then we gather the new size and color

now that we know what we are building

Now that we know what we are building,

let's head to dialogflow cx console the

let's head to Dialogflow CX console.

easiest way is to get there from the

The easiest way is to get there from the documentation.

documentation create a new project make sure you

Create a new project, make sure you enable <i>Billing</i>,

enable billing and the dialogflow api

and the Dialogflow API.

then we go back into the dialogflow cx

Then we go back into the Dialogflow CX console

console and click on the project we just

and click on the project we just created.

created it prompts us to create an agent that's

It prompts us to create an agent.

exactly what we want to do

That's exactly what we want to do.

we name it select the location where we

We name it, select the location where we want to deploy it,

want it it and the time zone and the language

and the timezone, and the language,

and we're good to create now notice that

and we're good to create.

within a project we can create

Now, notice that within a project,

multiple agents we have our default

we can create multiple agents.

We have our <i>Default Start Flow</i> with our <i>Start</i> page,

with our start page which comes with the default welcome intent

which comes with the <i>Default Welcome Intent.</i>

so let's go ahead and test it at this

So let's go ahead and test it.

point all it does is greets the user we want

At this point, all it does is greet the user.

to create a transition route

We want to create a <i>Transition Route</i> from the <i>Start</i> page

from the start page that leads to the

that leads to the <i>Order</i> flow.

Create new <i>Intent</i>.

create new intent let's name it and add

Let's name it and add some training phrases.

some training phrases let's add some basic ones such as i

Let's add some basic ones such as,

would like to place an order

"I would like to place an order."

but we also need to add some specific phrases with color

But we also need to add some specific phrases with <i>color</i>.

let's add i want to buy green shoes for

Let's add "I want to buy green shoes for my pup."

my pub as soon as we add that that notice that

As soon as we add that, notice that the color parameter

the color parameter automatically gets created with sis dot color entity type

automatically gets created with <i>@sys.color</i> Entity type.

and this color parameter will be stored

And this color parameter will be stored in the session for us

in the session for us to access in other

to access in other pages.

pages also since the user has already provided

Also, since the user has already provided the color,

the color our agent will not ask for that

our agent will not ask for that information,

information providing a more natural experience

providing a more natural experience.

now let's add another example with the

Now, let's add another example with the size.

size i want to get large shoes for my husky

"Wanna get large shoes for my husky."

now we see that the large is not

Now, we see that the <i>large</i>

automatically identified as a parameter

is not automatically identified as a parameter

because size is unique to pugs use case

because size is unique to PUggs use case.

so let's fix that but before we do that

So let's fix that.

add a transition to new page

But before we do that, add a <i>Transition</i> to <i>new Page</i>

where we will collect information and

where we will collect information and save it.

save it let's go into manage entity types and then create

Let's go into <i>Manage > Entity Types</i>, and then <i>Create New</i>.

new name it size and add small medium large size in there with some

Name it "size," and add <i>small, medium</i>, <i>large</i> size in there

with some synonyms.

now while we are on the manage tab let's

Now, while we are on the <i>Manage</i> tab,

go into the intent to see if we can add

let's go into the <i>Intents</i>

our size parameter now

to see if we can add our "size" parameter now.

add one or two more examples with both

Add one or two more examples with both <i>size</i> and <i>color</i>

sides and color to add some variety

to add some variety.

let's head over to our collect

Let's head over to our<i> Collect Information</i> page

information page and add the entry

and add the <i>Entry dialogue</i>

to let the user know

to let the user know that we will collect some more information now

that we will create some more information now.

then add the parameter size is a

Then add the <i>Parameter</i>.

required parameter and if a user does

<i>Size</i> is a required parameter,

and if the user does not provide it,

we want to prompt them with the

we want to prompt them with the <i>Fulfillment</i> here.

fulfillment here we repeat the same for color as well

We repeat the same for <i>color</i> as well.

With that, we are ready to define

we are ready to define our transition routes from this page

our <i>Transition routes</i> from this page.

and in this case we don't need to

And in this case, we don't need to trigger an <i>Intent</i>.

trigger an intent all we need is to make sure our parameters are

All we need is to make sure our <i>Parameters</i> are filled in.

filled in so we look for the condition to match page.paramster status

So we look for the condition to match:<i> $page.params.status = FINAL</i>

equals final once all the parameters are defined

Once all the <i>Parameters</i> are defined and collected,

and collected which means both size and color in this case that's when the

which means both <i>size</i> and <i>color</i>, in this case,

status will turn to final

that's when the <i>status</i> will turn to <i>FINAL</i>.

this is also where we can match other

This is also where we can match other conditions,

conditions such as if the parameter parameter.colors equals

such as if the <i>$page.params.color = RED</i>,

red then send to a sorry page because that

then send to a "sorry" page

color is not available in the inventory

because that color is not available in the inventory.

once the status equals final condition

Once the <i>status</i> equals <i>FINAL</i>, condition is met.

is met we would route the user to the new confirmation page

We would route the user to the new <i>confirmation</i> page.

In the <i>confirmation</i> page,

the entry dialog to share

let's first add the <i>Entry dialogue</i>

what they have selected to buy we can

to share what they have selected to buy.

access the parameters in the session by using the dollar sign

We can access the <i>Parameters</i> in the session by using the <i>$</i> sign.

we don't have any parameter to add for this page for

We don't have any <i>Parameter</i> to add for this page.

For the <i>Transition routes</i>,

routes we want to have a yes and a no

we want to have a "yes" and a "no" route.

route for yes path let's create a new intent

For "yes" path, let's create a new <i>Intent</i>

and call it confirmation.yes and provide

and call it "confirmation.yes,"

a few training phrases that indicate

and provide a few <i>Training phrases</i> that indicate "yes."

yes save the intent and then add the transition page

<i>Save</i> the <i>Intent</i> and then add the <i>Transition</i> page as "Success."

<i>Success</i> page is easy at this point.

we need to do is add a nice entry dialog for the

All we need to do is add a nice <i>Entry dialogue</i>.

transition route add true in the

For the <i>Transition route</i>, add "true" in the <i>Condition</i>

That doesn't quite work.

because the parameters are already

And that's because the <i>Parameters</i> are already filled.

filled we need to clear up the

We need to clear out the <i>Parameters</i>

parameters before the state changes to the start page and we do that

before the state changes to the <i>Start</i> page.
