How It Works
This trigger listens for messages in Slack channels where the @Markifact bot has been mentioned. When someone types a message that includes @Markifact, the workflow is triggered with the message content and details.⚠️ Important Requirements
Bot Must Be Mentioned:- Only messages that mention @Markifact will trigger workflows
- Regular messages without the bot mention are ignored
- This prevents workflows from triggering on every channel message
- The Markifact bot must be a member of channels you want to monitor

Why isn't my private channel showing in the dropdown?
Why isn't my private channel showing in the dropdown?

Will I know if Markifact received my message?
Will I know if Markifact received my message?
Yes! Markifact automatically reacts with a ⚡ emoji to confirm it received your @Markifact mention. This happens immediately while your workflow is being processed. Look for the lightning bolt reaction on your message to know the bot is working on your request.
I'm testing my workflow but only see test data - why?
I'm testing my workflow but only see test data - why?
Manual testing from the workflow editor shows placeholder data. You’ll see test messages like:“This is a test message” and test IDs like “test_channel_id” and “test_user” instead of real Slack data.To see actual data, you must activate your workflow (turn on the switch at the top) and then go to Slack to send a real @Markifact mention.
I sent a @Markifact message but nothing happened - what's wrong?
I sent a @Markifact message but nothing happened - what's wrong?
Check if your workflow is active! The most common issue is that the workflow isn’t turned on. Look for the switch button at the top of your workflow editor and make sure it’s activated. If the workflow is off, it won’t respond to Slack messages even if everything else is set up correctly.
Do I have to mention @Markifact in every message?
Do I have to mention @Markifact in every message?
Yes, only messages that mention @Markifact trigger workflows. This prevents the bot from responding to every message in a channel. Regular conversation continues normally - only @Markifact mentions activate automation.
Can I use this trigger across multiple channels at once?
Can I use this trigger across multiple channels at once?
