Some products and features are in the process of being renamed. Generative playbook and flow features are also being migrated to a single consolidated console. See the details.
Processes a natural language query and returns structured, actionable data as a result through server-side streaming. Server-side streaming allows Dialogflow to send partial responses earlier in a single request.
HTTP request
POST https://{endpoint}/v3/{session=projects/*/locations/*/agents/*/environments/*/sessions/*}:serverStreamingDetectIntent
Required. The name of the session this query is sent to. Format: projects/<ProjectID>/locations/<LocationID>/agents/<AgentID>/sessions/<Session
ID> or projects/<ProjectID>/locations/<LocationID>/agents/<AgentID>/environments/<EnvironmentID>/sessions/<SessionID>. If Environment ID is not specified, we assume default 'draft' environment. It's up to the API caller to choose an appropriate Session ID. It can be a random number or some type of session identifiers (preferably hashed). The length of the Session ID must not exceed 36 characters.
