Authenticate CustomJS after a new WhatsApp message

Keep message-driven automations connected by checking the CustomJS API key as soon as a WhatsApp message arrives.

Trigger

New WhatsApp Message Received

Polling trigger that monitors for new messages received in TimelinesAI WhatsApp chats.

Action

Authenticate CustomJS API Key

Tool to authenticate a CustomJS API key. Use when verifying a user's API key before making further requests.

Why this helps

A stale API key can silently stop urgent message workflows and create manual recovery work.

  • Catches invalid credentials early
  • Reduces silent automation failures
  • Creates a reliable handoff for later actions

Setup

Build it in a few focused steps.

  • 1Connect TimelinesAI and CustomJS in Notis once.
  • 2Create a new automation and describe that each new WhatsApp message should trigger a CustomJS API key verification.
  • 3Pick the TimelinesAI New WhatsApp Message Received trigger.
  • 4Choose where Notis should send run reports.
  • 5Test with one real WhatsApp message.

Questions about this workflow

Does this send a reply to WhatsApp?

No. It only verifies the CustomJS API key after the message event.

What happens if the key is invalid?

The run report can surface the authentication failure so you can reconnect or replace the key.
