Turn a Slack request into a Cal connection check

When you ask in a channel to connect a calendar, have Notis start or check the Cal connection and report whether authorization is needed.

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

Connect to calendar

Initiates or checks the external connection status for a specified calendar, possibly returning a redirect url for user authorization to complete integration, without altering calendar data.

Why this helps

Calendar setup tasks can stay unresolved because the connection step is easy to postpone after it is discussed.

  • Turns a stated setup request into a concrete next step.
  • Surfaces whether a user authorization step is required.
  • Reduces repeated reminders to finish calendar setup.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Cal to Notis once through the portal.
  • 2Create an automation in the portal, or ask Notis to initiate or check a Cal calendar connection only when a Slack message clearly requests it.
  • 3Select Channel Message Received as the trigger and choose a channel for run reports.
  • 4Test with one real connection request and review any authorization instructions.

Questions about this workflow

Does the connection action grant access automatically?

It may return a redirect URL for the user to complete authorization; it does not silently grant access.

Can it connect any calendar mentioned?

The request should identify a supported calendar and the relevant account.
