This call is asynchronous, it initiates an eligibility search and returns a UID assigned to this request. The result will be returned in two ways:
Via active webhooks once available - preferred. Request UID will be included in payload.
By calling the “Eligibility Result” endpoint - only to be used as fallback. Request UID is required.
If specifying a UID, ensure it is unique. If omitted, one will be generated automatically and included in the response for this API call.The response will contain the request UID or a validation error.
