Standard API Parameters

The following query parameters can be used with all methods and all resources in the Cloud Spanner API.

NOTES (on auth tokens):

  1. You must send an authorization token with every request that requires an OAuth scope. OAuth 2.0 is the only supported authorization protocol.
  2. You can provide an OAuth 2.0 token with any request in one of two ways:
    • Using the access_token query parameter like this: ?access_token=oauth2-token
    • Using the HTTP Authorization header like this: Authorization: Bearer oauth2-token

All parameters are optional except where noted.
