         * Set a specified branch id as default branch. API methods such as SearchService.Search, ProductService.GetProduct, ProductService.ListProducts will treat requests using "default_branch" to the actual branch id set as default. For example, if `projects/x/locations/x/catalogs/x/branches/1` is set as default, setting SearchRequest.branch to `projects/x/locations/x/catalogs/x/branches/default_branch` is equivalent to setting SearchRequest.branch to `projects/x/locations/x/catalogs/x/branches/1`. Using multiple branches can be useful when developers would like to have a staging branch to test and verify for future usage. When it becomes ready, developers switch on the staging branch using this API while keeping using `projects/x/locations/x/catalogs/x/branches/default_branch` as SearchRequest.branch to route the traffic to this staging branch. CAUTION: If you have live predict/search traffic, switching the default branch could potentially cause outages if the ID space of the new branch is very different from the old one. More specifically: * PredictionService will only return product IDs from branch {newBranch\}. * SearchService will only return product IDs from branch {newBranch\} (if branch is not explicitly set). * UserEventService will only join events with products from branch {newBranch\}. This feature is only available for users who have Retail Search enabled.

This process is asynchronous and does not require the Product to exist before updating fulfillment information. If the request is valid, the update will be enqueued and processed downstream. As a consequence, when a response is returned, updates are not immediately manifested in the Product queried by GetProduct or ListProducts.

Pre-existing inventory information can only be updated with SetInventory, AddFulfillmentPlaces, and RemoveFulfillmentPlaces. This feature is only available for users who have Retail Search enabled.

        /**
         * Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns `UNIMPLEMENTED`. NOTE: the `name` binding allows API services to override the binding to use different resource name schemes, such as `users/x/operations`. To override the binding, API services can add a binding such as `"/v1/{name=users/x\}/operations"` to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.
         * @example
         * ```js
         * // Before running the sample:
         * // - Enable the API at:
         * //   https://console.developers.google.com/apis/api/retail.googleapis.com
         * // - Login into gcloud by running:
         * //   `$ gcloud auth application-default login`
         * // - Install the npm module by running:
         * //   `$ npm install googleapis`
         *
         * const {google} = require('googleapis');
         * const retail = google.retail('v2');
         *
         * async function main() {
         *   const auth = new google.auth.GoogleAuth({
         *     // Scopes can be specified either as an array or as a single, space-delimited string.
         *     scopes: ['https://www.googleapis.com/auth/cloud-platform'],
         *   });
         *
         *   // Acquire an auth client, and bind it to all future calls
         *   const authClient = await auth.getClient();
         *   google.options({auth: authClient});
         *
         *   // Do the magic
         *   const res = await retail.projects.locations.operations.list({
         *     // The standard list filter.
         *     filter: 'placeholder-value',

         *     name: 'projects/my-project/locations/my-location',
         *     // The standard list page size.
         *     pageSize: 'placeholder-value',
         *     // The standard list page token.
         *     pageToken: 'placeholder-value',
         *   });
         *   console.log(res.data);

         *   // }
         * }
         *
         * main().catch(e => {
         *   console.error(e);
         *   throw e;
         * });
         *
         * ```
         *
         * @param params - Parameters for request
         * @param options - Optionally override request options, such as `url`, `method`, and `encoding`.
         * @param callback - Optional callback that handles the response.
         * @returns A promise if used with async/await, or void if used with a callback.
