uri

The uri of a YAML workflow document file stored in Amazon S3. This must be an S3 URL (s3://bucket/key), and you must have permission to access the S3 bucket it points to. A workflow document that you provide from Amazon S3 can be up to your service quota for workflow size.

Alternatively, you can specify the YAML document inline, using the workflow data property. You must specify exactly one of the data or uri properties.
