Real-Time Message Sync
SyncRivo relays messages across platforms in real time using native platform events, not polling. A message sent in Slack typically shows in Teams in seconds.
Why real-time matters in enterprise messaging
When two teams are collaborating across Slack and Teams during an incident, a long delay is not a minor inconvenience — it's a gap in coordination that can extend resolution time. Polling-based bridges are fine for async notifications, but real-time conversation needs event-driven delivery. SyncRivo receives channel messages through native platform event systems rather than polling.
How real-time sync works
- 1
Event subscription per platform
SyncRivo registers event listeners on each connected platform using the native event system: Slack Events API, Microsoft Bot Framework, Google Chat app events, Zoom Webhook Events, and Webex Webhook API.
- 2
Verify, translate and route
When an event arrives, SyncRivo verifies its signature, translates formatting, threads and @mentions for each destination, and routes it. Message content is not stored on the normal relay path.
- 3
Delivery to all connected destinations
If a channel is bridged to three platforms, SyncRivo posts the message to each connected destination, and replies from any of them flow back the same way.
- 4
Deduplication and loop prevention
Bot-generated messages are tagged with SyncRivo's bot identity and filtered from event processing, preventing infinite message loops while maintaining full bidirectional sync.
How Real-Time Sync works in SyncRivo
Webhook ingestion and signature verification
SyncRivo is hosted in the US on Google Cloud (us-central1) and receives inbound events over TLS. Every request carries a platform-specific signature or token — Slack x-slack-signature, Bot Framework JWT, Google Chat bearer token, Zoom signature, Webex webhook signature — verified before the event enters the routing pipeline. Duplicate events are filtered so platform retries do not produce duplicate deliveries downstream.
Threads, edits and loop prevention
SyncRivo keeps the source and destination message IDs for each relayed message, so thread replies, edits, deletes and reactions reach the right message on every platform. Messages SyncRivo posts are recognized and not relayed back, which prevents message loops while keeping sync bidirectional.
Delivery and retries
Outbound delivery uses each platform's API (Slack chat.postMessage, Teams Bot Framework, Google Chat spaces.messages, Zoom Team Chat messages, Webex /messages). Messages typically arrive within seconds. If an in-place edit or delete cannot be applied, a notice is posted instead. Retries are optional per connection and off by default.
Platform-specific behavior
Here is how Real-Time Sync behaves across each messaging platform we support. Native API latency and event-stream guarantees differ across vendors, which shapes the realistic end-to-end delivery envelope.
| Platform | Behavior | Known limitation |
|---|---|---|
| Slack | Events API push delivery of channel messages, edits, deletes and reactions. | Messages from bots and apps are not relayed. Custom Slack emoji reactions are dropped. |
| Microsoft Teams | Channel messages via Bot Framework; chats without the bot via Microsoft Graph change notifications. | Channel inbound requires the app installed to the team. Graph-notified chats can lag by several seconds. |
| Google Chat | Chat app event delivery for space messages; Workspace Events subscriptions for edits, deletes and reactions. | Inbound edits, deletes and reactions depend on Workspace Events subscriptions being enabled. |
| Zoom Team Chat | Webhook push for messages, replies, edits and deletes. | Reactions sync in channels only; messages are posted from the app. |
| Cisco Webex | Webhook push for message create, update and delete events. | Emoji reactions are not synced on Webex. |
Frequently asked questions
- How fast is SyncRivo message delivery?
- SyncRivo is real time: messages typically arrive within seconds. Delivery time depends on source and destination platform event delivery and API response times, and some paths (such as Teams chats without the SyncRivo bot) can take longer.
- Does SyncRivo use polling or webhooks?
- SyncRivo uses native webhooks and event subscriptions from each platform — not polling. Slack events are delivered via Slack's Events API, Teams events via the Microsoft Bot Framework webhook, and Google Chat via its Chat app events. This avoids polling for channel messages.
- What happens if a destination platform is temporarily down?
- Admins can enable an optional retry queue per connection (it is off by default). When enabled, messages a destination platform could not accept are held temporarily and tried again. Sync activity is visible in the activity log.
- Is there a difference in real-time performance between Slack, Teams, Google Chat, Zoom, and Webex?
- Yes. Each platform's event delivery and API have their own timing characteristics. Teams channel messages arrive through Bot Framework, while Teams chats without the SyncRivo bot rely on Microsoft Graph change notifications, which can add several seconds. When a channel is bridged to several platforms, SyncRivo posts the message to each connected destination.
