It's incredibly easy to get authenticated and start using Google's APIs. 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.
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, you add the correct scopes for the APIs you want to access.
// Authenticating on a global basis.
var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123'
var vision = require('@google-cloud/vision')({
projectId: projectId
});
// ...you're good to go!
If you are not running this client on Google Compute Engine, you need a Google Developers service account. To create a service account:
var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123'
var vision = require('@google-cloud/vision')({
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!
