        protos.google.cloud.retail.v2.ICollectUserEventRequest | undefined,
        {} | undefined
    ]>;

Writes a single user event from the browser. This uses a GET request to due to browser restriction of POST-ing to a 3rd party domain.

This method is used only by the Retail API JavaScript pixel and Google Tag Manager. Users should not call this method directly.

        protos.google.longrunning.IOperation | undefined,
        {} | undefined
    ]>;

Starts a user event rejoin operation with latest product catalog. Events will not be annotated with detailed product information if product is missing from the catalog at the time the user event is ingested, and these events are stored as unjoined events with a limited usage on training and serving. This method can be used to start a join operation on specified events with latest version of product catalog. It can also be used to correct events joined with the wrong product catalog. A rejoin operation can take hours or days to complete.

Parameters

request	`protos.google.cloud.retail.v2.IRejoinUserEventsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.
