Introduction to webhooks

0:00 web hooks in nadn can be extraordinarily powerful but a lot of people misunderstand how they work so in this video I'm going to run you through everything you need to know about the nadn web hook game to crush it let's get into it so I'm going to get into the NAD and canvas in a second but just before I do I want to talk a little bit about what web hooks even are because I feel like in n8n and a lot of no and low code tools in general there's a big misunderstanding so to make things extraordinarily simple all web hooks are okay is they are messages they're nicely formatted messages but they're messages so if you have two apps let's just call this app a and over here we'll call this app B all the web Hook is is this just a message from maybe app a to app b or from App B to app a just a text you know a very specifically formatted text it's like if you are going to the grocery

0:47 store and you see your friend's ex-girlfriend or something and you're like hey I just saw Stacy at the store right that that is the web hook it's just we're formatting in a very particular way so to make this a little more practical since we're using a no and lo code tool presumably for the of business let me just cover a set examples but let me just do one so we can actually jump into building uh let's say this app a here is I don't know it's like an email client okay so this is your email client I don't know it's your Gmail your outlook or or whatever um and basically what happens is when I get a new email right what I'll do is I'll send a web hook this is a very common flow a lot of businesses do exactly this I'll send a web hook over to let's say appb as your C CRM you know when I get a new email what I want to do is I want to add some data to my CRM I do that using

1:36 a web hook so um this is your new email you go to your email client you configure some web hook then you send it over to your CRM and what you do is you add a new record maybe with like the email address which is encapsulated in the web hook data um I don't know the first name right last name all sorts of stuff I can tell my writing is kind of getting doctor scrawly so I'll stop there but essentially that's web books are they're just little packets of data that we send to and from apps now the reason why uh they've become so prevalent in the 2020s and Beyond is because we are we're kind of getting in the habit of integrating things right and the purpose of a no or low code tool kind of in its core is to glue a bunch of different platforms together so naturally web hooks are a core part of how you get really good with these things so you know whether you're using

2:21 make.com or zapier or Hell any no or loow code platform you're going to be you're going to have web hooks uh naden exposes web hook functionality to us in a couple of simple ways the first is we have the ability to catch a web hook that's what it is called when you receive one of these messages using the web hook node and we also have the ability this is sort of um Advanced I'm going to show you it right now anyway we also have the ability to send data from nadn to the source that sent us the web hook to begin with so basically respond to an incoming web hook now we're going to cover how this works in a moment um but essentially these two pieces of functionality nowadays are like a core part of how the internet operates and they're one of the reasons why inid in's great because they allow you to very quickly and easily slot into any app

3:09 whether or not it has like a built-in integration if we click on this little button and we search for actions yeah don't get me wrong there are quite a few actions here maybe a few hundred but there are many more apps than this out there on the internet and if you want to be able to integrate all of those apps together well you can't just go down this list because the vast majority of them don't exist what you need to do is you need to find some sort of custom way to do so web hooks are that custom way
