These are your primary tools for gathering data during a conversation.

*** #### **Raw Input** This card asks the user an open-ended question and captures their response as free-form text. It's ideal for questions that require a unique, typed answer, like a name or a detailed request. * **Question to ask**: The message the user will see. * **Let AI Process your input**: A toggle to let the AI analyze and understand the user's free text response. * **Regex (Regular Expression)**: An advanced option to validate the user's input with a specific pattern (e.g., an email address format or a phone number). * **Store in variable**: Saves the user's response in a variable for later use in the flow.

*** #### **Single Choice** This card presents a set of options from which the user can select only one. * **Question to ask**: The message the user will see. * **Choices**: The list of options you want to present to the user. * **Use Interactive WhatsApp message**: A toggle to format the choices as interactive buttons when the chatbot is integrated with WhatsApp. * **Store in variable**: Saves the user's selection in a variable for later use in the flow.

*** #### **Multiple Choice** This card allows the user to select one or more options from a list. * **Question to ask**: The message the user will see. * **Choices**: The list of options you want to present. * **Use Interactive WhatsApp message**: A toggle to format the choices as an interactive WhatsApp message. * **Store in variable**: Saves the user's selections in a variable.

*** #### **Dropdown** This card provides a compact menu for the user to select a single option from a list. * **Question to ask**: The message the user will see. * **Choices**: The list of options to be included in the dropdown menu. * **File Input**: Use this option when you have **a large number of dropdown choices** that would be tedious to add manually. Instead of typing them one by one, you can upload a **CSV file** where the first column contains the list of options. > **How it works:** Once you upload the CSV, each row in the first column is automatically converted into a dropdown option. The file must **not contain headers**. This allows you to quickly manage and update dropdowns without manual entry. * **Use Interactive WhatsApp message**: A toggle to format the choices as an interactive WhatsApp message. * **Store in variable**: Saves the user's selection in a variable.

*** #### **Image/Document Upload** This card enables the user to upload files, such as images or documents, directly into the conversation. * **Question to ask**: The message the user will see.

*** #### **Location** This card prompts the user to share their geographical location. * **Question to ask**: The message the user will see. * **Store in variable**: Saves the user's location data in a variable.

#### **Call Permission Request** This card prompts the user to grant permission for voice calls. (**Note:** This is a WhatsApp-exclusive card). * **Message:** The text displayed to the user immediately above the call permission request.
