0:00 We've gathered all the information about the order from the user. We've at each step along
0:05 the way verified what they entered was something that was actually valid.
0:09 We made sure that if they asked for a frosting that it actually was a frosting
0:13 available on our menu. So now it's time.
0:16 Once we got all that information to determine the price of the cake because ultimately they
0:20 want to purchase it and we're going to charge the money.
0:23 We need to at least tell them how much it's gonna cost.
0:25 Right? Recall We had our menu,
0:29 API appear that gave us the flavors,
0:31 the toppings and the frosting. We have a similar one for given this selection to
0:37 generate the price. Over here, we've got cloudcitycakecompany.azurewebsites.net/api
0:44 But now it's price calculator and we pass a bunch of
0:49 things along on the query string.
0:50 So size, flavor, topinng and frosting And these API's are
0:56 maintained by our British Software Development Team.
0:59 So we have our make sure we use our proper spelling over there.
1:03 So what I'm gonna do is I'm gonna copy.
1:04 Not the whole URL,
1:05 but this first part up to the query string,
1:09 but not including it. And we're going to use that over in studio to take
1:13 what they've given us and determine a price.
1:15 And ask them your cake is going to cost in this case,
1:18 eight gold coins. Do you want to buy it?
1:20 Yes or no? Alright. So back over here in studio instead of this test
1:24 where we said onward, we're going to actually do some other stuff.
1:28 So we'll go over here, and what we want to do is make another http
1:32 request, and I'm going to call it PriceCake.
1:36 And it's the right thing. We're gonna go over and call our API.
1:39 So then our URL is here.
1:42 Do a get with Form URL encoded data.
1:46 and notice down here we have an Http parameters.
1:48 This is the size of flavor and so on.
1:51 So instead of trying to come,
1:53 you know, build up a complicated URL
1:55 we're just going to do it over here,
1:57 so we'll have size, and then we need to use liquid to get the size
2:01 So cake. Uh, see,
2:04 this person came from the welcome.inbound.Message.body.
2:09 Remember, this is the thing we started of with.
2:11 I didn't mean to close it for you.
2:13 Make it larger. So this will be widgets.
2:15 Welcome, inbound body. This is welcome to the cake company.
2:19 What size of cake do you want?
2:21 The next thing that we need was we had the flavour and remember spell like that
2:26 So this was askcakeflavor.inbound.body
2:34 like so? So ask cake flavor,
2:39 widgets.AskCakeFlavor.inbound.Body
2:41 That's good. You have to add another will be our frosting.
2:47 Very similar. You can imagine Frosting.inbound!
2:55 Pick that one. widgets.AskCakeFrosting.inbound.Body
2:58 And last but not least,
3:01 are topping.inbound.Body like this,
3:10 which wigets.AskCakeTopping.inbound.Body save.
3:14 Oops! Save that one multiple saves on this piecer.
3:16 let's go back and actually send one more message.
3:25 Your cake will cost PriceCake.parsed
3:32 Okay. And we're gonna have our currently gold coins.
3:40 Save that. Connect them up.
3:42 Alright, Once we publish it,
3:44 we're ready to test. So can we call that PI with the right URL
3:48 and get the right response back.
3:51 We do. They're on to the next step.
3:54 Hi. Welcome, Welcome. Let's get a small cake.
3:58 Rainbow, Rainbow will be good, I think Vanilla on the toppings,
4:05 The frosting in the topping Let's go for Sprinkles.
4:11 Almost perfect. I guess if you're a program or maybe that's perfect.
4:15 So we got the total back end, I need to pull total out of the parse
4:18 value. So we'll do a .total on this,
4:21 But you can see that we successfully took all that information Small rainbow,
4:25 vanilla Sprinkle cake. And we sent that of to the pricing calculator and we did
4:29 get 22 back. It's got to work on our formatting.
4:32 So down here, we'll just say .total, we publish and order another cake.
4:45 Rainbow. Oh, I want a small rainbow,
4:56 some vanilla with Sprinkles. Check that out.
5:03 Your cake will cost 22 gold coins.
5:06 Come on over and pick up your cake.
5:08 Well, we're not quite that far yet,
5:09 are we? But we're getting there.
5:10 We're now figure out how much the thing cost.
5:13 We can ask them like this how much it's gonna cost.
5:15 Would you like to order your cake.
5:17 Now please say yes or no and then we'll go through,
5:20 get their information. What's their name?
5:22 What's their email and so on?
5:24 And we'll start their cake baking in the bakery.
