|
|
2. ✅ Process integration events from external systems automatically
|
|
3. ✅ Complete journey stages based on event triggers
|
|
4. ✅ Automatically create and send stage-specific surveys
|
|
5. ✅ Deliver surveys via SMS, WhatsApp, or Email
|
|
6. ✅ Collect and score survey responses
|
|
7. ✅ Detect negative feedback for action creation
|
|
8. ✅ Maintain complete audit trail
|
