Catch activation drops and put follow-up in Slack

Start an Amplitude activation check by webhook and give the team a Slack reminder when the agreed condition appears.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Create a reminder

Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').

Why this helps

A drop in activation can go unnoticed when nobody owns a timely check and follow-up.

  • Makes a defined activation concern easier to spot.
  • Creates a Slack reminder only when the instructed condition is met.
  • Keeps the response attached to a concrete follow-up.

Setup

Build it in a few focused steps.

  • 1Connect Amplitude and Slack once in Notis.
  • 2Create an automation in Automations, New Automation, and name it.
  • 3In one instruction, describe the activation analysis, the condition that warrants follow-up, and the Slack reminder to create.
  • 4Pick a webhook trigger and choose where run reports should go.
  • 5Test with one real example, including a case that does and does not meet the condition.

Questions about this workflow

What starts the activation check?

An HTTP request to the Notis webhook starts it. Amplitude has no listed trigger events here.

Can it identify a drop without a comparison point?

No. Supply the baseline, comparison period, or threshold in the instruction if Amplitude does not provide it in the data returned.
