And I am saying this cause I didn't know how time flew by when you were teaching. And it didn't happen just once, multiple videos. Grateful 🙌🙌🙌

Really great production. At first, the dramatic lighting was jarring, but later when the board filled up, the shadows helped separate the talent from the text we were looking at it. Bravo to the presenter, too

This is THE video I've been needing thank you. All other videos just start diving into way basic different stuff or just go with examples of APIs. Thanks for this!

This was so smooth that I was already familiar with REST APIs but ended up watching the entire video, great work IBM team :)

Probably the best explanation of REST API...very easy to understand. Thank you!

I was freaking out about how well this guy was writing in reverse until I realized they probably just flipped the video.

Probs the most straight-forward and simple intro to REST APIs. Thanks for this!

REST (Representational State Transfer) API - commincating with the server (Cloud commincation) - works with restfull service - Simple/Standardized - Scalable/Stateless - High perfmorance/cacheing - Request: CRUD (Create(Post) Read(Get) Update(Put) Delete(Delete)) - Request may include Header, endpt, paramter/body - Response get the data in either JSON or XML format

LOVE LOVE LOVE your teaching style. The video and audio quality are great. If you used EQ in post production to get rid of high pitched marker squeaking sounds that would really improve my experience and hopefully others who are sensitive to high pitched sounds. Thank you for your teaching!

Thank you! Insanely helpful and informative, simplified on a topic that is hard to simplify.

Been struggling to understand RESTful API, this video helped understand it in much simpler, broken down terms. Thank you so much!

I really like how simple and useful this is! Your explanations made RESTful API so easy to understand.

For the first time in my life, I know what a REST API is! Thank you

The content is really amazing, never found an explanation something that detailed and simple.

The whiteboard presentation was amazing! Know the concept of API easily!

one of the best explanations i have seen about REST API . this is by far the best and clear elaboration of this topic. good job !!!

Thank you for this simple explanation. I'm by no means a real programmer but my work wants me to build a simple app that uses this stuff. This is extremely helpful.

This was a great, simple and short explanation, thanks!

The dark mode vibe is amazing! Posted this from the CLI

BEST 10 minutes class ever! Thank you so much!

Outstanding and informative examples. You're going to go far in this field.

Nice video! Heading to bed now for a RESTful sleep.

These IBM vids are really well done and the info is on point! Thank You!

omg I haven't seen a beautiful mesmerizing explanation of REST API

The way you explained this was so amazing and simple to understand,thank you ! kudos to your understanding and teaching 👏❤

Manager: *Why isn't your APIs responding?* Me: *Its RESTing*

Just started learning about API's and servers this week. This video is great for visual learners like me (in fact the best one i've seen)

Truly one of the best videos i found on the internet for a beginner!

awesome explanation! at first, I thought you were writing left handed and backwards, but it makes more sense that you were writing right handed and forwards, and then flipped the vid in post-production. I love this format! Keep it up!

Best video on youtube on this topic by far. Thanks a lot!

this is easily the BEST explanation I have ever come across. thank you!

My Brain just exploded with the best explaination that i've seen about REST/RESTFUL architecture.

A great video. Very good explanations and examples of the key points. Thanks for posting.

Learned web development from Jonas udemy course. And now seeing this video keeps my learned concepts fresh and improved ☺️

The fact he able to write on the glass inverted so we can read it is just stunning!

Beautiful explanation even a non-technical person can understand. One feedback, the marker sound was making me crazy though

This is a pretty cool breakdown. Thanks!

Thank you so much, after consulting and reading many articles over the internet couple with some videos, yours finally explained everything, clarifying what REST and RESTful API is... Thank you so much, how wish I can subscribe more than once, would have done that. Thank you.

VERY well done. Explained well with no drama. Thank you!

Great Job! looking forward to see more videos like this. Is in the scope of this videos, the continuation of this icecream shop example? I would love to see how actually USE all this requests and responses in the website/app. With this methodology would it be great to see the front-end part. Now is time for an ice cream. Cheers

need more focused on authenitcation like security and how actually the request is been made,

I do have lots of questions. Honestly, the learning video enlightened me. Thank you. Super work.

The Best API tutorial on the planet, ....................... No the Universe. Now I can REST searching for tutorials on API.

Um, what is thie black magic vodoo he is doing with his whiteboarding?! I hear the marker but there is more to this. I love it.

Great and Simple, Just curious how its different from traditional web service,one could be stateless ,any thoughts...Keep up nice one.

Best API 101 I’ve seen…. Nicely done guys!

This is one of the best explanations I've found on the topic!!! And I've seen a lot :D This video is great! Thank you!

RIP headset users. squeak squeak

I gave this video a like just because of the "RESTful Flavour" joke.

You're a genius and the way you explained was so clear and understandable even for people who are in beginner-level

I didn't get how REST API is advantageous and how does it differ from API

This is RPC over HTTP at most. Any presentation that does not include the words MediaType or Hypermedia can not be about REST. I get that the industry in general basically rejected hypermedia, but it is still an integral part of many of the advantages claimed. Also, it is not simple at all, you're just doing the simple parts and ignoring the hard ones, like caching (mentioned, but then forgotten), discovery or resources, designing the flow of the client _from the server_, etc.. That added knowledge is what makes REST so powerful, not the making some random HTTP requests with some json content. The linked "Handbook" and "REST APIs" documents are also talking mostly about the RPC-style. With the only mention of links in "paging". Don't underestimate the power of links and forms! Come on IBM, you could actually lead here, and show how it's done properly! Leave the OpenAPI/Swagger train and do it right!

My first video on the rabbit trail. Thanks for the info

im incapable of learning code and stuff that i need for QA and i understood this so easily. Thank you

endpoint, method and parameters cannot always be differentiated. rest is only a solution for using a very small set of crud operations on databases. rest api just: 1. enables browsers to use http protocol to access databases 2. enables connection pooling at the application server and removes necessity to connect to a database for every function call 3. constrain the client to use only a couple of functions rather than enabling them to use full range of commands that can be used when directly connected to a database. i think a more generalized solution is required to solve wide range of operations. what i suggest is to use stored functions defined in database systems that use json as input and output. a thin and fast application server should do only connection pooling, firewall and logging functions. a server should be used to generate authentication keys and these keys should be checked by functions on the database server for authorization. with this simple design there will be almost nothing that cannot be achieved and there will never need to add extra servers to do things that cannot be done with this architecture.

A big thanks to the editor for muting while writing. It helps big time. Thats a painful sound.

Man this is very straight forward. Thanks mate.

Thank you. That was really helpful and answered several questions I had. Liked & Subscribed.

This guy's ability to write backwards ... or maybe the video simply flipped.

Omg your marker squeaking is horrific. I really wanted to watch this too.

I’m korean and not proficient at English but this video makes me understrand REST API. it is so awesome video :)

Genius presentation. I love the 2-way approach

U have mastered teaching and explained this in very simple terms and a lovely meaningful video, Thanks a ton.

Really liked how CRUD ops were related to the HTTP ops (GET, POST, etc)... thank you for sharing.

This is the best teaching video I have ever seen on this subject, thank you!

Great video and explanations. Simple to understand and the way he was writing on the screen/glass was crazy and easy to understand. Idk how they do it though lol

Although api exist for years, your video is excelkent. Simple and clear explanation! Great! Thsnks!

Perfect explanation! Finally understand API!

LOVE the squeaky marker. Makes me feel like i'm interacting in a real classroom

I finally understand POST and GET after the django tutorial I watched thanks!

Thank you for explaining this in such an easy way to understand.

I like the inverted glass thingy, preety creative.

Thanks! That was so clear and comprehensible

I've been trying to figure what I need to do for a Python web application I'm building for a CS class. This was very helpful!

This was extremely helpful. It also helped me understand JSON a little better.

The dark mode vibe is amazing!

Its very simple, helpful and informative. Thank you....!

Very helpful, simple, easy to understand. Thanks so much🙏

this is such a great explanation in a short amount of time

wow this is one of the best and simple to understand explanations thank you

Super awesome. Thank you for making easy for a non programmer to understand this at a technical and useful way.

Awesome!. You make it simple to understand. Love it, thank you

Thanks, this clarified a lot for a beginner

Wow! Best Explanation Ever with That Awesome Transparent Glass & Colorful Pencils.
