3 Steps to Automated Messaging
Define Your Trigger Event
Choose from pre-built events (abandoned cart, sign-up, purchase) or create custom webhook triggers from your backend systems.
Configure Your Template & Delay
Select a pre-approved WhatsApp template, set personalization variables, and configure the delay (e.g., 1 hour after cart abandonment).
Activate & Monitor
Turn on your trigger and monitor performance in real-time. Track delivery, opens, clicks, and conversion rates from your dashboard.
Event Triggers vs. Polling Systems vs. Manual Webhooks
Compare setup overhead, network latency, and infrastructure resource costs for event automation.
| Comparison Point | Real-time Event Triggers | Cron Polling Systems | Manual Direct Webhooks |
|---|---|---|---|
| Message Latency | < 1 second (Direct push) | Minutes to hours (Batch run) | < 1 second (Direct hook) |
| Development Effort | Low (Configure on UI/API) | Medium (Write scheduler logic) | High (Handle edge failures) |
| Server Load Overhead | Minimal (Event-driven) | High (Heavy periodic DB scans) | Minimal (Push updates) |
| Error Fallback Handling | ✓ (Built-in retry queues) | ✗ (Manual correction needed) | ✗ (Requires custom script queues) |

Can I set delays for triggered messages?
Yes. You can configure delays from 0 seconds (instant) up to 72 hours after the trigger event. For example, send an abandoned cart reminder 1 hour after the user left your site, followed by a second reminder at 24 hours with a discount offer.
