You can set your credentials on a global basis as well as on a per-API basis. See each individual API section below to see how you can auth on a per-API-basis. This is useful if you want to use different accounts for different Google Cloud services. + +### On Google Compute Engine + +If you are running this client on Google Compute Engine, we handle authentication for you with no configuration. You just need to make sure that when you [set up the GCE instance][gce-how-to], you add the correct scopes for the APIs you want to access. + +``` js +// Authenticating on a global basis. +var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123' + +var bigQuery = require('@google-cloud/bigquery')({ + projectId: projectId +}); + +// ...you're good to go! See the next section to get started using the API. +``` + +### Elsewhere + +If you are not running this client on Google Compute Engine, you need a Google Developers service account. To create a service account: + +1. Visit the [Google Developers Console][dev-console]. +2. Create a new project or click on an existing project. +3. Navigate to **APIs & auth** > **APIs section** and turn on the following APIs (you may need to enable billing in order to use these services): + * Google Cloud Datastore API + * Google Cloud Storage + * Google Cloud Storage JSON API +4. Navigate to **APIs & auth** > **Credentials** and then: + * If you want to use a new service account, click on **Create new Client ID** and select **Service account**. After the account is created, you will be prompted to download the JSON key file that the library uses to authenticate your requests. + * If you want to generate a new key for an existing service account, click on **Generate new JSON key** and download the JSON key file. + +``` js +var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123' + +var bigQuery = require('@google-cloud/bigquery')({ + projectId: projectId, + + // The path to your key file: + keyFilename: '/path/to/keyfile.json' + + // Or the contents of the key file: + credentials: require('./path/to/keyfile.json') +}); + +// ...you're good to go!
