To help you\nget started, we offer [code samples](/manufacturers/libraries) in Java and .NET.\n\nThis guide will help you create your first application using the Manufacturer\nCenter API. Before you can start coding, there are a few things you need to do.\n\nREST Support\n------------\n\nOur REST API supports basic CRUD operations for 2 different types of resources:\n\n- [Product](/manufacturers/reference/rest/v1/accounts.products) for Brand Owners and Data Partners.\n- And [ProductCertification](/manufacturers/reference/rest/v1/accounts.languages.productCertifications) for Certification Bodies.\n\nThe rest of this documentation will be written mainly for [Product](/manufacturers/reference/rest/v1/accounts.products) but the process should be similar for [ProductCertification](/manufacturers/reference/rest/v1/accounts.languages.productCertifications).\n\nSet up your Manufacturer Center Account\n---------------------------------------\n\n1. Create a [Manufacturer Center\n Account](//support.google.com/manufacturers/answer/7064831).\n\n | **Note:** Certification Body users can't create an account this way but need to contact our support directly.\n2. Be sure to remember which email you used to create this Manufacturer Center\n account, as you will need that later. In the screenshots, you'll see it\n represented as **manufacturer_user@example.com**.\n\nMake your first API request (without a line of code!)\n-----------------------------------------------------\n\n1. Head over to the [APIs\n Explorer](/manufacturers/reference/rest/v1/accounts.products/list#try-it) in\n our developer documentation for `Accounts.Products.list`.\n\n2. Ensure that the logged in Google account is listed in the 'Users' setting\n in the Settings tab.\n\n3. In the APIs Explorer, make sure that **Google OAuth 2.0** is selected in the\n **Authentication** drop-down menu:\n\n4. Enter `accounts/{account_id}`, replacing `{account_id}` with your\n Manufacturer ID from your Manufacturer Center account, into the 'parent'\n field of the form, and click **Execute**.\n\n | **Note:** If you have not previously granted OAuth2 permission, you will now be asked to authorize the call.\n5. You should see a successful response. Congratulations! You've made your\n first Manufacturer Center API request.\n\n6. If you have no products in your Manufacturer Center yet, there won't be any\n in the list. At this point, you can hop to other requests and take a look at\n what they do. Since this is a RESTful API, all requests work similarly. A\n good next step, once you have products, is to try\n [`Accounts.Products.get`](/manufacturers/reference/rest/v1/accounts.products/get#try-it).\n\nCreate a Google API Console Project\n-----------------------------------\n\nRequests to the Manufacturer Center API are made through your API Console project. Here we assume you will be accessing your own\nManufacturer Center account, so we suggest using [service\naccounts](/identity/protocols/OAuth2ServiceAccount) to simplify the\nauthentication flow. See the [Service\nAccounts](/manufacturers/how-tos/service-accounts) Guide for details on how to\nset up a new service account to use with your Manufacturer Center account.\n| **Note:** If you are interested in making calls on behalf of clients with their own Manufacturer Center accounts, then see the [Authorize\n| Requests](/manufacturers/how-tos/authorizing) guide.\n\nYour first authorized API request using Java\n--------------------------------------------\n\nNow that you've set up a service account and added the service account ID to\nyour Manufacturer Center account, you can access your account using the\navailable [Samples code](/manufacturers/libraries). This guide uses the Java\nsamples to demonstrate using the API.\n\n1. Install [Apache Maven](https://maven.apache.org/), if you haven't already.\n\n2. Download our [Shopping\n samples](//github.com/googleads/googleads-shopping-samples/) from our GitHub\n page.\n\n3. From within the `java` subdirectory, build the Java samples:\n\n $ mvn compile\n\n4. Now run the `ProductsListSample` (the example for [ProductCertification](/manufacturers/reference/rest/v1/accounts.languages.productCertifications) would be `ListProductCertificationsSample`) code:\n\n $ mvn exec:java -Dexec.mainClass=\"shopping.manufacturers.v1.samples.products.ProductsListSample\"\n\n5. If you haven't followed the configuration directions in the README\n accompanying the source files, you will get an error that no sample\n configuration could be found. Follow the directions in the README to create\n the configuration directory and to populate it with the appropriate\n information. The JSON file you downloaded while setting up your service\n account should be placed in that directory with the filename\n `service-account.json`. Remember to tell the code where your file is by\n setting the following environment variable.\n\n export GOOGLE_APPLICATION_CREDENTIALS=\u003cPath to your JSON credentials file\u003e\n\n6. Now that you have set up the samples configuration, run the\n `ProductsListSample` code again.\n\n $ mvn exec:java -Dexec.mainClass=\"shopping.manufacturers.v1.samples.products.ProductsListSample\"\n\n7. At this point, the Java program should finish executing, and print out\n either a list of products that it found, or a message that there were no\n products in your account. If you get an error such as \"User cannot access\n account 1234567890\", it's most likely because you have not set up the\n service account user as an authorized user in Manufacturer Center. From the\n API's standpoint, the API Console project sent a request on\n behalf of a user who was not on the list of authorized Manufacturer Center\n administrators, so it would, of course, reject that request.\n\n8. You can experiment with running `ProductsListSample` as many times as you\n want, since it is a read-only request. You can also explore the other\n samples that we've created for both Java and .NET."]]
