Given a workflow specified by the header, the API returns a list of required and optional inputs for running an evaluation through the designated workflow. Alloy's API is dynamic, and thus the input parameters vary depending on which services are run and how the workflow is configured. Hitting the GET /parameters endpoint will show exactly what your initial POST /evaluations request to the Alloy API should look like. All attributes will either be always required, conditionally required, or optional. For instance, in the example here, you either have to pass document_ssn OR both document_license and document_license_state. Note that this response body is just an example, and the exact parameters of your workflow version will vary.
