Reference documentation and code samples for the Google Cloud Retail V2 Client class UserEventServiceClient.
Service Description: Service for ingesting end user actions on the customer website.
This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:
$userEventServiceClient = new UserEventServiceClient();
try {
$parent = 'parent';
$userEvent = 'user_event';
$response = $userEventServiceClient->collectUserEvent($parent, $userEvent);
} finally {
$userEventServiceClient->close();
}
Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.
Methods
catalogName
Formats a string containing the fully-qualified path to represent a catalog resource.
| Parameters | |
|---|---|
| Name | Description |
project |
string
|
location |
string
|
catalog |
string
|
| Returns | |
|---|---|
| Type | Description |
string | The formatted catalog resource. |
parseName
Parses a formatted name string and returns an associative array of the components in the name.
The following name formats are supported: Template: Pattern
- catalog: projects/{project}/locations/{location}/catalogs/{catalog}
The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.
| Parameters | |
|---|---|
| Name | Description |
formattedName |
string
The formatted name string |
template |
string
Optional name of template to match |
| Returns | |
|---|---|
| Type | Description |
array | An associative array from name component IDs to component values. |
getOperationsClient
Return an OperationsClient object with the same endpoint as $this.
| Returns | |
|---|---|
| Type | Description |
Google\ApiCore\LongRunning\OperationsClient | |
resumeOperation
Resume an existing long running operation that was previously started by a long running API method. If $methodName is not provided, or does not match a long running API method, then the operation can still be resumed, but the OperationResponse object will not deserialize the final response.
| Parameters | |
|---|---|
| Name | Description |
operationName |
string
The name of the long running operation |
methodName |
string
The name of the method used to start the operation |
| Returns | |
|---|---|
| Type | Description |
Google\ApiCore\OperationResponse | |
__construct
Constructor.
| Parameters | |
|---|---|
| Name | Description |
options |
array
Optional. Options for configuring the service API wrapper. |
↳ apiEndpoint |
string
The address of the API remote host. May optionally include the port, formatted as "
|
↳ credentials |
string|array|FetchAuthTokenInterface|CredentialsWrapper
The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored. |
↳ credentialsConfig |
array
Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() . |
↳ disableRetries |
bool
Determines whether or not retries defined by the client configuration should be disabled. Defaults to |
↳ clientConfig |
string|array
Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder. |
↳ transport |
string|TransportInterface
The transport used for executing network requests. May be either the string |
↳ transportConfig |
array
Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options. |
↳ clientCertSource |
callable
A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS. |
collectUserEvent
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.
| Parameters | |
|---|---|
| Name | Description |
parent |
string
Required. The parent catalog name, such as
|
userEvent |
string
Required. URL encoded UserEvent proto with a length limit of 2,000,000 characters. |
optionalArgs |
array
Optional. |
↳ prebuiltRule |
string
The prebuilt rule name that can convert a specific type of raw_json. For example: "default_schema/v1.0" |
↳ 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 |
int
The event timestamp in milliseconds. This prevents browser caching of otherwise identical get requests. The name is abbreviated to reduce the payload bytes. |
↳ rawJson |
string
An arbitrary serialized JSON string that contains necessary information that can comprise a user event. When this field is specified, the user_event field will be ignored. Note: line-delimited JSON is not supported, a single JSON only. |
↳ retrySettings |
RetrySettings|array
Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage. |
| Returns | |

rejoinUserEvents
Starts a user-event rejoin operation with latest product catalog. Events are not annotated with detailed product information for products that are missing from the catalog when the user event is ingested. These events are stored as unjoined events with limited usage on training and serving. You can use this method to start a join operation on specified events with the latest version of product catalog. You can also use this method to correct events joined with the wrong product catalog. A rejoin operation can take hours or days to complete.

parent |
string
Required. The parent catalog resource name, such as
