Answer Urgent Slack Mentions From WhatsApp
Channel mentions get buried. Route them to WhatsApp with 3 buttons for quick confirmation or clarification—your team sees you responded, and you stay in flow.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Send interactive buttons
Send an interactive button message to a whatsapp number. button messages allow users to quickly respond by tapping up to 3 predefined buttons. perfect for yes/no questions, quick choices, or call-to-action scenarios. note: the message will be delivered to the recipient only if they have texted first.
Why this helps
You're mentioned in Slack but don't see it until hours later. By then the conversation has moved on, and you've either over-committed or missed the context entirely.
- See mentions instantly on WhatsApp
- Respond without opening Slack
- Your team gets confirmation right away
- Keeps you in your current task longer
Setup
Build it in a few focused steps.
- 1Connect Slack and WhatsApp to Notis.
- 2Create automation: 'When I'm mentioned in Slack, send quick-response buttons on WhatsApp.'
- 3Notis triggers on any Slack channel mention of you.
- 4Tap 'Got it,' 'In progress,' or 'Needs more context' on WhatsApp.
- 5Your response appears as a reaction or comment in Slack automatically.
Questions about this workflow
What if I don't respond to the buttons?
Notis will remind you after 30 minutes (you can adjust). Non-response doesn't stop your work—it's just a reminder.
Can I customize the button options?
Yes. Tell Notis: 'Change the buttons to X, Y, Z' and it updates automatically.
Does this work for @channel mentions?
Yes, but you can filter it: 'Only send for direct mentions, not @channel or @here.'
