Move a channel decision into a WhatsApp choice list
When a message needs a decision, put the available options in a WhatsApp list that is quick to scan and answer.
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 list
Send an interactive list message to a whatsapp number. list messages allow users to select from up to 10 options in a structured format. great for menus, catalogs, or choices. note: the message will be delivered to the recipient only if they have texted first.
Why this helps
Open-ended Slack threads can make small choices take too long and leave the decision unresolved.
- Present up to ten options in a structured list.
- Help the recipient answer a decision without revisiting a long thread.
- Summarize the Slack context in the prompt for a more useful list.
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 when a Slack channel message should become a WhatsApp list and provide any options that are not present in the message.
- 4Pick Channel Message Received as the trigger and choose where run reports go.
- 5Test with one real decision message; the WhatsApp recipient must have texted your number first.
