Catch urgent Slack updates in WhatsApp
Bring important channel updates to the messaging app you already check, with a short summary and a clear next step.
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 message
Send a text message to a whatsapp number. note: the message will reflect on the recipient's phone number only if they have texted first.
Why this helps
Important Slack updates can disappear in busy channels, leaving you to search for decisions and follow-ups later.
- Surface time-sensitive channel posts without switching apps.
- Ask Notis to summarize the message and state any requested action.
- Keep WhatsApp delivery within its recipient messaging requirements.
Setup
Build it in a few focused steps.
- 1Connect Slackbot and WhatsApp once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Describe that Notis should send a concise WhatsApp alert for urgent Slack channel updates, including the source channel and requested action.
- 4Pick Channel Message Received as the trigger and choose where run reports go.
- 5Test with one real channel message; the WhatsApp recipient must have texted your number first.
Questions about this workflow
Will every Slack channel message be sent?
Describe the outcome you want in the automation instruction. Notis can analyze the received message, but the listed trigger fires for channel messages and does not provide a built-in filter picker.
Can I message someone who has never contacted my WhatsApp number?
The Send message action is delivered only if the recipient has texted your WhatsApp number first.
