WEBVTT 00:00.120 --> 00:02.960 Oh, that was just a cheap move to get you to come to the next video. 00:03.000 --> 00:04.120 We're not going to do building. 00:04.120 --> 00:05.880 We've got one more slide to go. 00:06.400 --> 00:12.120 I just want to say one more thing, which is if you look back at this diagram that is showing you this 00:12.120 --> 00:20.480 idea of an endpoint request response HTTP to an endpoint, and then receiving an HTTP request to a webhook 00:20.520 --> 00:22.000 to notify us of something. 00:22.320 --> 00:27.000 There are nodes in that apply for each of those we've already discovered them. 00:27.000 --> 00:33.280 Like with slack showing here, we had a trigger that took a webhook and we had a, uh, like a, like 00:33.320 --> 00:37.320 a posting a message which which was a typical request response. 00:37.560 --> 00:44.200 And in many cases in HN, you'll find the sort of pair of nodes, one that takes a webhook and is for 00:44.200 --> 00:48.720 incoming events, and one that is about making a API calls. 00:49.120 --> 00:56.480 There are also generic nodes that are used to talk to platforms which haven't been explicitly built 00:56.480 --> 00:57.720 in N810 there hasn't. 00:57.760 --> 01:03.840 There isn't an integration component directly for that third party, but it has end points, so it has 01:03.880 --> 01:05.400 webhooks that it expects. 01:05.400 --> 01:10.440 And so you can sort of generically integrate with it based only on those URLs. 01:10.640 --> 01:18.560 And so there is a generic version of a request response node called the HTTP request node. 01:18.800 --> 01:22.200 And so it just calls a URL endpoint. 01:22.200 --> 01:23.520 You give it a URL. 01:24.040 --> 01:28.600 The node output is based on the results whatever comes back from that call. 01:29.240 --> 01:35.000 And then there is also a generic version on the other side there's a generic type of webhook and it 01:35.000 --> 01:36.800 is called the webhook node. 01:37.080 --> 01:42.800 And it has both a test URL and a production URL, just like the slack one did. 01:42.800 --> 01:48.720 It has a URL that can be called as a webhook for in test mode, or when you've actually deployed and 01:48.760 --> 01:57.200 you've activated that workflow, and it's triggered when someone else hits that URL, and you can configure 01:57.200 --> 02:03.490 it either to then respond immediately to the third party, or it can carry out a whole workflow and 02:03.490 --> 02:09.890 you can configure it so that it responds with whatever a later step returns comes up with. 02:09.890 --> 02:12.290 And those are some different configuration details we'll look at. 02:12.530 --> 02:20.170 But basically my point is that with some some external systems like slack, you get out of the box nodes 02:20.210 --> 02:25.130 like two nodes, one one for triggers and one for actually making making calls to it. 02:25.490 --> 02:30.890 And if you don't have an out of the box node like this, you can kind of make your own using these two 02:30.890 --> 02:35.130 generic nodes the HTTP request node and the webhook node. 02:35.650 --> 02:37.610 So hopefully that made sense. 02:37.610 --> 02:40.530 It's again something that will repeat a few times, so you'll get used to it. 02:40.530 --> 02:46.130 But that is how you build your own integration with a platform that isn't already sort of coming out 02:46.170 --> 02:47.530 of the box with any turn. 02:47.570 --> 02:50.410 Okay, it's time to be building stuff. 02:50.450 --> 02:51.650 I've teased you with this. 02:51.650 --> 02:55.130 Now we're gonna do it, and we're gonna start in 11 labs. 02:55.130 --> 02:56.770 You remember looking at 11 labs here? 02:56.770 --> 02:57.850 I've just signed in. 02:57.890 --> 02:58.970 You should as well. 02:58.970 --> 03:00.210 You've got this drop down here. 03:00.210 --> 03:01.090 Agents platform. 03:01.210 --> 03:02.490 Creative platform. 03:02.730 --> 03:06.050 Well, remember we're going to begin with technique one. 03:06.090 --> 03:07.850 N810 is going to be the boss. 03:07.850 --> 03:13.170 So we're not going to be setting up agents in 11 labs, but rather we're going to want to just use 11 03:13.170 --> 03:18.250 labs as a back end that can convert speech to text and back again. 03:18.650 --> 03:21.490 And the way we do that is using its API. 03:21.730 --> 03:24.130 And to do that, you need an API key. 03:24.650 --> 03:26.250 And this is how you get it. 03:26.250 --> 03:31.010 You go to developers which is down here, and you click on developers. 03:31.210 --> 03:35.490 And here we have a the section for developers. 03:35.690 --> 03:38.450 And there is a tab here API keys. 03:38.450 --> 03:45.610 And you go there and up it comes with some API keys like my one here Ed Key you are going to press Create 03:45.650 --> 03:46.050 key. 03:46.090 --> 03:49.130 I know you know how to make API keys, but I'm still going to show you it. 03:49.370 --> 03:52.290 It gives it a name and you're going to give it whatever name you want. 03:52.330 --> 03:54.010 Like I can call this key two. 03:54.410 --> 03:57.730 Uh, and it's good to have restrict key turned on. 03:58.130 --> 04:00.450 Now first thing it has here is monthly. 04:00.610 --> 04:03.690 And this looks like a monthly limit, which is a good thing to have. 04:03.690 --> 04:09.250 And you might think, like I originally did that typing ten in there would mean $10 a month, but it 04:09.250 --> 04:09.730 doesn't. 04:09.730 --> 04:15.530 It's talking about the number of credits and most calls we make take take 3060 credits or something 04:15.530 --> 04:15.970 like that. 04:15.970 --> 04:19.010 And you should have lots of free credits that came with your plan. 04:19.010 --> 04:24.690 And if you're on a pay plan like me, I've got tens of thousands of free credits baked in, so you should 04:24.690 --> 04:30.450 put whatever monthly number you want here, but I recommend a number like 500 is a good a good number 04:30.450 --> 04:31.530 for what we might want to do. 04:31.530 --> 04:32.490 And keep an eye on this. 04:32.490 --> 04:38.490 And you might need to come up and dial it up if you've if you've used up your monthly credit limit and 04:38.490 --> 04:41.490 then you want to be able to basically have access to all these things. 04:41.490 --> 04:45.370 So select access to this, access to this access access access. 04:45.770 --> 04:48.210 And then we don't need write access. 04:48.210 --> 04:50.890 I think read should be fine for all of these things here. 04:51.330 --> 04:57.130 And then uh, I don't think we're going to use these but access for everything anyway and then read 04:57.130 --> 04:58.890 for all of these things. 04:58.930 --> 05:02.130 And when you've done that, you press the create key button. 05:02.130 --> 05:03.410 It pops up with a key. 05:03.450 --> 05:06.410 You copy it into your clipboard and you say, okay. 05:06.450 --> 05:11.170 And you keep that there in your clipboard because we're going to need to paste it somewhere else, and 05:11.170 --> 05:13.650 maybe you keep a record of it safe and sound. 05:13.650 --> 05:17.530 And if you ever have a problem with your API key, you know what to do. 05:17.570 --> 05:23.610 You come back here and you create another one, and you can always come here, and you can disable a 05:23.610 --> 05:25.490 key if you're no longer using it. 05:25.530 --> 05:29.250 And you can also come in and edit it if you want to give it different permissions. 05:29.410 --> 05:31.410 So this is the thing to do. 05:31.930 --> 05:34.490 Always be careful with your API keys. 05:34.530 --> 05:36.490 Copy it carefully. 05:36.530 --> 05:38.090 Don't paste it into a word processor. 05:38.090 --> 05:38.810 You know the deal. 05:38.850 --> 05:40.530 Uh, and you can always create a second one. 05:40.530 --> 05:41.090 Okay. 05:41.130 --> 05:46.010 So here we are back into innate and I'm going to sign in. 05:46.170 --> 05:51.490 This is signing into our cloud accounts and into our instance. 05:51.490 --> 05:52.450 And here we are. 05:52.730 --> 05:57.810 And I'm going to press the Create Workflow button here to start our new workflow. 05:58.250 --> 06:05.340 And let's begin this time with with the with a chat the on chat message to get us started in the usual 06:05.340 --> 06:05.500 way. 06:05.540 --> 06:07.660 Click and escape to come back here. 06:07.660 --> 06:12.500 If you're seeing logs up here like this, remember you can just click there to get rid of them okay. 06:12.540 --> 06:19.940 And then let's click plus or press tab and then go to the AI agent selection. 06:19.940 --> 06:20.700 Here it is. 06:20.820 --> 06:23.540 Escape back we come the chat model. 06:23.540 --> 06:27.700 So so you can use as always open router or open AI. 06:28.300 --> 06:34.500 This time just just for this week to keep it different I'm going to look to use Google Gemini. 06:34.540 --> 06:37.780 Google Gemini is going to be our one for today. 06:38.060 --> 06:44.660 Uh, and for Google there's two different there's Google Gemini which is referring to the AI studio, 06:44.940 --> 06:46.060 uh, Google's AI studio. 06:46.100 --> 06:51.180 There's also vertex AI, which is a bigger deal, and which if you know it, you know it. 06:51.380 --> 06:53.780 Otherwise, stick with this one. 06:54.020 --> 06:58.420 And for the credential I'm going to go create new credential. 06:58.580 --> 07:00.780 And I have set up an API key. 07:00.780 --> 07:07.060 And I have set this up at AI studio google.com, which is where you set up the Or you just search AI 07:07.100 --> 07:08.780 studio, Gemini AI studio. 07:08.980 --> 07:15.980 And I have set up an API key and I've been careful and I paste it in here and I press save and I see 07:15.980 --> 07:21.820 the connection was tested successfully, as will you, because you are a pro with API keys and they 07:21.820 --> 07:22.900 never give you any trouble. 07:23.420 --> 07:24.100 All right. 07:24.100 --> 07:27.060 So with that we're going to be experimenting with Gemini. 07:27.300 --> 07:30.860 And uh, let's uh, let's just just finish this off. 07:30.860 --> 07:35.780 So we're not going to give it any, uh, tools or any memory for this, this one. 07:35.900 --> 07:37.060 Um, let me just see what I see. 07:37.060 --> 07:38.940 We've got Gemini 2.5 flash. 07:38.940 --> 07:41.340 Let's see if we can't give it Gemini three. 07:42.580 --> 07:43.300 Hang on. 07:43.780 --> 07:45.700 Um, models. 07:45.940 --> 07:48.540 Gemini three. 07:49.580 --> 07:50.540 Uh, there we go. 07:50.580 --> 07:51.460 They've got Gemini three. 07:51.460 --> 07:52.460 Flash preview. 07:52.500 --> 07:56.100 I imagine by the time you see this, it'll just be Gemini three flash. 07:56.100 --> 07:57.700 But you should pick the one you want. 07:57.900 --> 07:58.980 That's what I'll pick. 07:59.260 --> 08:05.380 And with that, let's come here, open the chat and say hi there. 08:07.860 --> 08:08.820 And off it goes. 08:08.820 --> 08:09.140 Hello. 08:09.140 --> 08:10.140 How can I help you today? 08:10.140 --> 08:10.460 Great. 08:10.460 --> 08:12.420 We have Gemini working. 08:12.540 --> 08:14.540 Not much to do with voice just yet. 08:14.820 --> 08:20.060 Okay, well, the next thing we're gonna do is add on something here, which is going to make an API 08:20.060 --> 08:26.500 call to 11 labs to turn this text into audio. 08:26.500 --> 08:28.300 So I'm going to press the plus there. 08:28.300 --> 08:31.260 And I'm going to look for 11 labs and up. 08:31.260 --> 08:33.740 It comes as a possible next node. 08:33.780 --> 08:35.380 Now when you click on this it will come up here. 08:35.380 --> 08:39.460 And I imagine for you you will see it as like not installed. 08:39.460 --> 08:41.940 And there'll be a button here to install it. 08:42.220 --> 08:45.460 And that is something you want to press that button to install it. 08:45.500 --> 08:49.700 If you're I assume you're using cloud, in which case it's just a matter of pressing that button and 08:49.700 --> 08:50.660 it gets installed. 08:50.660 --> 08:56.220 If you are actually using the self-hosted version, uh, then you have to go through a couple more steps, 08:56.220 --> 08:58.340 which you can just Google to find out about it. 08:58.340 --> 08:59.140 Super simple. 08:59.140 --> 09:05.180 It's like a community node that you just install, but it's very quick and then it will be installed 09:05.180 --> 09:06.140 like this. 09:06.140 --> 09:11.220 And now we can come down here to the possible actions, the node actions. 09:11.220 --> 09:14.140 And we want convert text to speech. 09:14.260 --> 09:15.300 That's what we want. 09:15.340 --> 09:20.420 And up comes this node for us to connect to 11 labs okay. 09:20.460 --> 09:25.620 And the first thing we got to do is select a credential, create a new credential. 09:25.620 --> 09:28.100 And it needs the 11 labs API key. 09:28.140 --> 09:30.300 The thing we created over in 11 labs. 09:30.460 --> 09:34.100 And I'm now gonna paste in that key that's in my clipboard. 09:34.140 --> 09:37.620 Obviously if you just copied one from Gemini then that won't work. 09:37.620 --> 09:39.780 It's got to be 11 labs API key. 09:40.140 --> 09:41.420 And I save that. 09:41.420 --> 09:47.500 And I'm a pro at this and that's why it says connected and tested successfully first time. 09:47.500 --> 09:49.780 And you got that too because you're a pro as well. 09:49.820 --> 09:50.540 Congrats. 09:50.900 --> 09:51.500 All right. 09:51.980 --> 09:54.780 If you didn't you're like uh but hopefully you did. 09:54.820 --> 09:55.380 All right. 09:55.380 --> 09:58.260 So now we choose the operation text to speech. 09:58.540 --> 10:00.620 We choose the voice from the list. 10:00.660 --> 10:01.900 Let's choose Ms.. 10:01.940 --> 10:04.980 Walker Because she's warm and reassuring. 10:04.980 --> 10:06.260 And that's what we like. 10:06.500 --> 10:10.580 And now we have to choose the text to say this. 10:10.580 --> 10:15.940 This is where this this is the input that will be sent to 11 labs to turn into text. 10:16.020 --> 10:20.380 And you know, if we put the word bananas in there, then it would always generate audio for bananas. 10:20.380 --> 10:21.500 And that's not what we want. 10:21.540 --> 10:23.060 We want it to be different every time. 10:23.060 --> 10:25.060 And so we're talking about an expression. 10:25.340 --> 10:29.220 And you may be wondering why can't we say let the model decide. 10:29.260 --> 10:31.500 Remember you can only do that with tools. 10:31.500 --> 10:33.460 It's only if it were a tool that you could do that. 10:33.460 --> 10:34.620 And this isn't a tool. 10:34.620 --> 10:39.060 This is just the next step in the workflow, because we don't want the LLM to decide whether or not 10:39.060 --> 10:40.060 to generate audio. 10:40.100 --> 10:42.180 We always want to generate audio. 10:42.180 --> 10:44.940 So there's no there's no LLM decision here. 10:44.940 --> 10:46.420 It's a step in the workflow. 10:46.740 --> 10:52.900 So how do we how do we put the text here to say use whatever was the output from the LLM. 10:53.220 --> 10:55.860 Well of course we don't want something fixed. 10:55.860 --> 10:57.380 We want an expression. 10:57.580 --> 10:59.980 And you're a pro with expressions as well now. 10:59.980 --> 11:03.470 So hopefully I'll give you a moment to think what the expression is. 11:03.750 --> 11:07.070 First of all, there's curly braces around it and two of them like that. 11:07.350 --> 11:14.190 And then the way that you say, I want the, the, the, uh, the item from what came into me in the 11:14.190 --> 11:16.870 form of JSON, you do dollar, JSON. 11:17.230 --> 11:22.310 And what I want from that is the field you can see on the left there that's called output. 11:22.310 --> 11:25.790 So you do dot output and look at that. 11:25.830 --> 11:28.710 What you see in result is hello how can I help you today. 11:28.870 --> 11:29.790 Perfect. 11:29.790 --> 11:31.110 And of course the other way you can do it. 11:31.110 --> 11:32.470 You don't need to type it out like that. 11:32.470 --> 11:36.310 You can also just simply drag and drop over there like so. 11:36.830 --> 11:38.910 And if you have to, you have to drop properly. 11:38.950 --> 11:39.670 Try that again. 11:39.710 --> 11:40.550 There we go. 11:40.590 --> 11:42.150 And you get the same thing. 11:42.310 --> 11:43.590 You don't need to type the code. 11:43.590 --> 11:44.990 You can always just drag and drop. 11:44.990 --> 11:52.510 And so this will configure us so that whatever's coming in uh to this node, it looks into it, it looks 11:52.510 --> 11:53.590 at the output field. 11:53.590 --> 11:59.830 It takes that text and it sends that text to 11 labs for text to speech for Ms.. 11:59.870 --> 12:03.830 Walker using our 11 labs API key.
