The Hubzone API is live
Records of contacts, companies, deals, tickets, products and orders can be listed, searched, read, created and changed with scoped keys. Phone calls can be logged. Custom events can be sent with an event key. The MCP server lets assistants such as Claude use the same keys. Limits are per key and per kind of call, with X-RateLimit headers.
