Altrata Matching API
Asynchronous bulk matching of a customer dataset against the Altrata dataset. Submit a personsMatch or organizations mutation, receive a requestId, poll until matched, then page the results as unique / possible / no match. Accepts wxPersonId — the Wealth-X person identifier — as a first-class match input, which is how legacy Wealth-X identity resolves into the unified model. 6MB maximum per HTTP POST.
