ShomoyChat
WhatsApp API for OTP, Alerts & Customer Chat
Your own WhatsApp number as a full REST API — send OTPs, order notifications and auto-replies from your website or n8n. bKash payable, Dhaka-based support.
Overview
ShomoyChat turns the WhatsApp number you already own into a developer API. Scan one QR in your tenant dashboard, get your own wag_ API key, and start sending — OTPs for your signup flow, order confirmations for your shop, abandoned-cart recovery, and live support chat. Every tenant is isolated: your own session, your own key, your own message history. Best for transactional messaging — OTP, order updates, customer support. Not intended for bulk cold marketing (unofficial WhatsApp Web API; numbers sending spam risk bans).
