FullStory sees what users do in your app: dead clicks piling up, a mobile crash, a custom event such as a failed checkout. FlowMattic posts those signals to Slack so product managers, designers and engineers find out while the session is still fresh. Notes written in FullStory reach the team too, so findings are shared instead of sitting in one account.

When FullStory fires Segment Alerts, FlowMattic runs Send Channel Message in Slack with the data from that event.

FullStory 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.
Ready-made template
Post FullStory segment alerts to the product channel
When dead clicks on a segment pass your threshold, the product channel hears about it with the segment name, so someone can watch the sessions and find the broken element.
Send mobile app crashes to the engineering on-call channel
Each crash FullStory detects goes to the on-call channel with the device and app version, so the engineer on duty can open the session that led to it.
Mobile App Crash→Send Channel Message
Share FullStory notes with the design team
Researchers write notes on sessions in FullStory. Posting each new note to the design channel turns a private observation into something the team can discuss.
Note Created→Send Channel Message
Route custom events to the team that owns them
A Router reads the event name, such as checkout failed or signup error, and posts it to payments, growth or support, so each alert reaches the owners of that flow.
Custom Event→Router→Send Channel Message
Show crash status in the on-call channel topic
Set Channel Topic writes the time and app version of the latest crash into the header, so the on-call engineer sees at a glance when the last one happened.
Mobile App Crash→Date/Time Formatter→Set Channel Topic
Post only some alerts during a crash loop
A Counter tracks crashes as they arrive and a Filter posts only every tenth one, so a crash loop on one build does not bury the channel in identical messages.

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
Segment Alerts fire on the thresholds you set in FullStory, so tune them there. A threshold that is too low will fill the channel faster than anyone can watch sessions.
Custom Event depends on the events your developers send to FullStory. Agree on clear event names first, so a Router can tell them apart.
The fields in the mapping are examples; check the captured alert for what your FullStory account actually sends.

Why run this pair with FlowMattic
FullStory and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
User pain reaches the people who fix it
Dead clicks, crashes and failed flows show up in Slack for product and engineering, not only in a dashboard someone has to remember to open.
Findings are shared, not hoarded
Notes written on sessions reach the design channel, so research turns into conversation and decisions.
Alert volume does not change the bill
FlowMattic runs on your own WordPress site with unlimited runs, so a noisy release week costs the same as a quiet one.
Common questions
How do I send FullStory alerts to Slack?
Connect Slack in FlowMattic, create a workflow with the FullStory Segment Alerts trigger and add Send Channel Message. Include the segment and session link in the message, capture a sample alert and switch the workflow on.
Can mobile crashes go to a different channel?
Yes. Build a separate workflow with the Mobile App Crash trigger and point it at your on-call or mobile channel. Each FullStory event can have its own workflow and channel.
How do I stop a crash loop from flooding Slack?
Add a Counter and a Filter so only some alerts are posted, or a Filter on the app version so known issues are left out. You can also raise the alert threshold in FullStory.
Can custom events trigger Slack messages?
Yes. The Custom Event trigger starts a workflow for events your app sends to FullStory. Use a Router on the event name to decide which channel each one goes to.
