 def create_transfer_config( self, parent, transfer_config, authorization_code=None, retry=google.api_core.gapic_v1.method.DEFAULT, timeout=google.api_core.gapic_v1.method.DEFAULT, metadata=None, ):
 """ Creates a new data transfer configuration. Example: Args: parent (str):
 The BigQuery project id where the transfer configuration should be created. Must be in the format /projects/{project\_id}/locations/{location\_id} If specified location and location of the destination bigquery dataset do not match - the request will fail. transfer_config (Union[dict, ~google.cloud.bigquery_datatransfer_v1.types.TransferConfig]):
 Data transfer configuration to create. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.bigquery_datatransfer_v1.types.TransferConfig` authorization_code (str):
 Optional OAuth2 authorization code to use with this transfer configuration. This is required if new credentials are needed, as indicated by ``CheckValidCreds``. In order to obtain authorization\_code, please make a request to https://www.gstatic.com/bigquerydatatransfer/oauthz/auth?client\_id=&scope=<data\_source\_scopes>&redirect\_uri=<redirect\_uri> - client\_id should be OAuth client\_id of BigQuery DTS API for the given data source returned by ListDataSources method. - data\_source\_scopes are the scopes returned by ListDataSources method. - redirect\_uri is an optional parameter. If not specified, then authorization code is posted to the opener of authorization flow window. Otherwise it will be sent to the redirect uri. A special value of urn:ietf:wg:oauth:2.0:oob means that authorization code should be returned in the title bar of the browser, with the page text prompting the user to copy the code and paste it in the application. retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Returns: A :class:`~google.cloud.bigquery_datatransfer_v1.types.TransferConfig` instance. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
