Using an auto-launched flow to capture details is the recommended method to consistently capture new caller details. An auto-launched flow is a type of flow that runs in the background without user interaction. An auto-launched flow can be triggered by various actions, such as creating a record, updating a field, clicking a button, or invoking a process. An auto-launched flow can perform various tasks, such as collecting inputs, updating records, creating records, or calling external services. Using an auto-launched flow to capture details can help ensure that support agents enter the necessary information for new callers, such as their name, email address, phone number, or reason for call.
