How It Works​

The Detect Intent node integrates with Google Dialogflow to analyze user text input and detect the underlying intent. When executed, the node:

  1. Validates the provided inputs (Text, Credentials, Language, Project ID)
  2. Authenticates with Google Dialogflow using the provided credentials
  3. Sends the user's text input to Dialogflow for intent detection
  4. Receives and processes the query result from Dialogflow
  5. Returns the complete query result as the output

Requirements​

  • A valid Google Cloud account with Dialogflow API enabled
  • Valid Google Dialogflow credentials (service account key)
  • A configured Dialogflow agent
  • Valid Dialog Flow Project ID
  • User text input to analyze

Error Handling​

The node will return specific errors in the following cases:

  • Empty or invalid Text input
  • Empty or invalid Language selection
  • Empty or invalid Dialog Flow Project ID
  • Empty or invalid Google Dialogflow credentials
  • Google Dialogflow service errors

Usage Notes​

  • The Text input should be a natural language query from the user
  • The Language option should match the language of the Text input for best results
  • If no Session ID is provided, a unique ID will be generated automatically
  • The output contains the complete Dialogflow query result, including:
    • Detected intent name and confidence score
    • Fulfillment text
    • Parameters extracted from the query
    • Other metadata from the Dialogflow response
  • This node is typically used in chatbot or conversational AI applications
