API Console projects help you manage API\naccess and authentication for your Content API solution.\n\nManual steps\n------------\n\nThere are two ways you can authenticate to use the Content API for Shopping\ndepending on whose merchant accounts you need to access:\n\nAccess your own Merchant Center account\n: If you only need to access your account (and sub-accounts, if using a\n multi-client account), then we suggest using service accounts. See the\n [Service accounts](/shopping-content/guides/how-tos/service-accounts) guide for the steps to create a service account from the\n [Merchant Center](https://merchants.google.com).\n\nAccess other merchants' accounts\n: If you plan to manage other Merchant Center accounts as a third-party, see the\n [OAuth](/shopping-content/guides/how-tos/authorizing) guide.\n\nOnce you have the appropriate authentication tokens, you can test your\nauthentication setup with the [Shopping samples](https://github.com/googleads/googleads-shopping-samples), which support both service\naccount and OAuth2 client authentication. These samples use the\n[Content API client libraries](/shopping-content/guides/libraries), which we recommend using in your own\napplications if you're using a supported language. Otherwise, you can use the\n[REST API](/shopping-content/reference/rest/v2.1) directly.\n\nAutomatic steps\n---------------\n\nNot available for this process."]]
