Addresses #393

Replace workflowId in request/response and returned a workflow object.

-        workflowId:
-          type: string
-          description: The URL that uniquely identifies the created workflow.
+        workflowData:


Hmm, I think just the workflow config should be returned here and it looks like this is something a little different with some additional metadata is here. Certainly an implementation could do more, but I think we should only say that the workflow config is returned (i.e,. the same thing you'd get if you did a GET on the workflow ID).

Suggested change

workflowData:

config:

This is a copy of what is returned by the GET workflowId as you are suggesting with the addition of the workflowId itself under the 'id' property as mentioned in the original issue.

Oh, I see we have a couple of mistakes in what's in the spec now then. There should be no workflowData property when creating a workflow, rather, the properties here:

vc-api/exchanges.yml

Lines 190 to 222 in 5efdafd

properties:

steps:

type: object

description: One or more steps required to complete an exchange on the workflow. Passing the steps object is REQUIRED.

properties:

stepName:

type: object

description: The name of the step.

properties:

step:

$ref: "#/components/schemas/WorkflowStep"

initialStep:

type: string

description: The step from the above set that the exchange starts on. Passing intialStep is REQUIRED.

controller:

type: string

description: The controller of the instance. Passing controller is OPTIONAL.

authorization:

type: string

description: Authorization scheme information (e.g., OAuth2 configuration). Passing authorization is OPTIONAL.

credentialTemplates:

type: array

description: One or more VC templates for issuance. Passing credentialTemplates is OPTIONAL.

items:

type: object

properties:

type:

type: string

template:

type: string

id:

type: string

description: The ID that will be used for the created workflow. Passing an ID is OPTIONAL.

Should just be the main top-level properties in the payload, this is the "config" for the workflow.

I also see that the GET workflowId section is inconsistent and adds that extra stepInformation bit -- which we should remove (collapse it down so its nested properties are moved up a level so it matches what should be in the above payload for creating the workflow).

I think this could be a potentially huge number of exchanges for a very popular workflow -- and it isn't part of the config, so we shouldn't do this as a requirement, though some implementation might return this kind of data if that is desirable/not problematic.

I think the stepInformation bit should be collapsed to what's in the config, i.e., I think steps and initialStep are nested here when they shouldn't be. See also note on "current exchanges".

This is a copy of the config of an existing workflow returned by the get workflowId route, could you provide an example of what the config should look like if this is not it?

When creating a workflow, the config is the payload, it is not nested under config. I think we should have a WorkflowConfig object that can be referenced and used here as the direct payload and in other places where a config property is used to express it along with other side-by-side properties (like in the response / potentially other places) this object type can just be referenced -- rather than duplicating its rather long schema description.

I don't expect this (exchanges) to ever be part of a WorkflowConfig -- and it may be very large in size anyway.

This PR was merged presuming that a WorkflowConfig object will be created to remove duplication of that object.

Added workflow response object to exchanges.yml
