Reference documentation and code samples for the Dialogflow v3 API class MatchIntentRequest.
Required. The name of the session this query is sent to.
Format:
projects/<ProjectID>/locations/<LocationID>/agents/<AgentID>/sessions/<SessionID>
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.
