In a recent update, WebEngage has standardized the display names for 95 system events across all engagement channels.
Backend event names are unchanged. Only what you see in the WebEngage UI has been updated. APIs, webhooks, User Event Stream, and data exports are unaffected.
Event display names were inconsistent in two ways:
- Names didn't accurately reflect the delivery lifecycle step. For example, "Email Accepted" (the message was handed to the ESP, not delivered) is now "Email Sent to ESP."
- Naming conventions varied across channels. The language is now aligned across Email, SMS, WhatsApp, RCS, Viber, Push, Web Push, On-site, and Inbox.

Will my existing segments break?
No. Segments and filters reference events by backend name internally. Backend names are unchanged, so no existing segments, funnels, journeys, or alerts are affected.
What about the API and webhooks?
No change. Backend names used in all API calls, webhook payloads, and data exports are unchanged.
What about User Event Stream?
The new display names are now visible in User Event Stream. Old display names are no longer shown.
