// Package documentai provides access to the Cloud Document AI API.
//
// For product documentation, see: https://cloud.google.com/document-ai/docs/
//
// Creating a client
//
// Usage example:
//
//   import "google.golang.org/api/documentai/v1beta2"
//   ...
//   ctx := context.Background()
//   documentaiService, err := documentai.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for authentication.
//
// For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.
//
// Other authentication options
//
// To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:
//
//   documentaiService, err := documentai.NewService(ctx, option.WithAPIKey("AIza..."))
//
// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:
//
//   config := &oauth2.Config{...}
//   // ...
//   token, err := config.Exchange(ctx, ...)
//   documentaiService, err := documentai.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
//
// See https://godoc.org/google.golang.org/api/option/ for details on options.
