Vertafore AMS360 EMS API
The newest and preferred REST API for AMS360, the flagship property and casualty agency management system. It exposes agency data as REST resources - Customers, Policies, Service Agreements, Invoices, Billing, Deposits, and Personnel - secured with OAuth Bearer tokens. Public tutorials show the sandbox base host api-sandbox.vertafore.com and a Customers endpoint under /authgrant/v1/api; the full resource surface is documented behind the gated Developer Portal, so endpoints here are modeled rather than harvested.
