Generates an OAuth 2.0 access token for a service account.

Scopes

You will need authorization for the https://www.googleapis.com/auth/cloud-platform scope to make a valid call.

If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: iamcredentials1 --scope <scope> projects service-accounts-generate-access-token ...

Required Scalar Argument

  • <name> (string)
    • Required. The resource name of the service account for which the credentials are requested, in the following format: projects/-/serviceAccounts/{ACCOUNT_EMAIL_OR_UNIQUEID}. The - wildcard character is required; replacing it with a project ID is invalid.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

GenerateAccessTokenRequest:
  delegates: [string]
  lifetime: string
  scope: [string]

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r . delegates=et
    • The sequence of service accounts in a delegation chain. This field is required for delegated requests. For direct requests, which are more common, do not specify this field. Each service account must be granted the roles/iam.serviceAccountTokenCreator role on its next service account in the chain. The last service account in the chain must be granted the roles/iam.serviceAccountTokenCreator role on the service account that is specified in the name field of the request. The delegates must have the following format: projects/-/serviceAccounts/{ACCOUNT_EMAIL_OR_UNIQUEID}. The - wildcard character is required; replacing it with a project ID is invalid.
    • Each invocation of this argument appends the given value to the array.
  • lifetime=magna
    • The desired lifetime duration of the access token in seconds. By default, the maximum allowed value is 1 hour. To set a lifetime of up to 12 hours, you can add the service account as an allowed value in an Organization Policy that enforces the constraints/iam.allowServiceAccountCredentialLifetimeExtension constraint. See detailed instructions at https://cloud.google.com/iam/help/credentials/lifetime If a value is not specified, the token's lifetime will be set to a default value of 1 hour.
  • scope=no
    • Required. Code to identify the scopes to be included in the OAuth 2.0 access token. See https://developers.google.com/identity/protocols/googlescopes for more information. At least one value required.
    • Each invocation of this argument appends the given value to the array.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional General Properties

The following properties can configure any call, and are not specific to this method.

  • -p $-xgafv=string

    • V1 error format.

  • -p access-token=string

    • OAuth access token.

  • -p alt=string

    • Data format for response.

  • -p callback=string

    • JSONP

  • -p fields=string

    • Selector specifying which fields to include in a partial response.

  • -p key=string

    • API key. Your API key identifies your project and provides you with API access, quota, and reports. Required unless you provide an OAuth 2.0 token.

  • -p oauth-token=string

    • OAuth 2.0 token for the current user.

  • -p pretty-print=boolean

    • Returns response with indentations and line breaks.

  • -p quota-user=string

    • Available to use for quota purposes for server-side applications. Can be any arbitrary string assigned to a user, but should not exceed 40 characters.

  • -p upload-type=string

    • Legacy upload protocol for media (e.g. "media", "multipart").

  • -p upload-protocol=string

    • Upload protocol for media (e.g. "raw", "multipart").
