This is the simple REST client for Vertex AI Search for commerce API V2. Simple REST clients are Ruby client libraries that provide access to Google services via their HTTP REST API endpoints. These libraries are generated and updated automatically based on the discovery documents published by the service, and they handle most concerns such as authentication, pagination, retry, timeouts, and logging. You can use this client to access the Vertex AI Search for commerce API, but note that some services may provide a separate modern client that is easier to use.
