Slots
Slots describe the input and output fields associated with the intents, which are used for processing the intent. These might also include the inputs for the Web API requests, if any, associated with the intent. You can define the Slots by using the slot button under the Action column.

Templates
In natural language, users often provide multiple information in a single sentence, especially in commonly used phrases. Consider the following examples
Templates allow multiple slots to be captured together from User utterances. In the above examples, multiple slots can be captured from the slot from single sentences. To define a template, select the `Template` button under the _Action_.
Templates allow multiple slots to be captured together from User utterances. In the above examples, multiple slots can be captured from the slot from single sentences. In order to define a template, select the Template button under the Action.
Templates are defined by using the $slotName syntax for capturing slots. For example, assuming we have startDate and endDate as our slot names, a template in a leave management application might look like
The Templates can be instructed to support multilingual functionality if the bot was designed to the multilingual. You can enable the functionality by using the Auto-translate flag.
We can use the Templates to read multiple inputs together from user utterances. For example, for the startDate, we can define the template as "leaves from ${startDate} to ${endDate}". This would ensure the startDate and endDate are filled when the user utterance is similar to any of the following.
Prompts
In addition, you can also define Prompts for each of the slots if the User fails to provide the required inputs. These are the messages which the chatbot would ask the user when there is missing information. For example, for the startDate the prompt could be defined as
Dhee.AI also allows configuring slots using prompts that show predefined values. For example, We could prompt the user for specifying the reason for leave application using predefined custom values. For example,
This would show a prompt including the possible reasons for leave as shown in the image below.
