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.

[REQUIRED]
Specifies the details for the steps that are in the specified workflow.
The TYPE specifies which of the following actions is being taken for this step.
COPY - Copy the file to another location.CUSTOM - Perform a custom step with an Lambda function target.DECRYPT - Decrypt a file that was encrypted before it was uploaded.DELETE - Delete the file.TAG - Add a tag to the file.Note
Currently, copying and tagging are supported only on S3.
For file location, you specify either the Amazon S3 bucket and key, or the Amazon EFS file system ID and path.
The basic building block of a workflow.
Currently, the following step types are supported.
COPY - Copy the file to another location.CUSTOM - Perform a custom step with an Lambda function target.DECRYPT - Decrypt a file that was encrypted before it was uploaded.DELETE - Delete the file.TAG - Add a tag to the file.Details for a step that performs a file copy.

Timeout, in seconds, for the step.
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.

The name of the step, used as an identifier.
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.
${previous.file} . In this case, this workflow step uses the output file from the previous workflow step as input. This is the default value.${original.file} .Details for a step that creates one or more tags.
You specify one or more tags. Each tag contains a key-value pair.

Consists of the following values:
FALSE .The name of the step, used as an identifier.

The identifier of the file system, assigned by Amazon EFS.
The pathname for the folder being used by a workflow.
Specifies the steps (actions) to take if errors are encountered during execution of the workflow.
Note
For custom steps, the lambda function needs to send FAILURE to the call back API to kick off the exception steps. Additionally, if the lambda does not send SUCCESS before it times out, the exception steps are executed.

Creates a key-value pair for a specific resource. Tags are metadata that you can use to search for and group a resource for various purposes. You can apply tags to servers, users, and roles. A tag key can take more than one value. For example, to group servers for accounting purposes, you might create a tag called Group and assign the values Research and Accounting to that group.

Contains one or more values that you assigned to the key name you create.
