If the specified context already exists, overrides the context.

Args:

Format: `projects/&lt;Project ID&gt;/agent/sessions/&lt;Session ID&gt;` or
`projects/&lt;Project ID&gt;/agent/environments/&lt;Environment ID&gt;/users/&lt;User
ID&gt;/sessions/&lt;Session ID&gt;`.
If `Environment ID` is not specified, we assume default &#x27;draft&#x27;
environment. If `User ID` is not specified, we assume default &#x27;-&#x27; user. (required)
  body: object, The request body.

{ # Dialogflow contexts are similar to natural language context. If a person says
    # to you &quot;they are orange&quot;, you need context in order to understand what &quot;they&quot;
    # is referring to. Similarly, for Dialogflow to handle an end-user expression
    # like that, it needs to be provided with context in order to correctly match
    # an intent.
    # 
    # Using contexts, you can control the flow of a conversation. You can configure
    # contexts for an intent by setting input and output contexts, which are
    # identified by string names. When an intent is matched, any configured output
    # contexts for that intent become active. While any contexts are active,
    # Dialogflow is more likely to match intents that are configured with input
    # contexts that correspond to the currently active contexts.
    #

    # [Contexts guide](https://cloud.google.com/dialogflow/docs/contexts-overview).

  updateMask: string, Optional. The mask to control which fields get updated.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Dialogflow contexts are similar to natural language context. If a person says
      # to you &quot;they are orange&quot;, you need context in order to understand what &quot;they&quot;
      # is referring to. Similarly, for Dialogflow to handle an end-user expression
      # like that, it needs to be provided with context in order to correctly match
      # an intent.
      #
      # Using contexts, you can control the flow of a conversation. You can configure
      # contexts for an intent by setting input and output contexts, which are
      # identified by string names. When an intent is matched, any configured output
      # contexts for that intent become active. While any contexts are active,
      # Dialogflow is more likely to match intents that are configured with input
      # contexts that correspond to the currently active contexts.
      #
      # For more information about context, see the
      # [Contexts guide](https://cloud.google.com/dialogflow/docs/contexts-overview).
    &quot;parameters&quot;: { # Optional. The collection of parameters associated with this context.
