deleteContexts(parent, x__xgafv=None)

Deletes all active contexts in the specified session.

Args:
  parent: string, Required. The name of the session to delete all contexts from. Format:
`projects//agent/sessions/` or `projects//agent/environments//users//sessions/`. If `Environment ID` is not specified we assume default 'draft'
environment. If `User ID` is not specified, we assume default '-' user. (required)
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # A generic empty message that you can re-use to avoid defining duplicated
      # empty messages in your APIs. A typical example is to use it as the request
      # or the response type of an API method. For instance:
      #
      #     service Foo {
      #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
      #     }
      #
      # The JSON representation for `Empty` is empty JSON object `{}`.
  }

detectIntent(session, body, x__xgafv=None)

Processes a natural language query and returns structured, actionable data
as a result. This method is not idempotent, because it may cause contexts
and session entity types to be updated, which in turn might affect
results of future queries.

Args:
  session: string, Required. The name of the session this query is sent to. Format:
`projects//agent/sessions/`, or
`projects//agent/environments//users//sessions/`. If `Environment ID` is not specified, we assume
default 'draft' environment. If `User ID` is not specified, we are using
"-". It’s up to the API caller to choose an appropriate `Session ID` and
`User Id`. They can be a random numbers or some type of user and session
identifiers (preferably hashed). The length of the `Session ID` and
`User ID` must not exceed 36 characters. (required)
  body: object, The request body. (required)
