• Buttons- we provide options to create three buttons so that the user can choose from them. 
  Like: Content- Do you want to know about our products, NO and MAYBE. You can add a maximum of 3 buttons.

    Note: Slot names should not be the same for multiple slots, it is a required category.

    
    

    Like if you want to know the size of the product, and the type of the product from the users.

You can add as many questions here as you want to ask from the users.

Here you have to provide the following:

13. In the Blank Option: You can add information as per your requirement.

There are two options: If you select the first option which is "Blank", then you will see there are two value type options first one is: 'Dynamic' and the second one is 'Fixed'.
In Dynamic- The Bot will accept similar or the same values as you will provide in the sample. 
In the Fixed option- It will accept only the value you have mentioned in the sample, the exact value.
​

14. For Dynamic Value Type:- We are providing some in-built slots but if a user wants to create any custom slot then they can use the dynamic type. 

    1. You need to add on 10-15 same types of sample values trained by a bot
       For Example, we consider NAME as a slot type
       1st character - u, 2 characters - Om, 3 characters - Joy, 4 characters - Anuj, 5 characters - Raman, 6 character - Rakesh 

                                

In Fixed: The Value you set the same will show. 

If you want to take specific 3 to 4 country responses you can give specific names in fixed 

For example - If your question is from which country you are? 

India, USA, Australia - 

If the answer is related to these 3 countries then the bot responds, other than the bot will not reply.

If you add on the sample values and synonyms for the fixed type, then by default it will pick the sample values at the first attempt and then it will take on the synonyms. 

                      

Click User input type Built-in: Basically, it is the extended functionality we are providing by using the Built-in Input Type. In this functionality, you can verify the input provided by the user of your slot prompt.

For now, only the Alpha Numeric input type is supported.

Use case: For example: 
If you want the user to provide the Postal Code, the business is supporting mainly 3 formats which are: Numeric for India {123456}, Alpha-numeric for UK {GU16 7HF}, and Numeric-numeric for US {1234-12345}. In that case, the business will create the Regex Expression which will support all three postal codes.

Once you add this, the input type will start showing in the drop-down of input type, from there you can select this input type.
