Google APIs Client Library for Go

Authorization

By default, each API will use Google Application Default Credentials for authorization credentials used in calling the API endpoints. This will allow your application to run in many environments without requiring explicit configuration.

// import "google.golang.org/api/sheets/v4"
client, err := sheets.NewService(ctx)

To authorize using a JSON key file, pass option.WithCredentialsFile to the NewService function of the desired package. For example:

client, err := sheets.NewService(ctx, option.WithCredentialsFile("path/to/keyfile.json"))

You can exert more control over authorization by using the golang.org/x/oauth2 package to create an oauth2.TokenSource. Then pass option.WithTokenSource to the NewService function:

tokenSource := ...
svc, err := sheets.NewService(ctx, option.WithTokenSource(tokenSource))
