Send Slack message
Description
Sends a message to a Slack channel using the organization's connected Slack workspace. Requires an active Slack integration. Branches on success/error so the pipeline can react to delivery failures.
When to use
Use Send Slack message to push notifications, alerts, or reports into Slack directly from a pipeline — for example, to announce that a nightly job finished, to flag a failed HTTP request, or to summarise incoming webhook data. The message is sent through your organization’s connected Slack workspace, so no bot token has to be managed inside the pipeline.
Connect the workspace first: an owner links Slack from the organization’s integration
settings. Without an active integration the node fails on its error branch. Wire the
success and error execution outputs to handle each outcome — for instance, Log
message on success and Fail (or a retry path) on error.
Pins
Input pins
| Pin | Type | Default | Notes |
|---|---|---|---|
| Channel | string | — | The Slack channel to post to, identified by its channel ID. The channel must be visible to the workspace's Flovello integration. |
| Content | string | — | The message text to post. Wire from Concatenate strings or Model to string to build dynamic content. |
Execution pins
| Pin | Direction |
|---|---|
| In | Input |
| Success | Output |
| Error | Output |
Example
Post a summary to Slack after an HTTP webhook is processed. Wire the execution output of the processing step into the execution input of Send Slack message, set Channel to the target channel ID, and wire a Concatenate strings result into the Content input. On the Success execution output, continue the pipeline; on the Error execution output, wire a Log message node so failed posts surface in the execution log.
