Connect Better Uptime and Slack

When a site or API goes down, the people who fix it and the people who answer customers both need to hear. FlowMattic takes Better Uptime incident, on-call and monitor events and turns them into Slack posts, incident channels, on-call topics and handover messages, running from your WordPress site.

When Better Uptime fires Incident Notification, FlowMattic runs Send Channel Message in Slack with the data from that event.

Better Uptime and Slack workflows you can build

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.

Post Better Uptime incidents to the incidents channel

Each incident appears with the monitor name, cause and status, so engineering and support see the same outage notice at the same time.

Incident NotificationSend Channel Message

Send new and resolved incidents to different channels

A Router reads the incident status. New incidents go to the on-call channel, resolutions go to the customer support channel so agents can tell customers the service is back.

Open a dedicated Slack channel for each outage

A Filter passes only newly started incidents. FlowMattic creates a channel named after the monitor and sets the topic to the incident cause, keeping outage chatter out of general channels.

Show who is on call in the ops channel topic

When the rota moves, the topic of the ops channel changes to the new on-call name, so anyone with an urgent question knows who to ping.

On-call Contact ChangeSet Channel Topic

Message the engineer whose on-call shift starts

The incoming engineer is found in Slack by email and gets a direct message that their shift has started, a quiet check that the handover happened.

Flag paused or deleted monitors to the team lead

Monitor changes go to a private channel. A paused monitor that nobody unpaused is a blind spot, and the lead can spot it in the log.

Share a weekly CSV of every monitor

Each Monday a Schedule fetches all monitors, CSV Creator writes them to a file and Slack uploads it, so the team can review what is watched and what is missing.

Set up: incidents to a channel

At the end, every Better Uptime incident posts its monitor, cause and status to your Slack incidents channel.

Triggers and actions in this pair

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.

Good to know

Incident Notification fires when an incident is created, acknowledged and resolved. Without a Filter or Router on the status, one outage posts three messages.
These workflows only post to Slack, so incidents are not acknowledged from a Slack message. Engineers still acknowledge in Better Uptime or its app.
Slack channel names must be unique. Add the date or incident ID to the name when the same monitor can fail more than once.

Why run this pair with FlowMattic

Better Uptime and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.

Support hears about outages too

Customer-facing teams get the same incident and resolution posts as engineers, so they can answer customers without asking in the engineering channel.

The rota is visible in Slack

On-call changes update a channel topic and message the incoming engineer, which removes the question of who is on duty today.

Alerts handled on your own server

FlowMattic runs on your WordPress site with unlimited runs, so a noisy week of incidents does not change what you pay.

Common questions

How do I send Better Uptime alerts to Slack with FlowMattic?

Add a Slack connection, create a workflow with the Better Uptime Incident Notification trigger and add Send Channel Message. Map the monitor, cause and status into the text, test with one incident and switch it on.

Can I post only new incidents and skip acknowledgements?

Yes. Add a Filter after the trigger that passes only the started or created status. Acknowledged and resolved events stop there, or go down another Router path.

Can each outage get its own Slack channel?

Yes. Use Create Channel after a Filter for new incidents, with a name built from the monitor and the date, then Set Channel Topic with the cause. Invite the on-call engineer with Invite User To Channel.

Can Slack create a Better Uptime incident?

Not from a Slack message with these workflows, which only post to Slack. Create Incident can run from a Webhook or another app's trigger, for example a customer report form.

Will this work if my WordPress site is the thing that is down?

No. FlowMattic runs on your WordPress site, so if that site is offline the workflow cannot run. Monitor other services this way and keep Better Uptime's own alerts for the site that hosts FlowMattic.
