LaunchDarkly posts flag changes to Slack through its native app. SyncRivo bridges the human discussion between Slack, Teams, Webex, Google Chat, and Zoom.

LaunchDarkly has a native Slack integration — but no native Microsoft Teams integration. Flag changes surface only in Slack, and SyncRivo does not relay those app notifications. What SyncRivo can do is bridge the Slack channel where engineers discuss a kill switch with the Teams channel where leadership works.

Flag Events Teams Discuss Across Platforms

LaunchDarkly delivers these events through its Slack app and webhooks. SyncRivo does not relay bot or app messages; it bridges the human discussion.

Flag Toggled On

Feature flag activation events — especially in production — that release engineers and product leadership both want to know about.

Flag Toggled Off / Kill Switch

Kill switch activations and flag-off events that signal a live feature was disabled in response to an incident or degradation.

Targeting Rule Changed

Targeting rule updates — new user segments, percentage rollout changes, individual user targeting — that feature teams and product managers track.

Experiment Started

A/B test and multivariate experiment launch events that engineering and product stakeholders follow.

Variation Updated

Flag variation value changes — especially for configuration flags controlling behavior in production — that engineering and on-call teams need to be aware of.

Flag Archived

Flag archival events — removing old flags no longer serving traffic — relevant to technical debt tracking.

How the Pieces Fit

01

Audit log webhook — all flag changes across all flags

LaunchDarkly audit log webhooks (Account Settings → Integrations → Webhooks) fire for every flag and environment change in the project: flag toggles, targeting rule edits, segment updates, variation changes, and project configuration. Point them at a receiver you operate. SyncRivo does not accept inbound webhooks.

02

Flag triggers — selected high-visibility flags only (Enterprise)

LaunchDarkly flag triggers (Flag Settings → Triggers → Webhook) allow individual flags to fire webhook requests on toggle. Use them for high-visibility flags such as kill switches, billing flags, and experiment variants, pointed at a receiver you operate — not at SyncRivo.

03

Bridge the discussion channels with SyncRivo

Bridge the on-call or releases Slack channel with the Engineering Leads or Product Leadership Teams channel. People on both platforms can then discuss flag changes in one conversation. SyncRivo bridges human messages only; LaunchDarkly app posts are not relayed.

04

Keep the native Slack app for interactive features

LaunchDarkly's native Slack app supports interactive actions — toggling flags directly from Slack, subscribing to specific flag change notifications from Slack. Keep using it for notifications and interactions; use SyncRivo for the cross-platform human conversation.

Flag Event Audience Matrix

Who needs to discuss each flag change — engineering on-call in Slack, product and leadership in Teams. SyncRivo bridges the human discussion between these channels; it does not deliver the flag events.

Frequently Asked Questions

Does LaunchDarkly have a Microsoft Teams integration?▾

LaunchDarkly does not have a native Microsoft Teams integration for flag change notifications. LaunchDarkly has a native Slack integration — the LaunchDarkly Slack app posts flag toggle events, targeting rule changes, and audit log entries to Slack channels, and supports Slack triggers for flag actions directly from Slack. SyncRivo does not receive LaunchDarkly webhooks or relay flag notifications — messages posted by bots and apps are not bridged. What SyncRivo does is bridge the human discussion between chat platforms, so developers on Slack and product or release managers on Teams can talk about flag changes in one bridged channel.

How do I send LaunchDarkly flag change notifications to Microsoft Teams?▾

LaunchDarkly supports outbound webhooks (Account Settings → Integrations → Webhooks) that fire HTTP POST requests when flag changes occur — toggles, targeting rule edits, new flag creation, flag archival. Point a LaunchDarkly webhook at a receiver you operate that can post to Teams. SyncRivo does not receive LaunchDarkly webhooks or relay flag notifications — messages posted by bots and apps are not bridged. SyncRivo bridges the human conversation between Teams, Slack, Webex, Google Chat, and Zoom Team Chat.

What LaunchDarkly events can SyncRivo route to messaging platforms?▾

None. SyncRivo does not receive LaunchDarkly webhooks or relay flag notifications — messages posted by bots and apps are not bridged. LaunchDarkly's Slack app and webhooks cover flag toggles, targeting rule changes, kill switch activations, experiment start and stop, new flags, archived flags, variation updates, and segment changes. SyncRivo bridges the human discussion that follows, for example between the on-call Slack channel and the engineering leadership Teams channel.

How does LaunchDarkly flag trigger integration work with SyncRivo?▾

It does not. LaunchDarkly flag triggers (available on Enterprise plans) let individual flags fire webhook requests when flag state changes, but SyncRivo is not a webhook receiver and has no routing configuration for flag events. Use LaunchDarkly's native Slack app or your own webhook receiver for notifications; use SyncRivo to bridge the human discussion between chat platforms.

Can SyncRivo route LaunchDarkly kill switch events to Teams during an incident?▾

No. Kill switch activation is one of the most time-sensitive flag events, but SyncRivo does not relay LaunchDarkly notifications or other bot and app messages. LaunchDarkly's native Slack app posts the event in Slack. SyncRivo helps with the conversation: bridge the on-call Slack channel with the engineering leadership Teams channel so responders and leadership can discuss the incident together.

Does LaunchDarkly have a webhook integration for audit log events?▾

Yes. LaunchDarkly supports audit log webhooks (Account Settings → Integrations → Webhooks) that send HTTP POST requests for all flag and environment changes — including flag toggles, targeting rule updates, segment edits, and project configuration changes. This webhook fires for all flag activity across all flags in the project, not just specific flags. For flag-specific notifications on selected flags only, use LaunchDarkly flag triggers instead. SyncRivo does not accept either webhook type.

Bring Every Team into the Flag Change Conversation

LaunchDarkly posts flag changes to Slack. SyncRivo bridges the human discussion to Teams, Webex, Google Chat, and Zoom, so everyone can talk about a change on their own platform.
