{"id":5239,"library":"google-cloud-dialogflow-cx","title":"Google Cloud Dialogflow CX","description":"The `google-cloud-dialogflow-cx` client library provides Pythonic access to the Google Cloud Dialogflow CX API. Dialogflow CX is a conversational AI platform designed for building advanced virtual agents with complex, multi-turn conversations using a visual state-machine approach. This library facilitates interaction with Dialogflow CX agents, sessions, intents, flows, and other resources. It is part of the larger `google-cloud-python` ecosystem, which typically sees frequent updates and releases.","status":"active","version":"2.5.0","language":"en","source_language":"en","source_url":"https://github.com/googleapis/google-cloud-python/tree/main/packages/google-cloud-dialogflow-cx","tags":["google cloud","dialogflow","conversational ai","chatbot","nlp","client library"],"install":[{"cmd":"pip install google-cloud-dialogflow-cx","lang":"bash","label":"Install stable version"}],"dependencies":[{"reason":"Core utilities for Google Cloud client libraries.","package":"google-api-core","optional":false},{"reason":"Handles authentication with Google Cloud services.","package":"google-auth","optional":false},{"reason":"Provides Pythonic wrappers around raw Protobuf messages.","package":"proto-plus","optional":false},{"reason":"Underlying Protobuf serialization library.","package":"protobuf","optional":false}],"imports":[{"note":"Use the stable v3 client unless explicitly needing beta features.
