Carry a Slack DM into a WhatsApp reply

When a Slack DM needs a WhatsApp response, let Notis prepare a contextual reply so you do not lose track of what prompted it.

Trigger

Direct Message Received

Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.

Action

Send reply

Send a reply to a specific message in a whatsapp conversation. this creates a contextual reply that shows which message you're responding to. note: the reply will be delivered to the recipient only if they have texted first.

Why this helps

Moving a conversation between Slack and WhatsApp can make it hard to remember which message needs your attention.

  • Keep the source message in view when drafting the WhatsApp response.
  • Reduce the chance that a cross-app follow-up gets forgotten.
  • Use a reply action designed to reference a specific WhatsApp message.

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 prepare a concise WhatsApp reply based on a Slack DM and preserve the relevant context.
  • 4Pick Direct Message Received as the trigger and choose where run reports go.
  • 5Test with one real DM and conversation; the WhatsApp recipient must have texted your number first.
