Exchanges a credential that represents the resource owner's authorization for a Google-generated [OAuth 2.0 access token] (https://www.rfc-editor.org/rfc/rfc6749#section-5) or [refreshes an accesstoken] (https://www.rfc-editor.org/rfc/rfc6749#section-6) following [the OAuth 2.0 authorization framework] (https://tools.ietf.org/html/rfc8693) The credential can be one of the following: - An authorization code issued by the workforce identity federation authorization endpoint - A refresh token issued by this endpoint This endpoint is only meant to be called by the Google Cloud CLI. Also note that this API only accepts the authorization code issued for workforce pools.

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:

GoogleIdentityStsV1ExchangeOauthTokenRequest:
  client-id: string
  code: string
  code-verifier: string
  grant-type: string
  redirect-uri: string
  refresh-token: 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 . client-id=no
  • Optional. The client identifier for the OAuth 2.0 client that requested the provided token. It is REQUIRED when the [client] (https://www.rfc-editor.org/rfc/rfc6749#section-1.1) is not authenticating with the authorization server, i.e. when authentication method is [client authentication] (https://www.rfc-editor.org/rfc/rfc6749#section-3.2.1).
• code=ipsum
  • Optional. The authorization code that was previously from workforce identity federation's authorize endpoint. Required if the flow is authorization code flow, i.e. if grant_type is 'authorization_code'
• code-verifier=voluptua.
  • Optional. The code verifier for the PKCE request, Google Cloud CLI originally generates it before the authorization request. PKCE is used to protect authorization code from interception attacks. See https://www.rfc-editor.org/rfc/rfc7636#section-1.1 and https://www.rfc-editor.org/rfc/rfc7636#section-3. It is required when the flow is authorization code flow, i.e. if grant_type is 'authorization_code'
• grant-type=at
  • Required. The grant types are as follows: - 'authorization_code' : an authorization code flow, i.e. exchange of authorization code for the Oauth access token - 'refresh_token' : a refresh token flow, i.e. obtain a new access token by providing the refresh token. See https://www.rfc-editor.org/rfc/rfc6749#section-6
• redirect-uri=sanctus
  • Optional. redirect_url is required when the flow is authorization code flow i.e. if grant_type is authorization_code See https://www.rfc-editor.org/rfc/rfc6749#section-4.1.3
• refresh-token=sed
  • Optional. The Refresh token is the credential that is used to obtain a new access token when the current access token becomes invalid or expires. Required when using refresh token flow, i.e. if grant_type is 'refresh_token' See https://www.rfc-editor.org/rfc/rfc6749#section-1.5 and https://www.rfc-editor.org/rfc/rfc6749#section-6
• scope=amet.
  • Optional. An optional list of scopes that are requested for the token to be returned. See https://www.rfc-editor.org/rfc/rfc6749#section-3.3 Must be a list of space-delimited, case-sensitive strings. Note: Currently, the scopes in the request are not supported

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").
