Setting up dialogs in your bot builder to send out preset responses to customers is pretty straightforward. You can also dynamically populate values in your dialogs to help your customers with contextual responses.
The bot builder provides you with commonly used functions for your daily operations, such as fetching current date, separating strings by a delimiter, manipulating date and time, etc. These Functions act as placeholders and take care of populating values for these fields dynamically. What’s more, you can also define how you want each function to behave or collect information by declaring them as Inputs. The inputs are predefined for each function, and you can also use placeholders from other dialogs, API, or custom/default properties for each of these functions.
For example, you can ask your customer their name, and while saving it, you can use a function to ensure that it is saved in the title case. Listed below are the explanations for the functions offered by the bot builder. You can use the corresponding function in your dialog to dynamically populate values in your bot.
Functions can either be triggered by
- Navigating to a dialog > Input options > Functions
- Naviagating to a dialog > adding a condition > input option > Function
Note: The "Contains" function can only be used inside a condition as it is an evaluative function whose output is not needed for the dialogs.

We have only used a few formats in our examples. You can make use of any of the standardized date and time formats.
All the input fields can take inputs from existing placeholders, such as dialogs, APIs, and parameters. Similarly, you can use the output from any function as a placeholder elsewhere.
