Genesys Cloud's Detect Intent action enables automated intent detection and handling during bot interactions. The feature allows users to create and manage intents through the Natural Language Understanding menu, with Architect automatically generating paths for each detected intent. For email flows, the system analyzes the email body rather than the subject line. The action requires a name for identification in the flow structure and stores matching intent information in a variable, which can be utilized within Decision or Switch actions and Send Auto Reply responses.
