About Ha Tang
Ha Tang is a customer support, email and payments platform for Vietnamese businesses and software teams. Its shared inbox brings together Zalo (Official Account and personal), Facebook Messenger, Instagram, TikTok, WhatsApp, email and live chat on websites and in mobile apps. An AI assistant answers from company knowledge, follows situation rules, drafts orders and hands conversations to human agents. The platform matches VietQR bank transfers to orders and issues e-invoices when orders are paid. Its email module supports transactional delivery through a REST API and SMTP, verified domains, inbound email and team groups. Developers can use REST APIs, webhooks, SDKs for Node, Flutter, iOS and Android, and an MCP server. Agents work from a web dashboard and native iOS, Android and macOS apps.
