This is the unified documentation for Retail API. This includes Recommendations AI, Retail Search, and the unified Retail console (which is applicable to both Recommendations AI and Retail Search users). To use the new console or Retail Search while they are in the restricted GA phase, submit a form here to contact Cloud sales. If you are using the v1beta version of Recommendations AI, migrate to the GA version: Migrating to the Retail API from beta.

To see documentation for only Recommendations AI and the Recommendations AI-only console, go to the How-to guides for Recommendations AI and the API reference documentation for Recommendations AI.

Method: projects.locations.catalogs.userEvents.collect

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.

HTTP request

GET https://retail.googleapis.com/v2/{parent=projects/*/locations/*/catalogs/*}/userEvents:collect

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
parent

string

Required. The parent catalog name, such as projects/1234/locations/global/catalogs/default_catalog.

Query parameters

Parameters
userEvent

string

Required. URL encoded UserEvent proto with a length limit of 2,000,000 characters.

uri

string

The URL including cgi-parameters but excluding the hash fragment with a length limit of 5,000 characters. This is often more useful than the referer URL, because many browsers only send the domain for 3rd party requests.

ets

string (int64 format)

The event timestamp in milliseconds. This prevents browser caching of otherwise identical get requests. The name is abbreviated to reduce the payload bytes.

Request body

The request body must be empty.

Response body

If successful, the response is a generic HTTP response whose format is defined by the method.
