create_workflow#

Transfer.Client.create_workflow(**kwargs)#

Allows you to create a workflow with specified steps and step details the workflow invokes after file transfer completes. After creating a workflow, you can associate the workflow created with any transfer servers by specifying the workflow-details field in CreateServer and UpdateServer operations.

    - SourceFileLocation (string) –
      
      Specifies which file to use as input to the workflow step: either the output from the previous step, or the originally uploaded file for the workflow.
      - To use the previous file as the input, enter ${previous.file}. In this case, this workflow step uses the output file from the previous workflow step as input. This is the default value.
      - To use the originally uploaded file location as input for this step, enter ${original.file}.
    - OverwriteExisting (string) –
      
      A flag that indicates whether to overwrite an existing file of the same name. The default is FALSE.
      
      If the workflow is processing a file that has the same name as an existing file, the behavior is as follows:
      - If OverwriteExisting is TRUE, the existing file is replaced with the file being processed.
      - If OverwriteExisting is FALSE, nothing happens, and the workflow processing stops.
    - DestinationFileLocation (dict) – [REQUIRED]
      
      Specifies the location for the file being decrypted. Use ${Transfer:UserName} or ${Transfer:UploadDate} in this field to parametrize the destination prefix by username or uploaded date.
      - Set the value of DestinationFileLocation to ${Transfer:UserName} to decrypt uploaded files to an Amazon S3 bucket that is prefixed with the name of the Transfer Family user that uploaded the file.
      - Set the value of DestinationFileLocation to ${Transfer:UploadDate} to decrypt uploaded files to an Amazon S3 bucket that is prefixed with the date of the upload.
      Note
      The system resolves UploadDate to a date format of YYYY-MM-DD, based on the date the file is uploaded in UTC.
      - S3FileLocation (dict) –
