For example, in the CreateAsset activity, which requires the user to specify the id for the new asset, they can specify $autoId instead.

String Intrapolation

In any of the values in the workflow, support basic javascript style string intrapolation are supported. For example, in the RaiseEvent activity, message field, the following is supported – “Approval request raised for invoice: ${input.data.invoiceId}”

Every activity in the workflow will have a human readable id which is autogenerated by default, but can be modified by the user.

This id can then be used by the customer in subsequent steps to refer to the output generated as part of that activity. For e.g. $ReadAsset1.output will have the entire object returned by ReadAsset1 activity within it.
