Fxiaoke Open API v2
The Fxiaoke Open API v2 exposes CRM business objects (accounts, contacts, leads, opportunities, products, orders) and common services (approval workflows, directory/contact sync, business-data sync) as a JSON-over-HTTP POST RPC interface. Enterprise apps authenticate with appId + appSecret + permanentCode to obtain a company/app access token, then call object CRUD and query operations. Responses use an errorCode / errorMessage / traceId envelope.
