About this guide

PulseGate centralizes business messaging for SMS and popular OTT channels including WhatsApp, Facebook Messenger, Instagram DM, and Telegram. Connect providers like Twilio or Meta Cloud API once, then send and receive through a single, normalized interface. PulseGate tracks delivery receipts, applies rate-limit aware retries, and surfaces errors with one-click safe requeue.

Admins manage connectors, numbers/senders, WhatsApp templates, and compliance (opt-in/opt-out, quiet hours). Apps such as LiveConnect and Agent Desk consume clean events and message states without worrying about vendor quirks.

Built for reliability and scale with queues, backoff, DLQs, and health dashboards.
