Auto-fetch Slack conversation threads from WhatsApp replies

When a customer responds in a WhatsApp thread, Notis automatically fetches the full Slack conversation so your team sees the complete history.

Trigger

Interactive Reply Received

Triggered when a customer taps a quick-reply button or selects an option from an interactive list message you sent.

Action

Retrieve conversation replies

Retrieves replies to a specific parent message in a slack conversation, using the channel id and the parent message's timestamp (`ts`).

Why this helps

Conversations span multiple messages and platforms. Context gets lost when you see only the latest WhatsApp reply without the Slack thread history.

  • Maintain full conversation context across WhatsApp and Slack
  • Reduce confusion from fragmented multi-message exchanges
  • Enable faster, more informed responses with complete history

Setup

Build it in a few focused steps.

  • 1Connect WhatsApp and Slack to Notis.
  • 2Create an automation: 'When a customer sends a threaded reply in WhatsApp, fetch the related Slack conversation thread and post it'.
  • 3Select 'WhatsApp: Interactive Reply Received' as your trigger and specify that it applies to threaded/reply messages.
  • 4Notis will match the WhatsApp thread to the Slack channel and fetch all replies.
  • 5Test by posting a message to Slack, then having a customer reply in the threaded WhatsApp message; the Slack thread should appear with context.

Questions about this workflow

Does this fetch entire conversations or just recent replies?

Notis fetches the thread replies starting from the original message. You can customize how many messages to include (e.g., last 5 replies or full thread).

What if the customer doesn't match a Slack thread?

Notis looks for a related Slack message by timestamp or customer ID. If no match exists, it posts a notification so your team knows context may be missing.

Can I post the thread to a specific Slack channel?

Yes. Tell Notis: 'Fetch the thread and post a summary to #customer-support with a link to the full conversation'.

Message Status Updated

Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
