Group Messaging, Overview

DropOnAir supports group messaging with full end-to-end encryption (E2EE) or cleartext mode. Groups are managed via REST API and messages are delivered in real time over the existing WebSocket connection.

How it works

• Create a group, specify a name and initial member list via the SDK or REST API
• Send messages, the SDK encrypts each message per-member (sender-side fan-out) for E2EE groups, or sends cleartext for public groups
• Receive messages, all online members receive the message via WebSocket; offline members get it on reconnect

Plan limits

Each plan defines limits for:

• maxGroupsPerApp, maximum number of groups per application
