Develop with chatt2.me Hub

Build authenticated integrations for customer communication, automation, and operations.

API and authentication

Create an application and use its active API key. Keys are bound to one application, and only endpoints that explicitly accept an API key can use them; Hub has no anonymous business operations.

Webhooks and sandbox

Receive customer-message and delivery events with webhooks, then validate channel behavior in a sandbox before production. This keeps integration work observable and reversible.

Documentation MCP

Use the public documentation MCP server to search with docs_search and retrieve returned pages with docs_fetch. The MCP server exposes public documentation only and requires no API key.
