Sentry.io catches exceptions and crashes in your apps. FlowMattic posts the Sentry.io events your team should see to Slack: new issues for the engineering channel, production errors for on-call, assignments to the assignee and resolutions for support. For product teams that triage bugs in Slack.

1. TriggerIssue2. ActionSend Channel MessageWhen Sentry.io fires Issue, FlowMattic runs Send Channel Message in Slack with the data from that event.
You build this in the FlowMattic workflow builder on your own site. See the setup steps
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateA Filter passes only newly created issues, so the engineering channel sees each fresh bug once with its title, project and link, and resolved or ignored updates stay out.

View the template A Router reads the environment on each error. Production goes to on-call, staging goes to the developers' channel, so on-call only wakes up for customers' problems.

When an issue is assigned, Find User by Email finds the assignee in Slack and a direct message gives them the issue and link, so ownership is clear.

Resolved issues post to the support channel, so agents can tell the customers who reported the bug that a fix is out.

For issues in a critical project, Create Channel names a channel after the issue and Set Channel Topic adds the Sentry.io link, so the investigation has its own room.

Comments on issues often hold the root cause. Posting new comments to the team channel shares findings with people who do not watch Sentry.io.

At the end, every new Sentry.io issue posts its title, project and link to your engineering channel, and other issue updates are skipped.
Under Connects in FlowMattic, add a Slack connection for your engineering workspace.
Create a workflow with Sentry.io and the Issue trigger, then follow its instructions to send Sentry.io issue events to the workflow.
Raise a test exception in a project so FlowMattic captures the issue fields and the action value.
Add a Filter that continues only when the action is created.
Add Send Channel Message, choose the channel, include the title, project, level and link, test it and switch the workflow on.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Sentry.io and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
New issues reach the team, assignments reach the assignee and resolutions reach support, so every update has a reader.
Filters and Routers on action and environment decide what posts, so the channel holds the bugs people should act on.
FlowMattic runs on your own WordPress site with unlimited runs, so a bad deploy that fires many events adds no per-task fee.
Create a workflow with the Sentry.io Issue trigger, add a Filter for the created action, then Slack Send Channel Message with the issue title, project and link. Test with one exception and switch it on.
Yes. Add a Filter after the Error trigger that continues only when the environment is production, or a Router that sends each environment to its own channel.
Yes. Add a step for your task app after the Slack message, for example a ClickUp task, so the bug is tracked as well as announced.
Yes. Use Find User by Email with the on-call engineer's email, or a Lookup Table that maps the project to a person, then Send Direct Message.
FlowMattic runs on your WordPress site, so if that site is down the workflow cannot run. Keep a direct Sentry.io alert for the site that hosts FlowMattic.
