# Intro to JSON Forms

Most config variables are singleton - that is, they prompt for a single string or boolean value, or a single selection from a dropdown.

JSON Forms are a powerful tool for building dynamic user interfaces in your integrations. They allow you to create complex forms that can capture multiple pieces of information from your users in a structured way. This is especially useful when you need to collect data that has a specific format, such as an array of objects or a nested structure.

In this video we create a JSON Form that prompts a user for several types of data, we present additional fields when the user selects a specific option, and we add some validation to ensure the user enters valid selections.
