Custom Intent – By creating custom intent you are able to add it as a button on WPBot message board. You will able to see the button if you type start and hit enter on wpbot. So you can extent the functionality of WPBot by creating your own dialogflow intents.
- Intent Name should be identical to dialogflow intent name and the intent name must be added in dialogflow intent traning phrases.

- If you have created a Step by Step Question Answer Intent in DialogFlow, you can Enable the Option to have the Answers emailed to you. This can be used to create a Poll or Survey – If you click on the checkbox it will send the specific intent conversation to wpbot admin. So you can easily get feedback from user by creating a custom intent and click this box to get an email.

Creating follow-up intents for DialogFlow agent

First you have to create main intent that will match the user’s order request such as “I need a Caramel Macchiato.”.

Next, we’ll add a second intent nested inside the main intent, these nested intents are called “follow-up” intents. Follow-up intent are normal intents that hold the context of their parent intent. In order to add follow-up intents, simply hover your mouse over an intent and click on the “Add follow-up intent” label:

This will add a new intent nested inside the selected intent. We can choose from a wide variety of common follow-ups expressions such as confirmations, repeating, canceling…etc. Or, we can just add a custom follow-up intent:

Let’s get back to our conversation from above. We have two scenarios that we need to design:

If the user just asks for a coffee and then confirms the order, we just need two intents: the main intent + a “yes” follow-up intent.
If the user wants to add extra toppings, we then need three intents: the main intent + an “extra” follow-up + a “yes” follow-up (for the extra).

In the end, we’ll have something like the following:

user.order: our main “order” intent.
user.order — yes: a confirmation for the order.
user.order—extra: an intent for the extra toppings.
user.order—extra—yes: a confirmation for the order with toppings.

*For Sending Card Response

Let’s create an intent add some traning phrases for sending card response.
Now in Responses Tab click on the Plus(+) button beside the Default and select “Facebook Messenger”. This is because the rich messeging does not support in default response in dialogflow

After selecting Facebook Messenger please turn off the “Use response from the DEFAULT tab as the first response.”
Now click on the Add Response button and select Card.

After clicking on the card you can able to provide information about card. You can add card as many as you need by clicking on the Add Responses button. After providing all information it will look like the below screenshot. After you have done with card then save the intent.
