 In sign, technical, disclaimer, speech, technical points are subject to disclaimer. So we are going to use a lot of technical terms and just to make sure that we are all on the same level. How many of us that wrote to our media, you've never heard about it. Let me ask. You've never heard about it and you don't know it and you don't even get partakes from the government. That's interesting. Okay, to me it's interesting but I'm sure that 99% of the world I've never... I know a lot. Thank you guys for your time. I've worked with you. I work as a support worker with media and you've done that. And I enjoy it very much. I always like to defend that. Me don't give me all that stuff. I was talking about writing out a thousand words. I think in a sentence, without thinking about the words. I have to spend the whole day thinking about the words. Just like it was difficult coming up with my own bio description for this work as well. Because I can't do that. But we can go ahead and talk about our EPIs. Something that at least I'm familiar with. So what's an EPIs for those of us who have never heard of them? He says he has never heard of them. He says he has heard the word but she's not so sure of what they are. I think there are only three people. Most of us know. Most of us know what an EPI is now. You know what an EPI is? You know what an EPI is? Okay, let me just ask him. He knows what an EPI is. He knows what an EPI is. Don't look at me like that. I think in a day or a month, we have to separate all the things out in a single boat. Okay, interesting. Let me get someone else. What an EPI is? Okay. You understand that this decommission that you're typing that you made is actually packaged in the weather. server, the server is somewhere, and I understand it, and so when you're typing this domain, you're actually making a request. In my government, what's wrong with those people? The thing is not the eating, but we know the next server is well-so. This is one of the main requests that we make, so last time you would find that you're interacting with any of these four requests that you can do on the internet. I can also have one which is there there, so like the first time I explain, every time you type in a domain, this domain actually carries certain information about whatever you're trying to do. It carries information like that time, the time that you're making this request, the size of the information that you're requesting for or that you are sending out, and all this information is kind of stored in like a header bit of your request. So if you want to be able to request, you can actually request for this information that you teach on, but you find that this one is mostly a result of the technical size, so then interact with a request, specifically request for information. But in total of that, we also have codes. The other responses that we receive, and I'm sure many of us have come across this, even those who don't know APIs or what, but if you go to the internet, you come across response codes. I just thought it would be nice to talk about them and educate us a little about what they mean. Maybe you come across them and you're not sure what they mean, but they are very good at what troubleshoot and find out what's actually wrong with whatsoever website or platform that you're using with. So understanding this response is very, very important. For example, you're working with APIs because it helps us to debug, it helps us to troubleshoot and know what to need to fix. So these are the main code classes that our response sends back. So the first one is the 200. Most of the codes, they call within one of these coding responses, one of these classes. So it will not appear as 2XX between 200 and 8, but it's within that range. So generally, the 200 codes mean that your response was successful. Anytime you come across anything on your browser, it shows you to make it 200. You just know your response was sent successfully, 20 successfully. Response 3, the 300, it means that your response was probably redirected to another browser. This probably will happen in the instance like, let me say, a cycle is moved from one link to another, making a redirect. So they are changing it from this here. They try to access something, but they redirected it somewhere else.
